Thanks for your feedback!

Great warm flush

Posted by iHerb Customer on March 11 2018 | Verified Purchase

This is my 2nd bottle of NIACIN 500mg. I take it in the morning before breakfast. The tingling and flush come fast. I come to like this sensation. Like blood rushing back into the arms after being blocked. The warmth also spread to the groin area. I could walk longer without feeling breathless. Some the mind also work more positively. Assertively. Will definitely continue . Now takin 2x500mg twice a day.

Thanks for your feedback!
