Simply enerGmakes my face feel warm and tingly – what is going on?
What you are feeling is known as the “niacin flush.” The niacin flush is just a reaction to the niacin (Vitamin B3). When some people receive niacin the blood vessels in the face dilate and their face has a reddish look for 5 to 10 minutes. It’s harmless and just a sign that the body needs more B3 then it has been receiving. Some people like it – it is a natural invigorating and euphoric feeling.
