NAD+

Essential coenzyme for cellular energy, sirtuin activity, and DNA repair — central to longevity research.

Also known as: NAD · Nicotinamide Adenine Dinucleotide
SummaryMechanismDosingSafetyStudies
Research use only — not for human consumption.

What it is

NAD+ (nicotinamide adenine dinucleotide) is an essential coenzyme that supports cellular energy production and mitochondrial function. It powers redox metabolism, sirtuin and PARP signalling, and DNA repair processes. Tissue NAD+ levels decline with age — supplementation strategies aim to restore baseline and support energy, focus, and cellular resilience.

Mechanism of action

NAD+/NADH redox couple is central to glycolysis, the TCA cycle, and oxidative phosphorylation. NAD+ is a substrate for sirtuins (SIRT1–7), PARPs, and CD38, linking it to chromatin regulation, DNA damage response, and circadian / metabolic biology.

Half-life: Not established for administered NAD+: the one human IV study calculated no half-life and saw plasma NAD+ rise only after two hours (Grant 2019). The oral precursor nicotinamide riboside has a human half-life of ~2.7 hours (Airhart 2017).

Evidence summary

Strong preclinical case for NAD+ supplementation in aging, neurodegeneration, and metabolic disease. Human precursor trials show modest but real biomarker improvements; large outcome trials are still emerging.

NAD+ is an essential coenzyme that supports cellular energy production and mitochondrial function to promote vitality, recovery, and healthy aging.

Additional research protocol context

The printed guide above is Pantheon's dosing reference. These broader research examples are provided as context and may use different schedules.

  • Subcutaneous: 50–250 mg daily, titrate to flush tolerance
  • IV: 250–1,000 mg infused over 2–4 hours, weekly to monthly
  • Pair with NAD+ precursors (NMN, NR) and exercise

Side effects & safety

  • Flushing, chest pressure, nausea on rapid IV infusion — slow the rate
  • Mild fatigue or vivid dreams reported anecdotally
  • Methyl-donor depletion concern with chronic high doses — pair with B-vitamins
