How does NAD+ work?
NAD+ is a helper molecule (coenzyme), not a peptide. This site's profile lists the full name Nicotinamide Adenine Dinucleotide, with a molecular weight of 663.4 daltons. It carries energy in the chemical reactions that power cells, and it is used up by enzymes called sirtuins and PARPs. Reviews cited on that page show NAD+ in the body's tissues drops with age. Whether giving NAD+ by IV or shot changes anything for a person is a different question. The one study in people on this site, a six-hour IV drip, found no rise in NAD+ or its breakdown products in the blood for the first two hours. It did not measure any symptom, energy, or disease result. This FAQ does not invent an anti-aging result from a coenzyme role. Full record at /compounds/nad-plus.
