Nice to take B6 without going red in the process.

It does not say so clearly on the bottle- but this is time released niacin which could cause LIVER DAMAGE!!!! I prefer to take the regular fast-acting niacin which does not have those side effects!!!!

A basic niacin

Posted by Reviewer1612446 on Apr 24, 2015

This is just a basic niacin. The tablets are reasonably small, which is nice.

Take Niacin to raise HDL and lower triclycerides !!

Posted by Sickness-ELIMINATOR on Dec 21, 2013

I have high triglycerides and low HDL. 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 (or taste good).

I'm switching to another brand, because this sometimes gives me a flush that itches and looks like hives (for about half an hour).
