Vitamin B12 helps produce red blood cells, maintain good health, and prevent B12 deficiency states such as pernicious anemia.* Methylcobalamin and dibencozide are coenzyme forms of vitamin B12 whereas cyanocobalamin must be converted to its metabolically active coenzyme form in a two-step process. Taking methylcobalamin and/or dibencozide allows for greater absorption and bioavailability than noncoenzyme forms. Natural Factors BioCoenzymated Methylcobalamin & Dibencozide formula is offered in a convenient one-per-day chewable form.
