Injectable NAD+ has no approved label and no validated dosing schedule, so every figure here describes what has been studied or marketed rather than a recommendation. One pilot study infused roughly 750 mg IV over 6 hours purely to measure how NAD+ moves through the body, not to test a benefit.[1][2][3][4]
Reviewed for accuracy · Last reviewed July 8, 2026There is no validated dosing schedule for injected NAD+. The figures discussed in research and clinic settings are not standardized and have not been shown to produce clinical benefit:
Clinic-marketed NAD+ IV drips and subcutaneous protocols use ranges that vary widely and are not standardized or clinically validated. Infusions are commonly given slowly because faster rates are poorly tolerated. Because injected NAD+ is not an established therapy, treat any specific number as a description of practice, not a titration guideline.
This is separate from oral NAD+ precursors. Human trials of NMN (100 – 2000 mg/day) and NR show they raise blood NAD+ and are generally well tolerated, but those findings are about oral precursors and do not transfer to injected NAD+.
