About this product
Double StrengthNutritional HealthNon-GMOA Dietary SupplementVegetarian/VeganKosher VitaminsFamily Owned Since 1968Quality Assured GMPNiacin (Vitamin B-3) is an essential B-complex vitamin. Flush-free niacin contains inositol hexanicotinate, a form of niacin that consists of six molecules of niacin linked to a single inositol molecule. It is slowly broken down in the body to yield free niacin and inositol. This gradual release of niacin allows for true niacin activity without the characteristic niacin flush that many people cannot tolerate.Inositol hexanicotinate is a stable, non-flushing source of niacin. This superior source of niacin works to reduce the common "niacin-flush" problems associated with high doses of niacin supplements.This product has twice the niacin (500 mg per capsule) as in our regular strength product (250 mg per capsule).
