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.

Have ordered niacinamide from jarrow formulas and this one from Now foods. This is excellent product, personally i think is better than the other one, but that's for me. Worth the money.

Thanks for your feedback!

Great Product.

I mostly use Now Foods supplements. I find them very effective for whatever I use them for. This product is no diffeent. A family member uses this as part of his protocol for an over-methylation problem. This works without giving a niacin flush.

Thanks for your feedback!

Didn't feel anything.
