Niacin (Vitamin B-3) is an essential B-vitamin necessary for good health. Many Niacin supplements cause a temporary Niacin flush or tingling red rash on the skin when taken in large doses. This flush-free Niacin if formulated to avoid such reactions.

Inositol Hexanicotinate is a stable, non-flushing source of Niacin. This superior source of Niacin works to reduce the common "niacin-flush" problems associated with high doses of Niacin supplements.

Suggested Use

As a dietary supplement, take 1 Vcap daily as needed, preferably with meals; or take as directed by your health practitioner. Consider taking this product in combination with NOW B-50 Complex, D-Ribose and Sytrinol.

Other Ingredients

Cellulose (capsule), stearic acid (vegetable source), magnesium stearate (vegetable source), rice flour and silica.

Contains no sugar, salt, yeast, wheat, gluten, soy, milk, egg, shellfish or preservatives.


Caution: Not to be used by pregnant/lactating women or those with liver problems, stomach ulcers or diabetes unless recommended by your healthcare practitioner.

iHerb Customer Reviews

Could be a good brand but check out all possibilities first

Posted by HealthyLiving4Me on Dec 11, 2015

I have taken this product and have discontinued until I see my doctor as information I have discovered indicates that niacin (not necessarily this product) can raise blood sugar which could be an issue for type 2 diabetes. Also, I have recently been very itchy all over but I am unsure if it's related to this product or not at this stage. I will update this rating at a later time.

Take Niacin to raise HDL and lower triclycerides !!

Posted by Sickness-ELIMINATOR on Aug 11, 2013

I have high triglycerides and low HDL. Now Foods 500mg Niacin is the best treatment for lowering Triglycerides and raising HDL. Since niacin is not a patentable pharmaceutical product, physicians are many times not aware of the value of treating this condition with niacin. . . . . You can find other products I use on my Page! I use only products that have Scientifically Proven benefits.

did not work in lowering cholestrol

Posted by Reviewer2227545 on Dec 15, 2012

Tried this product and other flush free in an attempt to lower my husband's and my mother's cholestrol. My husband was taking 6/day. For them both it did nothing. BUT when I switched them to the regular niacin (the kind that makes you flush) - the results were more than magnificant. Total down, HDL up, LDL down, triglyclerides down. Start low - best to use tablets first so you can cut in half and move up. I gave my hubby too much and his cholestrol went down to 150. He now takes about 1/2 of what he used to. This was all with the regular niacin. As I said we had no results with the flush free.
