Product Overview


  • Dietary Supplement
  • Vitamin B-3

Niacin plays an essential role in the activities of various enzymes involved in the metabolism of carbohydrates and fats, the functioning of the nervous system and digestive systems, the manufacturing of sex hormones, and the maintenance of healthy skin.

Suggested Use

1 tablet daily with a meal.

Other Ingredients

Sorbitol, stearic acid, modified cellulose gum and magnesium stearate.

Suitable for vegetarians. Contains no yeast, dairy, egg, gluten, soy or wheat. Contains no sugar, starch, salt, preservatives, or artificial color, flavor or fragrance.


Caution: If you are pregnant, may become pregnant, breastfeeding, or have diabetes, liver dysfunctions or ulcers, consult your health care professional before using this product.

Note: Niacin may cause temporary flushing, tingling, skin reddening, and sensations of heat, especially if taken on an empty stomach. This is a natural and harmless reaction. Niacin 250 is time released to minimize the intensity of the flushing response, which varies from person to person.

Do not use if either tamper-evident seal is broken or missing. Keep out of the reach of children.

Niacin is better than Statin with no side effect

Posted by Reviewer2647046 on Jan 19, 2012

Niacin really works! It increases HDL, lowers BP & improves circulation all over especially to my legs & feet. Unless you want a surprising tingly Niacin flush, best to start with half a tab on a full stomach. Excellent potent product. Will take Niacin for life. Could do with an economy size like 360 or 500 tabs.

These tablets cause quite a bit of flushing. Time release capsules may be a better choice.

...almost... flush-free

Posted by Reviewer3343289 on Mar 02, 2009

Although touted as "timed release to minimize flushing" this only seems to work well for me if taken right after (not before) a meal. In that case, flushing is quite minimal.

Horrible flushing

Posted by Reviewer1022335 on Feb 24, 2009

I've been taking this same niacin for years, waiting for the flushing to subside or stop since it is a Timed Release Niacin. This has not happened yet. I experience horrible head throbbing and rash producing flushing. I'm looking for a different extended release niacin.
