Product Overview

  • A Dietary Supplement
  • Vegetarian Formula

Inositol Hexanicotinate is a stable, non-flushing source of Niacin. This superior source of Niacin works to reduce the common "niacin-flush" problems associated with high doses of Niacin supplements.

Niacin (Vitamin B-3) is an essential B-vitamin necessary for good health. Many Niacin supplements cause a temporary Niacin flush or tingling red rash on the skin when taken in large doses. This flush-free Niacin is formulated to avoid such reactions.

Suggested Use

As a dietary supplement, take 1 Vcap daily as needed, with a meal; or take as directed by your health practitioner. Consider taking this product in combination with NOW B-50 Complex, D-Ribose and Sytrinol.

Other Ingredients

Cellulose (capsule), stearic acid (vegetable source), magnesium stearate (vegetable source), rice flour and silica.

Contains no sugar, salt, yeast, wheat, gluten, soy, milk, egg, shellfish or preservatives.

Vegetarian/vegan product.


Caution: Not to be used by pregnant/lactating women or those with liver problems, stomach ulcers or diabetes unless recommended by your healthcare practitioner.

Store in a cool, dry place.

No side effects, in fact no effects whatsoever

Posted by Reviewer1579877 on Jul 02, 2015

This product is a joke. This is not really niacin and does not have the benefits that niacin is supposed to have. You need the time release or immediate release nicotinic acid form of Niacin in order to get the cholesterol and tri-glyceride benefits. You will almost certainly get the flushes but that, if bearable, will be your indication that you have the real McCoy and that it is doing its job. I wasted my money on this one before doing my research.

Best Flush-Free Niacin EVER!!

Posted by Reviewer2782741 on May 01, 2014

I've tried other brands of flush-free niacin, but Now Foods brand works better than any of the others. I take 3,000.00 mg./day, so I really need the flush free. Even at such a high dose, I NEVER have flushing of any kind. I highly recommend Now Foods flush-free niacin.
