CellGuard-NR™ is uniquely formulated to support the body’s natural cellular repair process, antioxidative status, and healthy aging.* This formula contains clinically relevant amounts of Niagen®, a form of nicotinamide riboside chloride (NR), resveratrol as Veri-te™, and pterostilbene. NR is a variation of vitamin B3 (niacin) and is a building block to nicotinamide adenine dinucleotide (NAD+). NAD+ is found in every living cell and is essential to many important cellular processes including energy production. NAD+ plays a role in more than 500 reactions in the body, including gene expression, stress response, and DNA repair. Resveratrol is a bioactive plant compound found in grape skin, berries (such as blueberries and raspberries), and peanuts. It is known for its role in supporting a healthy response to oxidative stress and inflammation.
