Overview

Now Foods Flush-Free Niacin is a dietary supplement built around inositol hexanicotinate, a form of niacin (vitamin B-3) designed to deliver niacin activity in a slower, more gradual way. Each serving provides 500 mg of niacin from 549 mg of inositol hexanicotinate, along with 120 mg of inositol. The formula is intended to provide the benefits associated with niacin while avoiding the characteristic flush that many people experience with higher dose niacin supplements.

This product uses a non flushing source of niacin that is described as being slowly broken down in the body. That gradual conversion is what distinguishes it from more basic niacin supplements, since it is meant to reduce the common flushing response while still supplying niacin. The supplement is offered in vegetarian capsules and fits into Now Foods’ broader nutritional health line.

The product is also labeled non GMO, vegetarian/vegan, kosher, and GMP quality assured. It is made and quality tested in the USA with globally sourced ingredients.
