CellGuard-NR™ is a specialised cellular health formula that blends nicotinamide riboside chloride (NR), resveratrol, and pterostilbene to support the body’s natural repair processes and antioxidant defences. It features Niagen®, a clinically studied form of NR, which acts as a precursor to NAD+—a key molecule involved in over 500 essential cellular functions, including DNA repair, gene expression, and stress response.
This formula also includes Veri-te™ resveratrol, a plant-derived compound found in grape skins and berries, which helps support a healthy response to oxidative stress and contributes to normal inflammation balance. Pterostilbene, a structurally similar but more bioavailable compound, complements resveratrol by further supporting antioxidant status and cellular function.
Together, these ingredients promote a healthy cell cycle, encourage cellular regeneration, and help the body maintain vitality as it ages. CellGuard-NR™ helps you support long-term cellular health, resilience, and graceful ageing from within.
