Vitamin B

The B group, with the bioactive forms stocked wherever the manufacturer makes them. That distinction is the main reason people come to this page: methylcobalamin rather than cyanocobalamin for B12, and methylfolate or folinic acid rather than folic acid — these are the forms the body uses directly.

You will also find choline, inositol and TMG on this page. They are not B vitamins — they are vitamin-like methyl donors, shelved here by long-standing convention because they are taken in the same context. Choline has its own page under Minerals. Parent page: Vitamins.
