## Overview

NOW Foods Niacin 500 mg delivers a potent, flush-free vitamin B3 boost using inositol hexanicotinate for gradual release. Perfect for professionals seeking effective, clean supplements, it’s vegan, gluten-free, and non-GMO, made by a trusted family-owned company since 1968.

## 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.
