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

Posted by Reviewer1097755 on Jun 12, 2011

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

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

Husband objected to the flush. This version seems to keep him contented.

Source Naturals Niacinamide.

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.
