When I took my first Vivaxl, I noticed a warm red flush on my skin. What is that? Niacin is a B vitamin and a key ingredient in Vivaxl. One quality of Niacin is that it dilates blood vessels, creating a sensation of warmth often called a niacin flush. This harmless flush can also produce redness of the skin on the face and neck, as well as a tingling sensation for some. The reaction is usually mild, lasts 5-15 minutes, and will disappear with continued use of Vivaxl.
