Methylcobalamin is the active, coenzyme form of Vitamin B12. While the body can readily absorb Vitamin B12 as cobalamin, it must further convert it to a coenzyme form, methylcobalamin, to become metabolically active. In this form, it is bioidentical to one of the two active forms found in the body. The œbody-ready� Vitamin B12 in this formula is offered in a convenient nugget dosage form which is also suitable for vegans.
