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.

***Use this coupon VUD014 and save $5 on your first iHerb order!*** I've been taking Niacin for a few years now. Tried different brands. Source Naturals was very good! But last time when I wanted to reorder, they were out of stock, so I ordered Solgar. It has the best quality product! It's worth the price. I get the 500 mg, large (250 caps) bottle, which lasts a very long time. Capsules absorb much better than pills. No-Flush works best for me. I flushed A LOT on the other one and turned bright magenta ;) I take 1 cap first thing in the morning with a glass of water. I feel it kicking in within minutes! Energy levels increase, it helps me to wake up faster and start my day with mental clarity & sharpness!!! Highly recommend!

Niacin is better than Statin with no side effect

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.

Thanks for your feedback!

**Read carefully - this is time released!

I wanted a good, NON time-released B3 (the time-released version can put more strain on the liver, and since I'm doing a detox, that seemed counter-productive). Unfortunately, the product details didn't read 'time-release', and I didn't think to zoom in on the label to double-check, so these may be good, but I'm going to have to turf them....sad.....
