NAD+ vs NMN
Side by side: what studies show, whether it is legal, doping and risks. No winner is shown on purpose.
| NAD+ | NMN | |
|---|---|---|
| Type | A compound in every cell, needed to make energy. Clinics offer it as drips and injections. No such medicine in the EU or US. | A substance the body turns into NAD+. Sold as a dietary supplement. |
| Stage | A mix, not a finished medicine | Still being studied |

| Longer life | E Not clear. A 2026 review found no study of the effects of NAD+ itself given by drip or injection. Studies test NMN and NR, which the body turns into NAD+, and their results on health are mixed or show no effect. | C Not clear. Studies are short and measure NAD in blood or fitness tests, not ageing. One found better muscle response to insulin and another found no change. |
