Niacin (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.Natural color variation may occur in this product.'Double Strength 'Flush-Free'Dietary ConsiderationsVegetarianVegan'Serving Size:1 Vegetable Capsule'Servings Per Container:90'Amount Per ServingNiacin (Vitamin B-3) (from 640 of Inositol Hexanicotinate)500 mgInositol (from 640 of Inostiol Hexanicotinate)135 mg'Other Ingredients:Cellulose (capsule), stearic acid (vegetable source), magnesium stearate (vegetable source), rice flour, silica'Suggested Usage: Take 1 capsule daily as needed, with a meal.Not manufactured with wheat, gluten, soy, milk, egg, fish, shellfish or tree nut ingredients.
