NAD+
Longevity coenzyme Limited evidence 3 cited studies 95 live vendors
NAD+ (nicotinamide adenine dinucleotide) is a naturally occurring coenzyme found in all living cells, where it participates in redox reactions and serves as a substrate for enzymes involved in cellular energy metabolism and signaling. In research settings it is studied for its roles in mitochondrial function, DNA repair pathways, and cellular aging in laboratory models. This index tracks research-use-only vendor pricing for NAD+ so researchers can compare cost across suppliers.
Evidence brief
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme central to energy metabolism and a cosubstrate for enzymes such as the sirtuins; its tissue levels decline with age in the models reviewed.

These figures are what pepmg still publishes about price: the floor, the middle, the spread and how many sources we track, computed from listings we captured first-party and refreshed on the same schedule as always. We no longer publish the individual listings or the sellers behind them.
Computed from 142 in-stock listings across 95 sources we captured first-party, with bulk vials, blends and statistical outliers excluded so the figures compare like with like. The spread is the highest tracked price divided by the lowest — how much the same milligram varies depending on where you look. The chart is the daily minimum; days we did not capture are left out rather than filled in.

▸ Why compare $/mg for NAD+?
Per-mg NAD+ prices vary because vendors differ in source material, stated purity, lot testing, and vial sizes, and because NAD+ is often sold in a wide range of quantities that change the effective unit cost. Comparing normalized $/mg across suppliers helps a researcher separate genuine value from packaging differences and identify outliers in either direction.
▸ Reading the COA
For NAD+, confirm identity on the COA by mass spectrometry against the expected molecular weight (~663.4 Da for the free acid) and check HPLC purity, ideally 98%+ for research-grade material. Because NAD+ readily degrades, watch for elevated levels of common breakdown products such as nicotinamide and ADP-ribose, which indicate hydrolysis; a reputable COA reports these as named impurities rather than a single lumped figure.
