CellGuard-NR™ is a premium formula designed to support antioxidants and health. It features clinically significant amounts of Niagen® (nicotinamide riboside chloride), Verite™ resveratrol, and pterostilbene. As a B vitamin, NR serves as a direct precursor for the formation of NAD+ (nicotinamide adenine dinucleotide), a crucial molecule for energy metabolism. Together, these nutrients work synergistically to promote a balanced cell cycle and a healthy response to oxidative stress.
