Natural Factors, Vitamin B12 Cyanocobalamin 1000 mcg, Supports Energy and Red Blood Cell Production, 60 tablets (60 servings)

Vitamin B12 (Cyanocobalamin) is a water-soluble vitamin necessary for energy production; for nervous system function as it is needed to produce myelin, the fatty substance that forms a protective sheath around nerves; for the production of acetylcholine, a neurotransmitter that helps with memory and learning; for the synthesis of red blood cells; for producing the genetic materials, DNA and RNA. Vitamin B12 is primarily in animal-source foods and may be deficient in strict vegetarian diets. Vitamin B12 works with folic acid to control homocysteine levels.
