Details: Methyl cobalamin (methyl b-12) is better absorbed and retained than other forms of b12 (e.g., cyan cobalamin). Methyl b-12 supports nerve tissue and brain cells, promotes better sleep and recycles (via methylation) homocysteine, an oxidizing metabolite, back into the amino acid methionine. Also, vegetarians/vegans often require b12 supplementation. These statements have not been evaluated by the food and drug administration.
