Each gelatin capsule contains 25 mg. niacin (Vitamin B3).
Niacin is a member of the Vitamin B complex and is often referred to as Vitamin B3. Since it is water-soluble, it is not stored in the body, and therefore must be regularly replenished through the diet or supplementation. Niacin is needed for several functions in the body, including energy production, metabolism and nervous system function.*
