Good product

Posted by Jodi-Hummingbird on Sep 03, 2013 | Verified Purchase

This is a good product, niacin is great stuff and Carlson Labs is a great brand but I am going to get the Bluebonnet 100 mg caps next time so that I'm taking in less fillers with my niacin. I wish Carlson's would do a niacin capsule!

Thanks for your feedback!

Junk or a bad bottle

Posted by Reviewer2562513 on May 20, 2012 | Verified Purchase

I have taken as many as nine of these at a time no flush what so ever and these are not flush free. My wife has tried the same amount many times too and nothing. When we take GNC 500 mg we feel a strong flush I am not sure if this was a bad bottle or what but IHerb if you monitor these reviews my wife feels a refund is in order for the amount of business we provide.

Thanks for your feedback!
