General Statements: All Other Content

Vitamin B-12 is required for nerve and brain health, and for healthy red blood cells. It also works together with folate to maintain normal levels of homocysteine. Coenzyme supplementation reduces the body’s need to synthesize the active forms of vitamin B-12 from the synthetic form, cyanocobalamin.
