Despite the heat that gets generated in the different parts of the body from this supplement the effectiveness of its use is noticeable within 7 days.

The Niacin Flush

I take this before I go to the sauna. I get a Niacin flush and my ears turn red and they start burning. It's an excellent product.

I made sure to check that this is not prolonged release. When I got it I saw prolonged release. iHerb didnt have the picture updated! This one star is more to iHerb than to 21st century! All otehr, I am happy with iHerb, except this one time!
