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

I use this to DIY a body lotion for whitening. It works very well to moisturize dry skin and fade pigmentation. Being using it for a while and will not stop using it. I do wish Now Foods carry the pure powder with additives though.

Thanks for your feedback!
