## Overview

NOW Foods Niacin 500 mg offers a potent, flush-free vitamin B3 supplement in vegan capsules, backed by rigorous GMP certification and third-party testing. Designed for adults seeking effective nutritional support without the typical niacin flush, this double strength formula delivers sustained release for optimal absorption and brain health.

## Description

Double Strength Flush-Free 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. This product has twice the niacin (500 mg per capsule) as in our regular strength product (250 mg per capsule). Natural color variation may occur in this product.
