NMN
A direct precursor to the vital anti-aging coenzyme NAD+.
Also known as: Nicotinamide Mononucleotide • β-NMN
Overview
Nicotinamide Mononucleotide (NMN) is a nucleotide that serves as a direct precursor to Nicotinamide Adenine Dinucleotide (NAD+), a critical coenzyme for cellular energy, metabolism, and DNA repair. NAD+ levels decline with age, and NMN supplementation aims to counteract this decline, supporting longevity and healthy aging.
Key Benefits
Enhanced Cellular Energy
By increasing NAD+ levels, NMN supports mitochondrial function, leading to improved energy production and reduced fatigue.
DNA Repair and Genomic Stability
NAD+ is essential for PARP enzymes, which are critical for repairing damaged DNA and maintaining genomic integrity.
Sirtuin Activation
Sirtuins, a class of proteins linked to longevity (often called 'longevity genes'), require NAD+ to function. NMN helps activate these pathways.
Dosage & How to Take
250-1000 mg per day, often taken in a single morning dose.
| Purpose | Dose | Notes |
|---|---|---|
| General Anti-Aging Support | 250-500 mg/day | A common starting dose for healthy individuals. |
| More Intensive Support | 500-1000 mg/day | Higher doses may be used for specific health goals, often guided by a healthcare provider. |
Best Time to Take
Best taken in the morning on an empty stomach to maximize absorption and align with the body's natural circadian rhythm.
With or Without Food
Can be taken with or without food, but absorption may be slightly better on an empty stomach.
Forms & Bioavailability
| Form | Absorption | Best For | Notes |
|---|---|---|---|
| Standard Powder/Capsules | Moderate. Some degradation can occur in the stomach. | Cost-effective entry point. | The most common and widely available form. |
| Sublingual Powder/Liquid | High. Absorbed directly into the bloodstream under the tongue. | Faster and more efficient NAD+ boosting. | Bypasses first-pass metabolism in the liver. |
| Liposomal NMN | Very High. Encapsulated in lipids to protect it from degradation and enhance cellular uptake. | Maximizing absorption and effectiveness. | Often considered the premium form. |
Side Effects & Safety
Common
- Generally well-tolerated. Some users report mild flushing, nausea, or stomach discomfort at higher doses.
Rare
- Headaches, dizziness. Long-term side effects are not well-documented in humans.
Contraindications
- Pregnant or breastfeeding women should avoid use due to lack of safety data. Consult a doctor if you have a history of cancer.

Scientific Research
The first human clinical trial of NMN
A single 500mg dose of NMN was found to be safe and effectively metabolized in healthy men without causing significant adverse effects.
NMN supplementation enhances aerobic capacity in amateur runners
NMN supplementation improved ventilatory threshold and O2 pulse in amateur runners, suggesting enhanced oxygen utilization.
