NMN (Nicotinamide Mononucleotide)
Nicotinamide Mononucleotide / Beta-NMN
A nucleotide derived from ribose and nicotinamide that serves as a direct precursor to NAD+ (nicotinamide adenine dinucleotide). NAD+ is an essential coenzyme in >500 enzymatic reactions including sirtuins (SIRT1-7), PARPs, and CD38. NAD+ levels decline ~50% between ages 40–60, correlating with mitochondrial dysfunction and aging. NMN supplementation restores NAD+ levels in human studies, though long-term clinical benefits are still being established.

Evidence Overview
Strength of evidence across clinical, expert, and experimental lanes.
How NMN (Nicotinamide Mononucleotide) is dosed in practice
Usually taken by mouth. Typical range: 250–1000 mg/day. Half-life: ~2–3 hours (oral NMN; NAD+ elevation lasts longer). Each card gives the dose, frequency and duration from one evidence lane: Clinical (human trials), Expert (practitioner protocols) or Experimental (early or animal data). These ranges describe what has been studied or used; they are not a prescription.
Work out the units to draw with the reconstitution calculator, how long a vial lasts with the vial duration calculator, and how levels fall between doses with the half-life calculator.
Randomized trials giving 250–900 mg daily for 6–12 weeks raised blood NAD+. A 10-week trial in overweight postmenopausal women with prediabetes (2021) found better muscle insulin sensitivity; effects on physical performance elsewhere were small.
- Randomized trial in postmenopausal women with prediabetes (2021)
- Dose-ranging randomized trial (2023)
Popularized as a longevity supplement. Typically dosed 500–1000 mg daily, sublingual or oral, often combined with resveratrol and TMG (trimethylglycine). Taken in the morning. Look for enzymatically produced NMN for purity.
- Longevity medicine NAD+ restoration strategies
- NMN quality and bioavailability research
Massively popular in the longevity supplement market. Users report improved energy, better exercise recovery, and enhanced mental clarity — though placebo effects are hard to rule out. Sublingual formulations claim better bioavailability. Price has dropped significantly as manufacturing scaled. FDA attempted to ban NMN as a supplement (2022) but enforcement is ongoing.

How is NMN (Nicotinamide Mononucleotide) dosed?
NMN (Nicotinamide Mononucleotide) is usually taken by mouth. Typical range in DoseCraft's library: 250–1000 mg/day. Clinical (human trials): 250–900 mg daily; Once daily, typically morning; 6–12 weeks in randomized trials. Expert (practitioner protocols): 500–1000 mg daily; Once daily in the morning; Ongoing daily supplementation. Experimental (early or animal data): 250–1000 mg daily; Once daily, morning; Ongoing. These ranges describe what has been studied or used; they are not a prescription.
Is NMN (Nicotinamide Mononucleotide) FDA-approved?
NMN (Nicotinamide Mononucleotide) is sold as a dietary supplement, which the FDA does not approve for safety or effectiveness before sale.
What is the half-life of NMN (Nicotinamide Mononucleotide)?
DoseCraft's library lists a half-life of ~2–3 hours (oral NMN; NAD+ elevation lasts longer). Half-life sets how often a compound is dosed and how long it takes to clear: about five half-lives.
Who should not use NMN (Nicotinamide Mononucleotide)?
Listed contraindications: Active cancer (NAD+ fuels rapidly dividing cells — theoretical concern); Gout (purine metabolism pathway involvement); Pregnancy or breastfeeding (insufficient safety data).
