JUMP TO: Brand Recommendations - Updated 2014

Once a standard supplement in traditional European societies, cod liver oil provides fat-soluble vitamins A and D, which Dr. Price found present in the diet of primitives in amounts ten times higher than in modernized diets. Cod liver oil supplements are a must for women and their male partners, to be taken for several months before conception, and for women during pregnancy. Growing children will also benefit greatly from a small daily dose.

Cod liver oil is also rich in eicosapentaenoic acid (EPA) and docasahexaenoic acid (DHA). The body makes these fatty acids from omega-3 linolenic acid. EPA is as an important link in the chain of fatty acids that ultimately results in prostaglandins, localized tissue hormones while DHA is very important for the proper function of the brain and nervous system. Those individuals who have consumed large amounts of polyunsaturated oils, especially partially hydrogenated oils, who are suffering from certain nutrient deficiencies, or who have impaired pancreatic function, such as diabetics, may not be able to produce EPA and DHA and will, therefore, lack important prostaglandins and necessary fats for the brain unless they consume oily fish or take a cod liver oil supplement.

Buy cod liver oil in dark bottles and store in a cool, dark, dry place. Please read Vitamin A, Vitamin D, and Cod Liver Oil: Some Clarifications below for amounts to give to adults and children and for recommended brands. Cod liver oil is easy to take when stirred into a small amount of water or fresh juice.

Dr. Price always gave cod liver oil along with high-vitamin butter oil, extracted by centrifuge from good quality spring or fall butter. He found that cod liver oil on its own was relatively ineffective but combined with high vitamin butter oil produced excellent results. The butter oil contains what he called Activator X, now considered to be vitamin K2, which works synergistically with vitamins A and D (see Chris Masterjohn's article "On the Trail of the Elusive X Factor: A Sixty-Year Old Mystery Finally Solved"). Your diet should include sources of vitamin K, such as good quality butter from grass-fed cows and/or high-vitamin butter oil, fat from grass-fed animals, cheeses from grass-fed animals and duck or goose liver, along with cod liver oil.

Vitamin A, Vitamin D & Cod Liver Oil: Some Clarifications

Several visitors to our website have noted inconsistencies in various statements about vitamin A, vitamin D and cod liver oil. These issues revolve around questions of dosage and safety.

Vitamin A Dosage

We have pointed out that concerns about vitamin A toxicity are exaggerated. While some forms of synthetic vitamin A found in supplements can be toxic at only moderately high doses, fat-soluble vitamin A naturally found in foods like cod liver oil, liver, and butterfat is safe at up to ten times the doses of water-soluble, solidified and emulsified vitamin A found in some supplements that produce toxicity.(1) Additionally, the vitamin D found in cod liver oil and butterfat from pasture-raised animals protects against vitamin A toxicity, and allows one to consume a much higher amount of vitamin A before it becomes toxic.(1-3) Liver from land mammals is high in vitamin A but low in vitamin D, and should therefore be consumed with other vitamin D-rich foods such as lard or bacon from pasture-raised pigs, egg yolks, and oily fish, or during months in which UV-B light is sufficient to provide one with adequate vitamin D.

As a general guideline, we recommend the following doses of vitamin A from cod liver oil, along with a nutrient-dense diet that contains other vitamin A-rich foods:

  • Children age 3 months to 12 years: A dose of cod liver oil that provides about 5000 IU vitamin A daily, obtained from about 1 teaspoon of regular cod liver oil or ½ teaspoon of high-vitamin cod liver oil.
  • Children over 12 years and adults: A maintenance dose of cod liver oil that provides about 10,000 IU vitamin A daily, obtained from 2 teaspoons of regular cod liver oil or 1 teaspoon of high-vitamin cod liver oil.
  • Pregnant and nursing women: A dose of cod liver oil that provides about 20,000 IU vitamin A daily, obtained from 4 teaspoons regular cod liver oil or 2 teaspoons high-vitamin cod liver oil.

Please note that these recommended doses are 2-5 times greater than the U.S. RDA for children, 4 times greater than the U.S. RDA for adults and 8 times greater than the U.S. RDA for pregnant women. The RDA values are based on studies conducted in the general population, which is now recognized to be largely deficient in vitamin D. For a discussion of studies showing that vitamin A consumption up to 30,000 IU per day by pregnant women does not result in a greater risk of birth defects, see Vitamin A for fetal development. This article also describes the vital role played by vitamin A in the development of the fetus. Pregnant women may wish to consult their health practitioner about taking cod liver oil during pregnancy.

Individuals under stress or wishing to use cod liver oil to treat a disease condition may take much larger doses, even up to doses providing 90,000 IU vitamin A per day, for a period of several weeks.

Vitamin D Dosage

Our recommended brands of cod liver oil (see below) will provide with the above recommended dosages for cod liver oil about 500-1000 IU vitamin D for children, 1000-2000 IU vitamin D for adults, 2000-4000 IU vitamin D for pregnant and nursing women and up to 9000-18,000 IU for those taking large amounts of cod liver oil to deal with stress and disease.

In 1997, the Food and Nutrition Board of the US Institute of Medicine set the tolerable upper intake level (TUIL) for vitamin D at 2000 IU per day. However, the vitamin D content experts on the Upper Limits Panel objected to this limit, and several prominent vitamin D researchers have called for an upward revision of the limit. Experiments show that even during the winter with a low vitamin D intake, humans will exhaust stores of vitamin D at a rate of 3000-4000 IU per day, an amount that many people require to maintain optimal levels of the vitamin in the blood. Extensive exposure to summer sun at mid latitudes naturally produces levels of vitamin D in the blood equivalent to what is attained by supplementing with a continued daily dose of 10,000 IU, suggesting humans are designed to tolerate such large amounts of vitamin D.(4)

If you are a lifeguard or spend a lot of time in the sun, you do not need to take supplemental vitamin D; however you still need to consume adequate vitamin A. Animal studies show that even moderate amounts of vitamin D increase the body's need for vitamin A, whether the vitamin D is provided in the diet or by UV light (2,5). So, if you cut back or eliminate cod liver oil in the summer, be sure to consume plenty of oily fish, liver, butterfat and egg yolks from grass-fed hens to ensure adequate vitamin A.

For a discussion of Vitamin D Toxicity, see http://www.vitamindcouncil.org/vitaminDToxicity.shtml

This does not mean we do not recommend that some individuals have their vitamin D levels tested. Such testing can be very useful in determining vitamin D status and the effectiveness of cod liver oil or vitamin D supplements. Optimal serum vitamin D levels should be in the range of 30-50 ng/mL (see discussion at [link "Potential Dangers of Vitamin D, page 24 of Spring 2009]).

Brand Recommendations - Updated 2014

Most brands of cod liver oil go through a process that removes all of the natural vitamins. The resultant product contains very low levels of vitamin A and virtually no vitamin D. Some manufacturers add manufactured vitamins A and D to the purified cod liver oil and until recently, one manufacturer added the natural vitamins removed during processing back into the cod liver oil. Fortunately, we now have available in the U.S. a naturally produced, unheated, fermented high-vitamin cod liver oil that is made using a filtering process that retains the natural vitamins.

The high-vitamin fermented cod liver oil is sold as a food so does not contain vitamin levels on the label. However, after numerous tests, the approximate values of A and D have been ascertained at 1900 IU vitamin A per mL and 390 IU vitamin D per mL. Thus 1 teaspoon of high-vitamin fermented cod liver oil contains 9500 IU vitamin A and 1950 IU vitamin D, a ratio of about 5:1.

Based on these values, the dosage for the high-vitamin fermented cod liver oil is provided as follows:

  • Children age 3 months to 12 years: 1/2 teaspoon or 2.5 mL, providing 4650 IU vitamin A and 975 IU vitamin D.
  • Children over 12 years and adults: 1 teaspoon or 10 capsules, providing 9500 IU vitamin A and 1950 IU vitamin D.
  • Pregnant and nursing women: 2 teaspoons or 20 capsules, providing 19,000 IU vitamin A and 3900 IU vitamin D.

Please note that the fermented cod liver oil contains many co-factors that may enhance the body's uptake and usage of vitamins A and D; in fact, many have reported results equivalent to those obtained from high-vitamin cod liver oil with half the recommended dose, that is ¼ teaspoon or 1.25 mL for children age 3 months to 12 years; ½ teaspoon or 5 capsules for children over 12 years and adults; and 1 teaspoon or 10 capsules for pregnant and nursing women.

As of Spring, 2009, we recommend the following brands of cod liver oil. Sources of high-vitamin fermented cod liver oil and high-vitamin cod liver oil with natural vitamins added are in the BEST category; sources of processed cod liver oil with synthetic vitamins in the right proportions are in the GOOD category. We do not recommend brands of cod liver oil that have only low levels of vitamins A and D.

There Is No Good Cod Liver Oil On The Market Anymore
written by Bean Bagger, Apr 16 2014
Hi all,

I have tried practically all the cod liver oil on the market and none really worked like the Premier Research Labs QUANTUM Cod Liver Oil.

It was strangely taken off the market at the height of its popularity with some kind of vague excuses.

Why do you think it worked?

I gave it to my elderly mom and me (of course) and it gave a glow on the skin like no other cod liver oil to this day. Not even the fermented ones and I believe kept her alive and able to fight the ravishes of old age and all its inherent ills it brings.

Unable to obtain it anymore she would die a few years later and succumb to the diabetes and old age. People would complement my mother on her glowing skin and youthful appearance and women would be jealous of my complexion.

Sadly, none of the oils today can duplicate that and I have recently heard that synthetic vitamins are actually poisons to the body with the opposite affect of helping it.

I will reluctantly buy the "Best" brands as I have been using Sonne Cod Liver Oil rated "Good" and really see no change in my skin tone and someone also commented that they use synthetic vitamins which I did not realize.

Do you I think there is a "health" conspiracy? Yes!

Real cod liver in its own oil
written by Gary Fleischmann, Mar 12 2014
I have recently come across small cans of real cod liver in its own oil. The only addition is some salt which doesn't taste excessive.. This cod liver is from Icelandic waters. In all the literature here there seems to be no discussion on consuming the actual liver in its own oil, which it turns out is actually quite tasty. Would this source be considered as good as oil supplements on their own?? I imagine the only real thing to consider is the heat treatment the liver is exposed to for canning.

Garden of Life not distilled or deodorized
written by Jeremy, Mar 11 2014
I recently spoke with one of the sales reps who contacted the educators for garden of life. She told me that the Old World CLO is not Distilled or Deodorized which means that the A and D are not removed and also means that the D is not synthetic. This also would mean that the product will naturally contain a non-standardized amount of both A and D, since they are not added in "after the fact."
Any brands that deodorize or distill their oil is almost certain to add synthetic D that comes from irradiating lanolin. This is the "naturally derived D" they refer to on the bottle.
CLO for diseases
written by Starly, Feb 13 2014
Great site. Thanks for all to info. The article mentions that CLO can be taken in higher doses for certain diseases. I'm wondering what diseases it is useful for?
Reply to Carla and Mac
written by tjboyd, Jan 23 2014
Weston Price was looking at teeth in particular and what worked best to stop cavities or even remineralize teeth. The synergy between vitamin A & D in CLO and X-factor (K2) in butter oil worked best for him. There are other problems that can be helped in cases where you are deficient in vitamin A or D by CLO alone. If you already have some other source of K2 in your diet, you may not need the butter.
It is my understanding that fermented cod liver oil was not available when Price was practicing.
Combo of CLO and butter oil questions unanswered
written by Carla, Jan 22 2014
Some very interesting questions were asked by Mac Low back in April 2012 that I didn't see answers for. (This is a very busy page, so I can see why!) I've copied below. I think I read somewhere that Price most likely used processed CLO (vs. fermented), so his second point is especially relevant.

Any chance of getting answers? To get the best, most unprocessed products is quite costly, and I think answers to his questions could help pinpoint which and in what combinations are essential.

Thanks, WAP. You rock.

"He (Dr.Price) found that cod liver oil on its own was relatively ineffective but combined with high vitamin butter oil produced excellent results."
Fallon/Enig

Raises so many questions.
Was C.L.O.ineffective by itself?
That would suggest that it needed butter (oil) to work, and that the history of its benefits, aside from using with butter, was non-existent.
That's absurd, considering almost all cultures who used C.L.O., did so without butter, and derived benefits, including from rickets and such.

What is meant by 'relatively' ineffective?
Relative to the effects only derived from Vitamin K (X factor) support?
-Like minerals and Vit A+D utilization and such.

What type-quality of C.L.O. was Dr. Price using at the time?
Processed or fermented?
Perhaps, if it was processed, it needed butter lipids to help assimilate.
But if fermented or otherwise minimally processed, so as not disturb key lipid and enzyme factors, then butter (oil) should not be needed with C.L.O.
No??

Look forward to relevant reply's. Hope questions I posed, can be answered.
Thank You WAPF, for so much.

written by Gavin, Nov 12 2013
If this is to be a lifestyle, then I shouldn't have to carry CLO around with me when I travel. Those that live in countries not listed might find it easier to simply fish for any local fishes, and when gutting, select the parts you wish to eat such as the liver. Back to tradition, eh? Now you have something on your todo list when you travel: fish local waters, eat the fish.

Rancidity / oxidation
written by Alex, Aug 13 2013
My understanding is that you do not recommend fish oil due to high heating and therefore potential rancidity of fish oil, however, I am wondering, why would cod liver oil be any different than fish oil in turning rancid? I am questioning the stability of standard CLOs in the "good" category, not the unique fermented version under "best."

Artificial Vitamins and Soy
written by Deb K., Jun 04 2013
From my investigation in emailing two companies that are recommended as carrying a "good" brand of CLO:

Garden of Life Olde World Icelandic CLO contains soy listed in ingredients as the alpha tocopherol. I bought it from Vitacost which says it does not contain soy on the web site but on the bottle it reads "may contain soy". I wrote GOL and asked what kind of soy and they said it was distilled and it was in minute amounts to keep the oil from going rancid.

Swanson double strength CLO tablets contain artificial vitamins. The company that makes "ecoMarine" for Swanson wrote me and explained that the Swanson double strength CLO contains both natural and artificial vitamins. I think they were a bit nervous about revealing that since I got another email from someone completely different stating that I should talk to Swanson about it.

Garden of Life Oceans 3 cod liver oil and other Oceans 3 products are mostly omega 3 supplements which you can easily overdose on so we recommend being careful with that. The cod liver oil also uses vitamin E from soy and has barely any vitamin D. We would not recommend it.
Garden of Life

Garden of Life has a new line called Oceans. The Ocean's Mom says it has 350mg of DHA and 15mg of EPA. No mention of vitamin A and D. This is a prenatal and breastfeeding version. They say that they have a very high standard. I was able to talk to one of the Vice Presidents of the Company and he assured me that their whole line is continuously tested by outside firms for quality and purity. They only use the highest quality of product is what they say their standard is. It is much cheaper than the Fermented oil but about the same price as the Good quality products on the list.

Fermented cod liver oil helped me with my teeth/gum pain.
written by Lisa @ Lifetothefulest.net, Mar 07 2013
I'm a fan of fermented cod liver oil. I originally bought this for my kids. They don't always eat healthy foods. They still eat junk foods and candy. It's so hard to avoid. Many events serve this kind of foods, birthday, halloween, valentine, christmas, and so on. When we go out of town or to the park, the choice of foods are limited as well, mostly pizza , burger or hotdog.
I'm afraid they will get sick if I don't give them healthy food at home. I give them cod liver oil at home. I usually add it on their soup. Thanks God. They're healthy overall, despite of many junk foods they ate. Last time I had sensitivity in my gum and teeth. It happen twice already for the last couple months. I took 1 teaspoon of cod liver oil 3 times a day for 3 days, and the pain is gone. It's an amazing product. By the way, at home I try to eat healthier and more nutritious foods. Once or twice a week, I make green smoothies, made with raw organic seeds, organic berries, and organic greens. My kids love this smoothies too.

We have taken a look at the ingredient details and the amount of vitamin A per recommended dose is fairly low so you would have to take a lot and then run the risk of getting too much omega 3.

I just wanted to tell you how much I appreciate this list. So many websites endorse only one specific (unaffordable)brand. It can be very off-putting for those of us who don't have the means. This is very helpful for someone who is trying, but can't always afford "the best".
Price of CLO
written by Kate, Dec 12 2012
I just don't see how I can possibly afford the best category. Garden of Life is so much cheaper that I wonder about the quality. This is overwhelming and makes me not want to buy any at all. Surely, I'm not the only one who feels this way!

On his website, Chris Masterjohn said (in 200smilies/cool.gif, "My current opinion is that we should be cautious, using small amounts of high-vitamin cod liver oil to provide both fat-soluble vitamins and very modest amounts of omega-3 fatty acids". He also mentions on his site that a normal dose is 1/2 teaspoon for adults. So, why does WAPF recommend twice that amount for adults? I'm confused since he seems to be cautioning us to go easy on FCLO. I'm worried that I'm taking too much FCLO by taking a full teaspoon every day for the rest of my life! Thanks in advance.

To Paulo - Just above the recommendation list it says:
"sources of processed cod liver oil with synthetic vitamins in the right proportions are in the GOOD category. We do not recommend brands of cod liver oil that have only low levels of vitamins A and D."
So I wouldn't be surprised if it does have synthetic vitamins in it.

Swanson double strength Cod Liver Oil capsules
written by Paulo, Nov 09 2012
I am suspicious of the Swanson double strength Cod Liver Oil.
I suspect it contains added synthetic Vitamin A content for a couple reasons.

It is the cheapest per dose of any source found.
It has 6 times more vitamin A than the more expensive Swanson EFAs Pristine Norwegian Cod Liver Oil (SWE04smilies/cool.gif which claims to be minimally processed cold pressed.

I would like to believe but it doesn't make sense. I see it is listed in the Weston list as GOOD.

6 mo old with vitamin deficiency
written by Sailaja, Nov 03 2012
Hi,

I have a 6 mo old baby that has been diagnosed with vitamin d deficiency. She was tested for something else and the vitamin D findings were totally by chance. She is doing ok for her age milestones wise. She is standing on all all fours and stands up if supported. Her vitamin D (25 Hydroxy) was 9.4 ng/mL and 23.50 nmol/L. Is it enough if I give her high vitamin cod liver oil and take her out in the sun to get her vitamin d levels back to normal? And what should the dosage be. Please advise. Thanks a ton! I am currently in India. There is plenty of sunshine here.

Liquid or pill form & cod liver oil versus fish oil
written by Arti, Jun 19 2012
Hi all,
I'm very impressed with the many nutritional benefits of cod liver oil! My mom just recently told me that her dad used to make her & her siblings drink it every day (in India)! It's amazing how much we can learn from "less civilized" countries! She said it tasted horrible so she is in favor of pill form. I was intending to buy the liquid form, but are there
disadvantages or advantages with taking the pill form? Also, is there any issue with taking the flavored liquid formulas? I'm currently nursing my 11-month-old baby & taking prenatal vitamins (New Chapter Organic Perfect Prenatal) & fish oil pills (Nordic Natural Omega D-3). Is it okay to take cod liver oil or should I wait to take the cod liver oil until after I'm finished nursing? Thanks for any tips!

We can't say for each individual what is the optimum amount of each vitamin. We're a little more concerned that the balance between vitamins, especially A & D is good. I don't think you necessarily need consistent daily doses as long as you get some quality sources on a regular basis.
cod liver questions
written by Erica Etelson, Jun 01 2012
@tjboyd: Thanks for your reply: (1) Can you say more about getting too much Omega-3 or point me to an article about this -- I had thought you couldn't get too much of this. (2) Also, if I eat beef/chicken liver once a week, should I be concerned about ALSO taking cod liver oil daily (too much Vitamin A)? Should I skip the cod liver on the days I eat beef/chicken liver? (3) And is it just as effective to get Vit A in a once weekly mega-dose (by eating liver) vs. getting a more moderate dose on a daily basis? (4) Same question for Vitamin B-12: does eating kidney once a week suffice or should I also supplement daily? Lots of questions...thanks for taking the time to respond!

We recommend cod liver oil for the vitamin A & D. Some omega 3 is OK but it is easy to get too much so we don't recommend omega 3 supplements. All fish oil companies test for mercury and other toxins. If they don't meet standards, by regulation their product does not get into the US.

Re: Seven Seas
written by Neil B, May 10 2012
Hi John,

From the response that you've got from Seven Seas, they're confirming that their supplement is mostly a synthetic product, with nothing much natural of any real value. You'd be better off buying one of those fish oils recommended above, as the oil is fermented, a process that retains the vitamins you want without the need to add anything synthetic to it. They are fermented the way nature intended.

Seven Seas cod liver oil
written by Jon Pellington, May 02 2012
Hi guys, I contacted seven seas directly and had quite a good response, I think over all it is a good brand to use.

Below is the response email I got to the question "do you use synthetic vitimin A & D"

=======

Hello Jon

Thank you for your enquiry regarding Seven Seas Supplements.

Cod liver oil is a natural product and will vary in its content of vitamins A and D as well as the omega-3 polyunsaturates EPA and DHA. The oil is extracted from the livers of cod by gentle heating. However, the resultant 'raw' oil is not suitable for human consumption and must, therefore, undergo some processing. We have marketed refined cod liver oil for over 70 years and use refining processes, developed over this period, that are as gentle as possible while sufficiently effective in order to produce a golden, bland-tasting, quality supplement.

Levels of vitamins A and D decline throughout all the processing steps starting from the point of extraction. As these levels are usually laid down in the product specification, A and D must on occasions be added to meet these specifications. We add retinyl palmitate (Vitamin A) and Vitamin D3 cholecalciferol. Although synthesised, the chemical forms of these compounds are those that occur in natural foods. These vitamins are not 'artificial' and are not toxic. They have been used by the food, food supplement and pharmaceutical industries for very many years and are approved for use by all relevant national and international authorities. Many foods in their 'raw' state are not suitable for human consumption and must, therefore, be processed. This may result in nutrient losses and the levels are often restored.

We have a large ongoing New Product Development programme and we follow scientific and regulatory developments closely. If there is scientific consensus that a compound or ingredient is of concern or if there is a regulatory requirement, we will investigate the use of suitable alternatives in order to improve the quality and health-promoting properties of our products.
Thanks Patricia

My kids reaction to the butter oil product may be an oxolate reaction and leaky gut problem. I never heard of oxolates before, but it makes sense to me now, esp. since the kids have been using an electronic parasite zapper (Dr. Hulda Clark). They have been releasing huge amounts of parasites from thier bodies, which would explain the leaky gut connection. I will keep zapping them and try to use the oil in another month, when the parasite problem is under control and the gut (hopefully) has healed.

Carlson's Super 1000mg soft gels are 2,000IU vitamin A to 400IU vitamin D - a ratio of 5:1 My understanding is that this is a good ratio. The vitamins themselves are natural source. They do make a low vitamin A version so perhaps there is confusion. I have found this brand to be inexpensive and reliable - vitamin D blood levels do respond to this formula. Please reconsider your recommendation regarding Carlson's brand cod liver oil.

"He (Dr.Price) found that cod liver oil on its own was relatively ineffective but combined with high vitamin butter oil produced excellent results."
Fallon/Enig

Raises so many questions.
Was C.L.O.ineffective by itself?
That would suggest that it needed butter (oil) to work, and that the history of its benefits, aside from using with butter, was non-existent.
That's absurd, considering almost all cultures who used C.L.O., did so without butter, and derived benefits, including from rickets and such.

What is meant by 'relatively' ineffective?
Relative to the effects only derived from Vitamin K (X factor) support?
-Like minerals and Vit A+D utilization and such.

What type-quality of C.L.O. was Dr. Price using at the time?
Processed or fermented?
Perhaps, if it was processed, it needed butter lipids to help assimilate.
But if fermented or otherwise minimally processed, so as not disturb key lipid and enzyme factors, then butter (oil) should not be needed with C.L.O.
No??

Look forward to relevant reply's. Hope questions I posed, can be answered.
Thank You WAPF, for so much.

Julie, I don't think your kids had a reaction to gluten, but to OXALATE. Chocolate (and wheat and other grains) is very high in oxalate and can cause reactions "to gluten". That's what happened to my girl. The best place to read the science of oxalate chemistry is Susan Owens discussion group on yahoo! http://health.groups.yahoo.com..._Oxalates/

If they have a leaky gut, they are absorbing excess oxalate and affecting their biochemistry. The good news is that the low oxalate diet is gluten free and equal to none in gut repair. It is not a "forever" diet, people graduate! smilies/smiley.gif Good luck in your health journey.

Liver and autoimmune disease and cod liver oil
written by Margie M, Apr 07 2012
I have Cree heritage and have hereditary severe fatty liver and autoimmune problems, probably pbc or overlap. As a very young child my skin was extremely rough and dry. Doctors could not seem to find a solution. As a teenager I began to supplement with vitamin A in the form of fish liver oil and noticed a complete cure of my extremely dry skin within a week of taking it, per the label instructions. With the onset of my acute liver disease as a young adult, I was told to discontinue taking any fat soluable vitamin. I know now that I do not metabolize fats properly and am essentially malnutritioned without proper supplementation. A lot of damage has been done to my body. Cod liver oil is the safest supplementation product for me because it contains a low dose that can be titrated based on the number of capsules I take. I also have vitiligo and it has improved and reduced the vitiligo by conditioning the skin (the more damage, the more vitiligo). Because of my metabolic problems I cannot get any vitamin A benefit from beta carotine, but need supplementation from oils. I noticed that better vitamins contain vitamin A in both forms, perhaps the substitution of beta carotine for fish liver oil in childrens vitamins might be responsible for rises in ADD and ADHD and other health problems as some children may not metabolize these nutrients as well as others.

Hello, I have been researching FCLO and Green Pasture's brand. I cannot find very much of their testing for toxins on their site and I don't know how they keep the Cod fresh from the Arctic to Nebraska. Is Nitrogen used and how is the fish handled from boat onwards? I know Nordic Naturals uses Nitrogen.
Second, I see under GP "PUrity Statement" that the Peroxide Value noted is 10. I read that the Council for Responsible Nutrition’s Voluntary Standards for Omega 3′s list the Peroxide Value as a MAX of 5 mEq/kg. 10 is double this. I am wondering also what the Anisidine values are and the TOTOX values.

Also, I know the fish is fermented, but I thought that some level of molecular distillation is needed in order to remove toxins and contaminants. Is this true? I know it is necessary to meet California’s Prop. 65. I see GP have N/A here and I am assuming you don’t meet it b/c you are not marketed as a supplement.So how are toxins removed?

Would love some help! Thanks!

I think if the previous posters are experiencing thyroid symptoms from taking clo they should get test for anti thyroid/anti tpo antibodies (see Stop the Thyroid Madness website for all recommended tests) and read Dr. Brownstein's Iodine: Why We Need It book. It's possible that extra iodine is stimulating your thyroid to produce more hormone as evidenced by a high TSH. More thyroid hormone is usually a very good thing - unless your body has decided it is allergic to it. Gluten intolerance is first step as the gluten protein is identical to the thyroid protein - and an allergic reaction to one means attacking the other.
Invaluable supplement healed me!

I was so impressed with results of taking fermented cod liver oil with butter daily, that after two years on the supplement, I joined this organization and have followed their research and writings. South Asian vegetarian raised, my skin was very very sensitive and my gums were rapidly receding at 40. Also, I had cramps that seemed to be getting worse monthly. My skin is now no longer deemed "sensitive" by my aesthetician and has cleared up - it requires minimal maintenance now. My gum recession halted and my gums grew "spongy" as well, and I actually enjoyed regular cleanings. Both service providers demanded to know what I had done, but didnt seem to believe it was due to the supplements. My cramps are now fixed far more quickly with a primrose supplement. Thank you so much for your recovery of these ancient foodways and sacred foods for women. My skin is my best advertisement for the supplement.

The article I referred to in my previous post was the update on CLO manufacturing which is dated 2009 and is the same article you refer to in your link. If you read that carefully you never see any reference to fermented CLO from Europe. He refers to natural CLO under the Blue Ice label from Europe but natural is not the same as fermented and not all Blue Ice was fermented (although it is now). I personally visited Green Pasture in NE in summer 2008 and saw the fermented CLO production which had been going on for a while at that point so I know he didn't just start producing it here in 2009. I looked in the vat and saw (and smelled) the fermenting livers. Soooo, I'm going to stand by what I said in my previous post. Nobody has done more meticulous testing of their product than Dave Wetzel. Most of those results are posted on his website and you can check it out for yourself.

written by Monica, Jan 03 2012
No, that is not quite right. You said "FCLO has only been produced (in the last century at least) by GP in Nebraska." however, GP imported European produced FCLO sold as Blue Ice FCLO up until about 2 years ago when they (GP) started manufacturing it in Nebraska. Dave Wenzel talks about the decision to manufacture himself here http://cdn.radiantlifecatalog....ticles.pdf

I have been a long term user of Blue Ice FCLO but stopped for reasons of constant travel about 2 + years ago. When I went to repurchase, it was at the time of re-location of manufacture from Scandinavia to Nebraska.

All the articles on FCLO on WPA (here: http://www.westonaprice.org/cod-liver-oil) predate the transfer of manufacture of FCLO from Europe to Nebraska. Note Item 3 on that list 'Cold Liver Oil Manufacturing by Dave Wenzel' (of GP) is dated 2006. At this time the FCLO was manufactured in Europe.

Please do not misinterpret my query. I have been a long term user of FCLO (2years +) and am very very keen to purchase again as I support the product but seek some assurance that the quality of the product remains comparable to that manufactured in Europe - especially given the 'traditional' nature of the product and what I assume to be nuances associated with its manufacture as it is a traditional food and the environment in Nebraska is very different to that of Europe/Scandanavia - where it was produced until recently.

I just wonder whether the product has been reviewed since the transfer of manufacture to US as most articles pre-date this.

Again, please do not get me wrong as the purpose of my query is to gain some assurance which would enable me to re-purchase the product with my previous confidence. Thats all!

DHA/EPA ratio

I'm sure there are some differences between the fermented CLO by Green Pasture and what was made more than 100 years ago. It's not scientifically possible to compare the 2 since we don't have any from that long ago. Whether it is better now or not, it is our opinion that fermented cod liver oil is the best available now. The article at http://www.westonaprice.org/co...anufacture was written after GP started producing FCLO and FCLO has only been produced (in the last century at least) by GP in Nebraska. They used to sell other CLO from Europe but it was not fermented.
FCLO - Country of Origin and manufacture issue
written by Monica, Jan 01 2011
Blue Ice used to be made in Scandanavia (Denmark/Norway) but in recent years (about the the last two??), Green Pastures has been producing the traditional food, FCLO, in Nebraska.

Given the ‘traditional food’ nature of the fermentation, how can we be certain that the technique used by GP successfully produces the same quality as before? Temperature, technique and many nuances and subtleties in production technique will vary.

Now please dont get me wrong as I have used FCLO for many many years and do value it highly. However I believe my questions are valid given the traditional nature of the food.

I note that the WPA articles on the website predate the change in country of manufacture and were written when the product was made in Europe and imported by GP to USA.

Just how can I have confidence that the quality of the product remains unchanged from that of its European manufacture?

I have tried to contact BP about this but cannot get a straight answer - even one as basic as from what country is the cod liver sourced? My answer was artic!

How old is that bottle? I don't have a bottle in front of me (or a frontal lobotomy) but the Garden of Life website says 200IU per serving. They used to be 400IU or more but changed it several years ago. One thing to keep in mind is that manufacturers are constantly changing their products so this info is accurate at the time it is written. It is possible they recently changed it again and haven't updated their website. Vitamin A to D ratio is our only issue with Garden of Life CLO.
According to labels, Garden of Life (not not recommended here) has more D than Sonne's. What's going on?
written by daphneb10, Dec 19 2011
Hi - I'm really disheartened about all this and feel like there is a hidden agenda. I have a bottle of Garden of Life in my fridge - it claims 450 IU / teaspoon of Vit. D. Looked up Sonne's online and they show their label, which claims 400 IU / teaspoon Vit D. (I don't think anyone knowledgable would think you get all your vit. D from CLO?) Yet just above you say you've stopped recommending Garden of Life because of low vitamin D. Should I throw away my Garden of Life CLO? Do you have purity / quality concerns about Garden of Life? Jordan Rubin used to be tight with the WAPF which is why I started buying Garden of Life and feeding it to my children. Was there a falling out? Personal, or concerns about quality came up? I need to know whether to feed it to my kids or throw it out. Again, really disheartened by this smilies/sad.gif

Seven Seas cod liver oil (just plain liquid, not high strength) appears to have synthetic vitamin A & D which would not be good. The higher strength versions have more omega 3 which could be too much for many people.

First, WAPF has no commercial interest in the fermented cod liver oil. Rather, we are so grateful that Green Pasture has returned to the old way of making it. We will support any company that makes cod liver oil or fish liver oil in the old fashioned way. The cod liver oil that our mothers and grandmothers got was made in the old fashioned way. Today most cod liver oil is so highly processed that most of the vitamins are taken out.

written by Judy, Oct 31 2011
Our Mothers and Grandmothers swore by the good old fashioned cod liver oil. With the "new" fermented brands, is the WAPF now saying there were no health benefits to our ancestors who swore by the use of cod liver oil? I don't know a more delicate way to ask this next question, and no offense is intended, but what relationship/interest does WAPF and it's leadership have to the makers of the fermented brands? You must recognize that consumers are bombarded daily with health claims by professionals whose interest lie solely in pushing their own brands and products, leaving consumers wary of anyone who attach health benefits to a brand, The information given on this website is so vast and complicated at times that I am left frustrated in trying to determine what is really the best for myself and my family.

We don't know of any scientific studies that have established an exact formula and don't have any reason to believe you have to be exact. You can take anywhere from half as much butter oil as FCLO to the same amount of butter oil as FCLO. If you take more, I seriously doubt you will explode - but you might go broke.

I wrote that Carlson soft gel Cod Liver Oil Super 1,000 mg capsules are listed above under Good because they are not fermented. The main reason that they are listed under Good is because they do not qualify as what we consider high-vitamin cod liver oil. You need to take 4 capsules to get the vitamin A & D we recommend and you could be getting too many polyunsaturated oils.

The right proportions are 10 or fewer units vitamin A to one unit vitamin D, and with at least 2,500 IU’s of vitamin A and 250 IU’s of vitamin D per teaspoon.

Hi Jennifer,
If you were to take the FCLO capsules and HVBO liquid, you'd need to take 5 capsules a day to equate to half a teaspoon of cod liver oil, and quarter of a teaspoon of the HVBO liquid. Again, I'm not 100% sure that this is the optimum ratio to take these products in, but it's the same ratio as what is contained in their 'blend' products.

CLO allergy
written by Deborah, Jun 28 2011
I've tried to take FCLO several times now. The first time, all went well for a few days. I felt good. Then, I started coughing, really badly, bringing up tons of phlegm, every time I took a dose. The last dose I took, I started wheezing, so I stopped. The same thing has happened each subsequent time I've tried the FCLO, except that now the coughing happens immediately and the wheezing begins with the second or third dose. I thought that perhaps I could take the Blue Ice FCLO/HVBO mixture in capsules. I don't cough when I take it, but I do ache all over and I'm very fatigued. I'm assuming that I have some kind of allergy or sensitivity to the FCLO, which disappoints me greatly. Are there other varieties of fish liver oil that might have similar benefits, to which I might not be allergic? Are there any that you would recommend I try?
Thank you very much!

written by Priscilla P., Jun 21 2011
I just purchased Carlson's Cod Liver Oil 1,000mg capsules, which is listed in the "Good" section of your article. The directions on the bottle say to take 1 capsule up to 3 times per day at mealtime. Since your article recommends at least 10,000 IU of Vitamin A and 1,000 IU of Vitamin D, I have decided to take 4 capsules per day. This would amount to 10,000 Vitamin A and 1,600 Vitamin D. Is this safe since the EPA per capsule is 70mg and DHA per capsule is 80mg? I read somewhere in the comments that overdose of EPA should be avoided. How much is too much?

Also, should they be taken with meals as the directions say or should they all be taken together in the morning?

A question, and a contribution
written by Adrian Portell, Jun 15 2011
What a lot of information to take in and disseminate! I have been contemplating taking FCLO since reading Tim Ferriss' 'The Four Hour Body', and I am very grateful for the information contained in this article. I thought I might share the information I have figured out from the greenpastures website as far as cost of dose goes. All the following is based on an adult dose of half a teaspoon of FCLO per day. It is also based on buying products in bulk (12+ units), to get the cheapest price per unit, and does not take postage costs into account.

FCLO liquid: $0.35 per person per day
FCLO gel: $0.45 per person per day
FCLO capsules: $0.92 per person per day

If one is interested in combining with High Vitamin Butter Oil (as I am), then you can also consider their blend products. In order to still achieve the desired amount of FCLO:

Blend gel: $0.76 per person per day
Blend capsules: $1.46 per person per day

Since they also sell the butter oil, separately, you can mix and match. Assuming you want to maintain the same ratio of FCLO to HVBO:

HVBO liquid: $0.26 per person per day
HVBO capsules: $0.48 per person per day (assuming taking 2.5 capsules per day is too difficult, so instead just taking 2 capsules per day).

Please note that these results are NOT based on the serving sizes from the labels on the greenpastures products. They are based on getting half a teaspoon of FCLO per day, and a quarter teaspoon of HVBO.

So if you want the combination of FCLO and HVBO, your options are:
Cheapest: FCLO liquid and HVBO liquid: $0.61 per person per day
Palatable: FCLO caps and HVBO liquid: $1.18 per person per day
Easiest: blend caps: $1.46 per person per day

Also, I'd like to clear up a misconception from earlier posts regarding the amount of FCLO in the blend capsules. Each FCLO capsule contains 500mg of FCLO, and each blend capsule contains the same amount of FCLO, as the capsule is 750mg total, and 2/3 of this is 500mg (noting that the capsule is made up of 2/3 FCLO and 1/3 HVBO).

Now for my question:
I read an article today from mercola.com, about his recommendation for NOT taking cod liver oil, and specifically mentioning the Weston Price foundation. I'd really like to consolidate these two sources of information, so if there are any updated views on why either party may be wrong, or of a way to reconcile the two opinions, I would be very keen to hear. I know the Weston Price foundation places very high importance on ratios of Vitamin A to Vitamin D, but Dr Mercola seems to think that this ratio may still be vastly wrong. He also doesn't seem to make the distinction between fat soluble and non-fat soluble vitamin A, which may be what is leading to his conclusions about vitamin A toxicity. Am I misinterpreting this?
The article is at:
http://articles.mercola.com/sites/articles/archive/2008/12/23/important-cod-liver-oil-update.aspx

Feedback would be greatly appreciated, and I hope my above calculations are helpful!

this article says the benefits outweigh the risks
http://hubpages.com/hub/some-fish-oil-supplements-may-contain-pbc

Counter Argument Against the Suit

California's Prop 65 is a more conservative standard that is not in place across the whole country. In fact, the FDA (Federal Drug Administration) allows for a tolerance of 2 parts per million of PCB in fish which is higher than California's 90 nano-gram per day limit. Fish in general contains more PCB than fish oil supplements due to the fact that supplements go through a refining process.

The Council for Responsible Nutrition concludes by saying ...

"The bottom line is that consumers, whether they live in California or elsewhere, should continue to feel confident in the safety and efficacy of their fish oil supplements. This lawsuit does nothing to change the strong science supporting the many health benefits of fish oil, which range from cardiovascular health to cognitive development of infants and young children, and the very low thresholds of PCBs which apparently trigger a labeling requirement in California cannot be extrapolated to demonstrate any actual risks at those levels. The health benefits for fish oil far outweigh any suggested, and unsupported, risks."

I can't find anything more current than March 2010.

Amy ...Re fermented cod liver oil and taste
written by Chris, Apr 21 2011
Fermented cod liver is not going to go off because fermentation is quite specifically a method of preserving food and enriching its nutrients so it is very unlikely that your batch is rancid ...you are better off with fermented CLO for this reason as it is much more likely regular non-fermented liquid CLO is going to go off quickly.

I infact know a very sensitive individual who cannot tolerate regular cod liver oil but can tolerate Fermented. We think, due to fact that the regular liquid CLO is going off about a week after opening the bottle whereas the fermented one this doesn't happen. AND/OR it could also be that the fermented CLO is the only brand containing the natural vit A and D whereas the others have synthetic replacements. She can't seem to take the capsuled CLO either due to what the capsules are made off...but she is super sensitive though! Most people will be fine with capsule CLO.

If you do decide to take the regular CLO then capsules are better as they are less likely to go rancid compared with the liquid as they are not exposed to the air.

Carlson's is one of the WAPF recommmended brands and they have capsules, so you are probably fine with those. I use this interspersed with fermented CLO because they are cheaper and I can't always afford the fermented. But I do notice I have alot more energy when taking fermented cod liver oil.

I think there are alot of traditional foods we have simply become so unfamiliar with in our modern world that the tastes don't come naturally to us anymore. But it's worth the effort to make the changes for our own good health. I am quite used to taking the fermented CLO now and it is not a big problem but I did find it pretty foul to begin with.

But I'd never actually had them before, and the taste-paradigm my senses has become accustomed to told me these new foods were disgusting.

I guess I overpowered them with my mind, emboldened with the knowledge that these foods really were good for me. Now, I love--even crave--some of the stronger tastes. And I can't stand sweet foods! UGGGHHH.. Now THOSE make me want to vomit!!

One little trick that helps is to consume bitter foods. That really gets your bile activity ramped up to handle the rich tastes in alot of these fats. I juice dandilion greens with carrot juice, take Swedish Bitters, and make bitter herbal water and alcohol extracts too. They help the process enormously!

Confused on Blue Ice Dosage

After reading through all the comments on this page I'm still a bit confused. If I start a regimin of the Blue Ice Butter/Cod Liver Oil as an adult I should be taking approximately 1-1/3 teaspoons daily, correct?

re: To jobert
written by tslate, Jan 02 2010
IMHO: Basically you went from taking 1 tsp of CLO to 1/2 tsp of mix CLO/Butter oil, I don't think it's 50/50 but pretty close. So you went from 1 tsp to 1/4 or 1/3 tsp daily, 3-4 times less. I would say that 1 tsp is hardly enough to see dramatic changes in one week. If the inflammation goes down then you'd feel better. But the fermented kind may take more time to work and the only direct correlation to health I have seen is that it raises vitamin D levels in the blood better than straight CLO over time. So if you really want to find out then take equivalent amounts of each over time and then see. But really 1 teaspoon is a trivial amount for an older person trying to overcome issues, assuming not much else in your diet has changed.

In the study you refer to, the vast majority of pneumonia cases were caused by paraffin administered nasally. Apparently there were a few cases caused by cod liver oil, probably due to the baby choking on it or being given cod liver oil when lying down. If I ate or drank anything laying down I would choke too. Cod liver oil should be safe as long as those situations are avoided. Also we recommend waiting till about 4 months before starting cod liver oil.

Regarding Gino's comment and Green Pasture
written by Jill, Nov 30 2010
You might assume Green Pasture did not get the email if you sent your question via email (perhaps it got in their spam filter), or accidentally overlooked answering it. Mistakes happen. If you called and they're supposed to call back, again, it could have been a mistake.

I used the contact form on their website to ask a question yesterday, and Dave Wetzel responded within an hour asking me to call the next day (it was about returns). I called this morning and spoke to someone immediately who was very helpful.

Dosage confusion for nursing mom...
written by nikki, Nov 17 2010
Hi there, I have been taking Green pastures CLO all throughout my pregnancy as well as the 3 months after my son was born. After reading this article I am confused by the amout I should be consuming each day. I take 2 capsules of the fermented CLO. Is this correct or should I be taking more. I read up to 20 capsules, is that a day? Or did I misread something?? Please help! Many thanks...

alternative for CLO?
written by Vicki, Oct 22 2010
Hi, I am wondering about alternatives to CLO. My family has been taking the Twin Labs but we found out recently that I have an inflammatory response to cod (and several more generally healthy foods) via the Alcat test (alcat.com). Also, my son who is still nursing is still allergic to yeast and dairy, so our fats have been mainly lard, suet and olive oil. We also eat pastured eggs and liver sausage on a daily basis but I feel I need more vitA for nursing and my own healing.
I found some halibut liver oil online but read that the vitA content fluctuates widely in the species, and also do not know anything about its quality post-processing...
Since we have adopted the Nourishing Traditions diet, my son has outgrown his strong dog allergy already (hurray!) - thanks also to Dr. Cowan's book! :-)
Blessings and thanks for any suggestions.
Seven Seas CLO
written by Tim Boyd, Oct 21 2010
We are not real familiar with Seven Seas but looking at their website it appears that while the ratio is OK it suffers the same problems many other brands have. By the time the high-heat processing is done most of the vitamin A & D is gone and has to be added back. It also looks like they are using synthetic vitamins.
What about Seven Seas Cod Liver Oil?
written by Mike T, Oct 21 2010
I've been taking cod liver oil for years, but it's always been Seven Seas Cod Liver Oil, a British brand that's been around since the 1930s. The label says it has 400 IU of Vitamin D and 3500 IU of Vitamin A per teaspoon, which is well within the 1:10 ratio you recommend for conventional, nonfermented oil. Best of all, it costs about $7.00 for 450 ml, which is a tremendous bargain compared to other brands and to fish oil pills.

So why isn't this a recommended brand?

written by Claire West, Oct 12 2010
For a long time I used the regular clo from Green Pastures and then I used the fermented -- with no problems until about six months ago: the plain (no antioxidants) fermented smelled and tasted like sludge. I could not get it down. So next I tried the "orange oslo" and it always "repeats" the orange taste. I have read that any repeat indicates rancidity. Is this true?

"Fermented" or... rancid?
written by Igor, Oct 09 2010
What's the difference between a "fermented" oil and a rancid one? I can't wrap my head around that.

I would have thought that when it comes to fish liver oils, the fresher, the better. After all, extra virgin olive is probably stabler than cod liver oil, yet no one sells "fermented olive oil". In that context, we all would understand that "fermented" means rancid and that that oil would be best avoided.
Another reply to Jimmyv
written by Tim Boyd, Sep 21 2010
The royal blend includes x-factor butter oil which is pretty expensive stuff. Otherwise your math looks correct.
Tim Boyd's reply to jimmyv
written by jimmyv, Sep 21 2010
Hi Tim,

Those recommendations are on the bottles themselves, from the manufacturer (Green Pastures). Directions (for the royal blend) are to take 2 capsules, for a total of 1165A and 240D. In order to reach the levels recommended here in this article, one would need to take 16 capsules per day, or 480 per month. So for one person, that would be 4 bottles, or $200 per month. $400 per couple. Or I can take the blend of flavored liquid gel and triple the bottle's recommended dosage. That would be 1 bottle per month ($50 per person).

Seems to me that the capsules are inappropriately priced for the same product.

Cod Liver Oil / Butter Oil Blend and A&D doses
written by jimmyv, Sep 18 2010
So I am looking at getting the Green Pastures blend, but I'm confused by the serving suggestion and associated vitamin doses. The recommended liquid 2.5 ML dose (half teaspoon) provides 3000 IU Vitamin A and 600 IU Vitamin D. But in capsule form, the recommended dose is 2 capsules and the vitamin content is listed at only 1165 IU Vitamin A and 240 IU Vitamin D per serving. This is a huge difference and would then lead me to wonder, why isn't the recommended dose for the capsules simply 4 capsules instead of 2, providing 2330 A and 480 D? I am just trying to figure out what to purchase for next time. Am I thinking correctly on this? Also please note that I have read the articles above in full, and see that the recommended doses detailed above are 9500 A and 1950 D. This only adds a bit to my confusion as to why the recommended doses on the bottles are so much lower. Sorry for so many questions smilies/cry.gif

Swansons Double Strength Cod Liver Oil does not qualify as what we consider high-vitamin cod liver oil. You would have to take 4 capsules to get the vitamin A & D we recommend, which would cause possible overdose of EPA.

Carlson's Norweigan Lemon Flavored Cod Liver Oil
written by Carolyn Graff, Sep 08 2010
this is from Sally:

Please read our information on cod liver oil. We do NOT recommend Carlsons, as it contains mostly vitamin A and little vitamin D. Nor do we recommend fish oil, as it is invariably rancid (they boil it at 230 degrees for several hours!!) and also will overload with EPA, which is not desirable. For pregnancy and lactation, we recommend 2 teaspoons fermented cod liver oil in the context of a diet rich in butter, egg yolks and organ meats. For a maintenance dose, 1 teaspoon per day, all year, unless you are a lifeguard and getting huge amounts of vitamin D from the sun.
Capsules just one-tenth of a teaspoon?
written by Carolyn M. Graff, Sep 08 2010
you can take either 1/2 teaspoon or a full teaspoon of the fermented CLO.

from the article above:
"Please note that the fermented cod liver oil contains many co-factors that may enhance the body's uptake and usage of vitamins A and D; in fact, many have reported results equivalent to those obtained from high-vitamin cod liver oil with half the recommended dose, that is ¼ teaspoon or 1.25 mL for children age 3 months to 12 years; ½ teaspoon or 5 capsules for children over 12 years and adults; and 1 teaspoon or 10 capsules for pregnant and nursing women."
Capsules just one-tenth of a teaspoon?
written by jimmyv, Sep 08 2010
Hey but wait! I take the liquid Oslo Orange and liquid unflavored butter oil. The directions recommend only half teaspoon per day of each. Am I supposed to be taking 1 full teaspoon of the Cod liver Oil? Man I sure hope not. I've been filling the other half of the spoonful with pure lemon juice concentrate. Even with the "Oslo Orange flavor", I am never excited to take that CLO. The butter oil, on the other hand, is very pleasant, and I definitely take it after the CLO to end on that flavor instead. I was thinking of getting the capsules next but I may have to look into the cost now.

Thank you for such an extensive report on the cod liver oils. I have been using the green pasture CLO for a while now keeping the dose at around 4 capsules/day.

But your text above says I should be taking 10(!). Is it indeed accurate that one teaspoon equals 10 capsules? That would make the capsules considerably more expensive than the liquid (a bottle of capsules would last just 12 days per person).

The bottle label itself recommends 2 servings per day. Could you please confirm I should indeed be taking 10 to reach the 10.000 A and 1000 D?

Hi... don't mean to be 'pesty'. I just want to make sure I get this right before purchasing the wrong product. I am eating a diet rich in eggs, butterfat, and fish. Plus I take "NUTRILITE® Vitamin D3 2000 IU Plus K2". Is it possible that I am getting enough vitamin A from natural food sources? If yes, does this mean that if I took... say... your first recommended product on the best list, the "Green Pasture Products: Blue Ice High-Vitamin Fermented Cod Liver Oil" that I might have too high an intake of vitamin A & D? Could this possibly be a game changer where you would then make a different recommendation for me?

Green Pasture does not subject their cod liver oil to any high heat processing which destroys vitamin content. That is unique so far in the industry. So fermented cod liver oil is much higher without adding synthetic vitamins.
synthetic vitamin A?
written by Ann, Aug 20 2010
The Nordic Naturals website claims that the amount of vitamin A in their cod liver oil is the naturally occurring amount, and that other brands that contain more vitamin A have had synthetic vitamin A added.

Vitamin D and heavy metals
written by Carolyn Graff, Jul 01 2010
this is from Chris Masterjohn:
If you live in Hawaii and are outside often and begin using one serving per day of high-vitamin cod liver oil, most of your vitamin D will be coming from the sun. I therefore do not think the cod liver oil will by itself meaningfully affect your vitamin D levels in that case, and it will provide vitamin A, which is important to balance all the vitamin D you are getting from the sun. So I think a serving per day of high-vitamin cod liver oil should be beneficial.

this is from Dave at Green Pasture:
All our products are third-party tested beyond what the law requires. We test heavy metals and PCB's. In 10+ years of testing cod liver oils, I have never seen a positive test for inorganic heavy metals such as mercury.

Would we be getting too much vit D if we start using blue ice high vitamin fermented CLO (we live in Hawaii and go to the beach and are outside often)?

There is nothing stating that a third party tests this product and certifies it free from any heavy metals. I have contacted the company via e-mail but received no response to this question. We are currently using Nordic Naturals which I know is safe in terms of no metals in it, but not a good choice otherwise. Can anyone help with this concern?

CLO w High Vitamin Butter Oil
written by Carolyn Graff, May 24 2010
this is from Chris Masterjohn:
I think the digestive problems are likely due to problems digesting
the long-chain PUFAs. Did your son use the fermented product or
the original product? Some people have reported digesting the
fermented product better. The depression could, perhaps, be a result
of a) not tolerating the product correctly (most apparently in this
case, by not being able to digest it), b) too much EPA if the diet is
otherwise poor in sources of AA such as butterfat or liver, or c)
imbalances of one or the other fat-soluble vitamin. There could, of
course, be other causes, but I would address them in that order. If
the original product is being used, try the fermented product. If the
fermented product is being used, try changing when it is consumed
(e.g. with or without meals) or adding foods or supplements to help
with fat digestion (e.g. enzymes or Swedish bitters).
Vitamins/minerals MUST be taken with food
written by LP, May 22 2010
I don't see this mentioned anywhere here. Vitamin and mineral supplements MUST be taken with food, to be effective. And with enough water too.

I have come across too many people who take vit/min supplements between meals or, worse, on an empty stomach. If you do this, you are not only not getting any benefits from the nutrients but also wasting your money.

One example is a young 27yo woman I know, a ballet teacher (presumably she gets enough exercise), who suffers from chronic backache and sinusitis. Also, ALL of her fingernails are completely covered with white spots, a sign of severe zinc deficiency. When questioned, she said her regimen is to take a large CalMagZinc tablet with a glass of water in the morning before she rushes off to work. Yes, on an empty stomach, without any food at all!

Ideally, vit/min supplements should be taken just after meals. Each meal should also be accompanied with at least 2 (or better 3) glasses of water and/or healthy liquids consumed within 3 hours of the meal. This is to help with proper digestion of the food and supplements.

BTW, just for info, I have tried all kinds of vit/min supplements over the last 30 years. Time-release supplements do NOT work. The vits/mins need to be mixed with the food and liquids in the stomach before the 'chyme' passes into the duodenum, the first part of the small intestine, when the digestive enzymes get to work on it. Vits/mins released in the large intestines 6-8 hours later is useless.

something in one of the two supplements, but I think they'd have to
use trial and error to decide what is causing the problem. Certainly
if this continues for a few more days they should try removing one or

It would not be good to take 12 capsules of Carlson's per day on an ongoing basis. You would be getting too many polyunsaturated oils. It would be better to get the A and D from the fermented cod liver oil (about 2 teaspoons) in order to minimize the intake of polyunsaturated oils.

Hi Carolyn.

I have recommended to him that he take Carlson's CLO for it's additional benefit of Vitamin A - and this is the product I take and love. To get an equivalent high dose of EPA & DHA from CLO, this would mean 12 capsules a day, which is 24,000 IU of Vitamin A. Would this level of Vitamin A be safe for him to take on an ongoing basis?

Do you have any insight into why this is? Should I have taken a larger dose of the fermented kind, even though the label recommended 1/2 teaspoon per day? Thanks!

"But since many people cannot obtain or cannot afford the fermented cod liver oil, we recommend in the 'good' category (rather than the 'best' category), cod liver oil to which synthetic vitamins A and D have been added in the right proportions."

These blends are fine to take. A dose that provides about 10,000 IU of vitamin A daily is recommended for adults.

I don't see any of the Fermented Cod Liver Oil / Raw High Vitamin Butter Oil blends recommended. Do you feel that it is better to take these separately? If you feel that they are good, what dosages would you recommend?

this is from Sally:
Coconut oil has many health properties but it does not contain the fat soluble activators A and D that are so valuable for nutrient assimilation.

Will coconut oil assist in the absorption of the nutrients in cod liver oil and would it make a good substitute for high vitamin butter oil?
Pregnancy
written by Carolyn Graff, Mar 26 2010
from this page:
http://www.westonaprice.org/Co...ions.html

Pregnant and nursing women: A dose of cod liver oil that provides about 20,000 IU vitamin A daily, obtained from 4 teaspoons regular cod liver oil or 2 teaspoons high-vitamin cod liver oil.

So, you would need to take 4 teaspoons of the Twin Labs CLO.
CAN YOU COOK WITH COD LIVER OIL VRS A VEG OR CANOLA OIL?

You can not cook with cod liver oil due to the polyunsaturated fats it contains. Polyunsaturated oils should never be heated.

Hi, I am about 8 weeks pregnant and I was taking fish oil, due to the article from Dr. Mercola, for the last several weeks. I ran out and came across your article. We are unable to afford the fermented oil, but I am wondering how much of the Twinlab Norwegian cod liver oil I should take.

Thank you so much for all the information,

what about the harvesting practices for the fish oil? I heard ocean scientist Sylvia Earl speak about fish oil harvesting practices that are harmful to our ocean. They scrape the ocean bottom?
I have gone to flax seed, which doesn't work as efficiently for me as the fish oil. Would love information about safe harvesting practices so I can go back to fish oil. Do you have any information? (Many companies will say they harvest "sustainably" but they are speaking specifically about the number of fish they harvest, not the other effects of their practice.)

(1) I am undecided on which to buy from Radiant. Is the fermented or the Premier Quantum Norwegian Cod Liver Oil
better for children above 7 years old.
***The fermented is better for everyone.

(2) Is it necessary to also take it with the butter oil (as this is quite expensive)? If not, which is the alternative way to take the cod liver oil for better assimilation?
***If you can't afford the butter oil, take the CLO with deep yellow raw grassfed butter from the spring or fall.

Can't find Premier High-Vitamin Cod Liver Oil in their website.
***They are the same.

2) This is listed in the 'best' category?
***Yes, in the best category.

3)Dose for children below 12 is half teaspoon?

CLO with synthetic vs. natural vitamins

The Radiant Life Premier High-Vitamin Cod Liver Oil contains natural vitamins too (along with the fermented cod liver oil). This is listed in the 'best' category.
Comment from Sally Fallon on CLO with synthetic vitamins
written by Jill Nienhiser, Mar 03 2010
Sally asked me to post the following in response to some of the questions above asking about brands which replace naturally occurring vitamins with synthetic: "We have consistently pointed out that the vitamins in all but one brand of cod liver oil are synthetic. Only the fermented cod liver oil made in the United States contains the original natural vitamins. Every other brand of cod liver oil is definitely a compromise. But since many people cannot obtain or cannot afford the fermented cod liver oil, we recommend in the 'good' category (rather than the 'best' category), cod liver oil to which synthetic vitamins A and D have been added in the right proportions."

Hello! Have you looked into Premier Research Labs and their Cod Liver Oil as well as many other supplements of highest quality? I haven't seen them listed anywhere on your site and I think you may find this company to be a fantastic find. I have been using their products for several years now and find them to be of highest quality I have found so far. They are 100% excipient free... no silica in their cod liver oil either.

Why not Salmon Oil????
written by dan, Feb 22 2010
Hello all,

I currently use salmon oil instead of cod liver oil, and I wondering why more people don't as well? Is there a unique benefit to cod liver oil, that salmon oil does not contain? If so, could someone enlighten me as to the difference? Just for comparison purposes, I use Vital Choice's 1,000mg Sockeye Salmon Oil. It is whole, unrefined, certified pure, and comes from wild Alaskan salmon. It contains (per serving): 240mgs EPA, 220 DHA, 340 IU of vitamin D, and 2,060 IU of vitamin A. The A & D are natural, not added. It seems comparable to the cod liver oils listed above, and I have a little more faith in the source. Am I missing something here? Thanks all.

Oxidation is the key.
written by Stuart Tomc, Jan 08 2010
Unfortunatly this review ignores the fact that marine based Omega 3 supplemnts must have very low levles of oxidative rancidity. Wild fish is not fremented, it's fresh, and fresh fish has the power. We need to understand that rancidity in fish oil can be tested and is the best guideline for recomendations. I am a Dr. Price fan and he would agree! http://www.ifosprogram.com/IFOS/default.aspx

I am very confused about conflicting information on this site regarding Vitamin D. I just read in a different article here that Vit. D can be toxic to some people in doses as low as 200-400 IU's, but here such a higher dose is recommended. Should I not supplement with cod liver oil unless a D deficiency has been identified?
Vitamin D
written by James, Sep 08 2009
Above you have stated that 1 teaspoon of high-vitamin fermented cod liver oil contains 9500 IU vitamin A and 1950 IU vitamin D, a ratio of about 5:1. David Wetzel; however the manufacturer of the oil states in his April 30, 2009 update that the fermented oil contains 4,000 - 9,000 IU vitamin A per teaspoon and 3,000 - 4,000 IU vitamin D. Which is correct?
