NOW Foods Niacin 500mg Double Strength Flush-Free 180 Veg Caps

NOW® Flush-Free Niacin Double Strength delivers 500 mg of vitamin B-3 as inositol hexanicotinate — a molecule made of six niacin units bound to a single inositol molecule. Because the niacin is released slowly as the body gradually breaks the compound down, this form provides the benefits of vitamin B-3 while avoiding the warm, tingling flush that standard niacin so often causes. Niacin is an essential B-vitamin that supports healthy energy metabolism and overall wellness, and this double-strength version offers a higher potency per capsule.*
