Methylcobalamin (mecobalamin) is the preferred form of vitamin B12 and exerts benefits well beyond those of other forms of cobalamin. Methylcobalamin is delivered much better to nerve tissues where it functions in accelerating transmethylation reactions in the manufacture of nucleic acids, neutrotransmitters and phospholipids.
