Dietary Supplement. 2800 mg Intensive. What is Vivaxl? Vivaxl is a rejuvenating, energy enhancing effervescent cocktail formulated for both men and women. Some people call it a happy cocktail. It took two years of research and planning to develop the complex formula for Vivaxl. We were determined to find the perfect blend of ingredients so that we could offer a quality product - pure, healthy and effective. This is a product that has benefits for every adult, any age. 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. Taking Vivaxl may help you to jump start your day; energize and sustain your workout; energize your mood; elevate your sense of well-being; combat the body blues; enhance sexual health; improve your quality of life.
