Niacinamide and Niacin are two different forms of Vitamin B-3. Niacinamide does not cause a Niacin flush.

Niacinamide (Vitamin B-3) is a form of Niacin, a water soluble B-Vitamin. It is a derivative of Niacin that does not cause the "flush" normally associated with taking high doses of Niacin. Niacinamide is readily converted into the bioactive forms of Niacin, NAD+, NADH, NADP, and NADPH, which are vital cofactors in cellular energy production and are critical for the maintenance of DNA stability.

Suggested Use

Take 1 capsule daily with a meal.

Other Ingredients

Gelatin (capsule) and magnesium stearate (vegetable source).

Not manufactured with wheat, gluten, soy, milk egg, fish, shellfish, or tree nut ingredients. Produced in a GMP facility that processes other ingredients containing these allergens.

It does give me a bit of a rush

Posted by Reviewer2635763 on Jun 05, 2016

As the title says, it still does give me a bit of a rush. Not as bad as a full blown niacin flush. The alertness and concentration factor change is noticeable.
