Nicotinamide adenine dinucleotide (NAD+) is a coenzyme essential to energy production, mitochondrial health, and the activation of sirtuins—longevity regulators that influence how gracefully the body ages. NAD+ also plays a critical role in sleep quality, stress resilience, and metabolic function. Yet NAD+ levels can decline by as much as 50% by the time adults reach their 40s, accelerating fatigue, cellular wear, and age-related changes. NAD+ Longevity features Bioenergy RiaGev-WS (750 mg)—a proprietary blend of Bioenergy Ribose and Nicotinamide Ascorbate—that raises NAD+ levels more efficiently than conventional precursors. Unlike other NAD+ supplements that must first be broken down into components like D-ribose and nicotinamide before the body can use them, RiaGev-WS is readily converted and goes straight to work. The formula is further fortified with Vitamin C (218 mg) and Niacin (67.5 mg) to amplify cellular support. This advanced formula simultaneously supports NAD+, ATP (cellular fuel), and glutathione (the body's master antioxidant), creating a powerful energy-boosting trio that promotes vitality, healthy aging, balanced cortisol, and optimal metabolic function.FDA Disclaimer:These statements have not been evaluated by the Food and Drug Administration.
