Product Overview


  • Dietary Supplement
  • B-3 for Energy & Cardiovascular Health

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 cholesterol, and the maintenance of healthy skin. Inositol hexanicotinate functions as niacin without the characteristic "flush".

Suggested Use

1 tablet daily.

Wrong product for me

Posted by iHerb Customer on May 19 2017 | Verified Purchase

I was wanting to use Niacin to lower my cholesterol. No-Flush Niacin isn't suitable for this. I threw this product out and purchased a flushing version instead.

Thanks for your feedback!

Keeping the circulation going at night

Posted by iHerb Customer on February 2 2017 | Verified Purchase

I wake up with cold feet that are numb and found that this product helps. I've been taking it for several months. This product is from Inositol jexanicotiinate that functions like niacin without the flush feeling. I once took a vitamin with niacin and thought I was having a heart attack. Whosh! So I appreciate this rendition since I take it at night before I go to bed.
