NAD+
NAD+ — Description NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme found in every cell of the body. It is essential for life because it fuels many of the body’s most important biological processes, especially those related to energy production, cellular repair, and healthy aging. What Is NAD+? NAD+ is a molecule that exists in two forms: NAD+ (oxidized form) NADH (reduced form) Together, they play a central role in converting nutrients into usable energy within the mitochondria — the cell’s “power plants.” Key Functions of NAD+ Energy Production (ATP generation) NAD+ is required for breaking down carbohydrates, fats, and proteins into energy. DNA Repair Activates sirtuins (SIRT1–SIRT7), enzymes that repair DNA damage and support cellular resilience. Healthy Aging NAD+ levels naturally decline with age; boosting levels may support cellular longevity. Metabolism Regulation Helps maintain proper metabolic function, including blood sugar and fat metabolism. Cellular Stress Resis
