NAD+ is a helper molecule found in every cell. Cells use it to make energy and repair DNA. Levels drop as we age.
Animal studies link low NAD+ to ageing. In people, injected NAD+ has only small pilot studies. It can sting and cause flushing if injected fast.

| Used for | Dose | How often |
|---|---|---|
| Starting (weeks 1 to 4) | 50 mg | Once a week |
| Step up | 75 mg | 1 to 3 times a week |
| Maintenance | 100 mg | 2 to 3 times a week |
Under the skin or into the muscle only on this page; IV infusions belong in a clinic. Public references give 50 to 100 mg per injection, 1 to 3 times a week, rising slowly, with about 300 mg a week as an upper limit. Inject slowly: it can sting and cause flushing. Older profiles listing 250 to 1000 mg doses were IV or clinic amounts and were not carried.

NAD+ is a natural coenzyme in every cell, and its levels fall with age in animals and people. Injected NAD+ has only small pilot human studies; most support for using it comes from animal research and from studies of oral precursors (NMN, NR).
