we need adequate methionine. After each methylation reaction, however, methionine generates homocysteine. Recycling
homocysteine back to methioinine is important both to prevent cardiovascular disease and to support the methylation
process. This requires vitamin B and folate. At high concentrations of methionine, for example, in the hours after we eat a
