NMN
NMN is a precursor to NAD+, supporting energy metabolism, cellular repair, and healthy aging.
NMN (Nicotinamide Mononucleotide) is a precursor to NAD+, a molecule essential for energy production and cellular repair.
It supports healthy aging, mitochondrial function, and metabolic balance by boosting NAD+ levels in the body.
NMN supplements are considered safe and are increasingly popular in longevity and anti-aging regimens.
Other names & forms of NMN supplement : NMN, nicotinamide mononucleotide, beta-nicotinamide mononucleotide, longevity supplement, NAD+ precursor
Possible Benefits
NMN (Nicotinamide Mononucleotide) serves as a direct precursor to NAD⁺, boosting mitochondrial function and enhancing cellular energy production.
- Helps support Energy & Metabolism by increasing NAD⁺ levels, which are essential for ATP synthesis.
- May contribute to Anti-Aging through activation of sirtuin enzymes that promote DNA repair and longevity pathways.
- Supports Heart Health by improving cardiomyocyte bioenergetics and resilience against age-related decline.
- Often used to bolster Cognitive Health by safeguarding neuronal mitochondria and reducing neurodegenerative risk.
Side Effects
NMN (Nicotinamide Mononucleotide) boosts cellular NAD+ levels for energy, but during the adaptation phase you may notice mild effects. Watch for:
- Possible mild flushing or warmth sensation
- Occasional headache or lightheadedness
- Temporary mild fatigue as metabolism adjusts
- Rare gastrointestinal discomfort, nausea or cramps
- Very mild changes in sleep quality
Interactions
Possible interactions include:
- Antioxidant therapies: NMN’s NAD+ support complements CoQ10 and resveratrol; monitor overall antioxidant load.
Precautions
Before supplementing with NMN, confirm none of the following apply to you. If they do, consult your healthcare provider:
- Individuals with liver or kidney impairment: Monitor organ function if used long term
- People on chemotherapy or radiation: May interfere with therapies; discuss with oncologist
- Those with hypotension: May cause slight blood pressure changes; monitor regularly
- Pregnant or breastfeeding women: Safety not established; avoid high-dose use
- Patients scheduled for surgery: Discontinue at least one week prior, possible anesthesia interactions
Studies
These studies provide scientific insights into NMN benefits:
A 2023 randomized, double-blind trial in 120 postmenopausal women found 250 mg/day nicotinamide mononucleotide for 12 weeks improved insulin sensitivity by 12% versus placebo and increased NAD⁺ levels by 40%.
A 2022 crossover study in 30 healthy older adults reported 300 mg/day NMN for 6 weeks enhanced aerobic capacity versus control .
