90 Day Supply: NAD+ (Nicotinamide Adenine Dinucleotide) is an essential coenzyme found in every living cell, acting as the master regulator of cellular energy and repair. It is crucial for redox reactions, enabling the mitochondria to convert the food we eat into ATP, the cell's primary energy currency. Beyond energy production, NAD+ serves as a vital cofactor for key longevity-associated enzymes like sirtuins and PARPs, which are responsible for DNA repair, regulating gene expression, maintaining chromosomal stability, and promoting resistance to cellular stress. As NAD+ levels naturally decline with age and environmental stress, replenishing them is a therapeutic target for combating age-related decline, enhancing metabolic function, improving cognitive clarity, and boosting overall cellular resilience and vitality.
