NAD+ 500MG

Nicotinamide adenine dinucleotide (NAD+) is a crucial coenzyme found in all living cells. It plays a vital role in various biological processes, primarily in metabolism and energy production. NAD+ is involved in redox reactions, where it alternates between its oxidized (NAD+) and reduced (NADH) forms, facilitating the transfer of electrons during cellular respiration and other metabolic pathways.

### Key Functions of NAD+:
1. **Energy Production**: NAD+ is essential in the process of glycolysis, the citric acid cycle (Krebs cycle), and oxidative phosphorylation, where it helps convert nutrients into adenosine triphosphate (ATP), the energy currency of the cell.
2. **Redox Reactions**: NAD+ acts as an electron carrier, accepting electrons during catabolic reactions and donating them during anabolic reactions.
3. **DNA Repair and Cell Signaling**: NAD+ is a substrate for enzymes like PARPs (poly ADP-ribose polymerases) and sirtuins, which are involved in DNA repair, gene expression, and cellular stress responses.
4. **Aging and Longevity**: NAD+ levels decline with age, and its depletion is associated with aging and age-related diseases. Boosting NAD+ levels has been explored as a potential strategy to promote healthy aging.
