Solgar Methycobalamin Vitamin B12 5000 mcg Sublingual Nuggets contains a body-ready, active form of Vitamin B12. 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 the predominant and active form found in the body. The "body-ready" Vitamin B12 in this formula is offered in a convenient nugget dosage form which is also suitable for vegan. Shift workers, college students, mothers and the elderly may use this supplement to support energy metabolism.
