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

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.

Good Product

This is a good product, but I have done some research and found that niacin (the flushing kind) has more benefits and can help to flush out plaque from your arteries, so I have chosen to purchase niacin now.

I take this in combination w/ Now E , Now A and pantothenic acid in powder form to boost immunity as prescribed by by naturopath. I have taken it 3x a day and the incidence of an auto-immune rash has not returned for 4 mos. .

I actually first looked into using this for ringworm rash. Turns out it can assist with anxiety and depression. My daughter suffers with anxiety, and she has noticed an improvement. She says it doesn't take it away, it just makes it manageable. She takes 1,000 mg every night. As for myself, I have noticed a significant lessening of my ringworm. I only take 500 mg. We will continue to use this!
