NOW's Flush-Free Niacin delivers 500 mg of niacin (vitamin B-3) as inositol hexanicotinate, a form that releases gradually so it avoids the warm, flushing sensation associated with standard niacin. Each capsule also supplies 135 mg of inositol.
The vegetable capsules are made with hypromellose, stearic acid, rice flour, and silicon dioxide. NOW suggests one capsule daily with a meal from this 90-capsule bottle.
