Reaction Niacin flush

Posted by iHerb Customer on Oct 01, 2017 | Verified Purchase

One word- RED - experienced a Niacin flush (red face, neck, shoulders, arms, legs, feet all over). I had to break my pills in half to lessen the effect but it didn't work, I still get flushes although they are not as severe as taking the entire pill. The flash lasted about an hour, so I don't recommend taking this if you are heading out of the door.

Thanks for your feedback!

Hot Flushes

Posted by iHerb Customer on Aug 08, 2017 | Verified Purchase

The hot flushes and itchiness were really severe. Some days no side effects and then suddenly you getbthe hot flushes again. Will not be taken again and will go back to the one from Dr Best.

Thanks for your feedback!

Very pleased.

Wrong product for me

Posted by iHerb Customer on May 19, 2017 | Verified Purchase

Sustained release Niacin apparently works well for a large number of people. I'm not one of them. I threw this product out and purchased a flushing version instead.

Thanks for your feedback!
