In his book The Heart Revolution, Dr. Kilmer S. McCull says that to cut one’s risk of heart disease, we need to use vitamins B6, folic acid and B12. He says that the marker for heart disease or potential heart disease is homocysteine.
Vitamin B-12 (Cobalamin)
Women who eat steak, rich in vitamin B-12, during the first three months of their pregnancy are up to eight times more likely to have babies who cry less, according to a new study published in the journal Early Human Development.
Vitamin B-12 is the largest and most complex of all the vitamins. It is unique among vitamins in that it contains a metal ion, cobalt. For this reason cobalamin is the term used to refer to compounds having B-12 activity. Methylcobalamin and 5-deoxyadenosyl cobalamin are the forms of vitamin B-12 used in the human body (1). The form of cobalamin used in most supplements, cyanocobalamin, is readily converted to 5-deoxyadenosyl and methylcobalamin.
