Methylcobalamin ULTRA is an ultra-highdose formulation of methylcobalamin, the neurologically active coenzyme form of vitamin B12. Methylcobalamin supports the healthy structure and functioning of the brain and nervous system. Studies show that a person may not have optimal methylcobalamin for proper neurological function, even when vitamin B12 intake and status is normal. This higher-dose formulation is for persons for whom research supports supplementation at higher levels than in our standard Methylcobalamin formulation.
