Good for nerves and good for arthritis, but not for cholesterol.

Posted by Reviewer1097755 on Jun 12, 2011 | Verified Purchase

Very effective for calming nerves and anxiety, without inducing fatigue or dulling one's mind (works at doses from 300 mg to 600 mg three times a day). It also works well in reducing arthritic pain (at doses as low as 300 mg once a day). But, people should know that this form of vitamin B3 does not effect cholesterol levels--for that, you need the Niacin form.

Good B3

Posted by 5109157552070576586 on Oct 15, 2014 | Verified Purchase

I use it occasionally when I need a relative low dose of Niacinamide. Works as advertised.

Gentle on stomach, doesn't raise blood sugar

Posted by KentuckyWildcat on Jan 20, 2017 | Verified Purchase

Regular flushing niacin is very acidic and can upset your stomach, plus it can raise blood sugar, especially in higher doses. Taking niacin as niacinamide avoids those problems. Niacin (vitamin B3) will do different things and have different effects in the body depending on what form is used. I use this niacinamide to help synthesize NAD enzymes and also as a GABA agonist.

Excellent service with my order, good pricing. The product is fine and I was pleased that it was not gel caps. It's early to tell whether the product is accomplishing what I want to accomplish, but I have no reason to believe that it won't.
