I didnt order with prolonged release and got a prolonged release one!

Posted by 5404133596940222250 on May 09, 2015 | Verified Purchase

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!

The Niacin Flush

Posted by Harpocrates on Oct 11, 2012 | Verified Purchase

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.

The heat is on.

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.

Great product

I am drinking it since I have seen the studies it can help with some lighter "mood downs". I am repurchasing regularly.
