Vitamin B12 aids in the formation of red blood cells and is critical for brain and nervous system function.† Methylcobalamin is a body-ready form with metabolic benefits that may not be provided by other forms of vitamin B12. Although cyanocobalamin is the most commonly used form of vitamin B12 in dietary supplements, it must be converted by enzymes into an active coenzyme form to be useful. Nutritional inadequacies, enzyme defects, and tissue abnormalities can reduce the body’s ability to synthesize the active forms of B12. This active form is reliably absorbed and utilized by the body. These high-potency, fast-dissolving tablets contain no artificial sweeteners and supply 5 mg of B12. Tablets should be dissolved in the mouth and swallowed.
