TRU NIAGEN® is a revolutionary cellular health nutrient manufactured by ChromaDex, a company rooted in science. Working with some of the world’s leading scientists, ChromaDex is committed to uncovering the full potential of Tru Niagen® and learning more about the profound impacts it can have on cellular health, repair, and resilience. Tru Niagen® is a unique form of vitamin B3 known as nicotinamide riboside (Niagen®). Niagen® is an NAD+ precursor and functions as a building block for your body to build NAD+. That’s important as NAD+ is a coenzyme that is vital to cellular health--but NAD+ levels decline with age and other physiological stressors such as poor diet, drinking, lack of sleep, or too little or too much exercise. Tru Niagen® is scientifically proven to help your body increase NAD+. And Niagen® is the first and only patented and FDA safety reviewed form of nicotinamide riboside.
