Product Overview

  • Vitamin B-3, No Flush
  • Non-GMO
  • A Dietary Supplement
  • Vitamins
  • Family Owned Since 1968
  • GMP Quality Assured

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.


Store in a cool, dry place after opening.

Caution: For adults only. Consult physician if pregnant/nursing, taking medication, or have a medical condition (liver problems, stomach ulcers, diabetes, gout, etc.). Keep out of reach of children.

Now Foods Niacinamide, 500 mg., 100 Capsules

Posted by Reviewer1404523 on May 16, 2008

I take niacinamide at night to help me relax and sleep. I also take it in the day to control my fearfulness when talking over the phone. It allows my voice to come out in a normal fashion, controlling my selective mutism. It works as well as Librium.

Stress Relief!

Posted by Reviewer2052996 on Jan 31, 2012

I find this extremely relaxing without making you drowsy during the day. Take the edge right off my stress at two capsules with each meal. Helps insure a good night’s sleep, too. I would give this six stars if I could.

Niacinamide 500mg

Posted by Reviewer2616084 on Nov 08, 2010

So far so very good. I know we have to be on them for a little while before we feel the full effects but there have been no side effects and my husband who has parkinson's and dementia seems to be a lot more cheerful. We think your products are excellent and so much cheaper than here in Australia
