NAD+ (Nicotinamide Adenine Dinucleotide) is a naturally occurring molecule essential for cellular health. It functions as a coenzyme in redox reactions, transferring electrons to support key metabolic processes. NAD+ also acts as a substrate for enzymes such as sirtuins and PARPs, which play vital roles in DNA repair, cellular signaling, and maintaining overall cell function. Why is NAD+ Important? Energy Production: NAD+ is crucial for producing ATP—the primary energy source for cells—through the process of cellular respiration. DNA Repair: It serves as a key substrate for PARP enzymes, which are responsible for detecting and repairing damaged DNA. Cellular Signaling: NAD+ plays a role in important signaling pathways, including those regulating calcium movement and protein modification. Healthy Aging: NAD+ levels naturally decline with age. Restoring or boosting NAD+ has been linked to potential benefits in slowing age-related decline and supporting longevity.
