Niacin B3

Niacin, or vitamin B3, is one of the essential B-complex water-soluble vitamins. This particular form is known as the "flushing" niacin. A "niacin flush" is when the skin flushes following taking high doses of niacin. It is harmless but may cause some discomfort. Flushing happens because niacin causes small blood vessels near the skin to widen. As a result, the skin gets warm and red. 

This product is only intended for those who are wanting this specific form of niacin.
