Supplement
NMN (Nicotinamide Mononucleotide)
NMN may help restore cellular energy by boosting NAD+ levels, which decline with age and potentially during menopause. Small studies in older adults show modest improvements in muscle strength and walking speed, though most participants were men. The cellular mechanism is scientifically sound, but we need studies specifically in menopausal women to know if it addresses the fatigue and metabolic changes we actually experience.

Overall: Mixed evidence
Randomised controlled trials
Small trials show modest benefits for muscle function and walking speed in older adults, but studies are limited and short-term.
Very limited observational data exists for NMN specifically.
No comprehensive meta-analyses of NMN exist due to the small number of human trials.
Menopause-specific trials
No studies have examined NMN specifically in perimenopausal or menopausal women.
What we do not know
No studies have tested NMN specifically in perimenopausal or menopausal women. We don't know the optimal dose for women in midlife, as most trials used 250mg in elderly men. Long-term safety beyond 12 weeks hasn't been established. We don't know if NMN affects hormone-related symptoms like hot flashes or sleep disruption. No research has compared NMN to other NAD+ precursors like NR in menopausal populations.
How it is used
Common dose range
250-500mg daily
Notes on dosing
Take in the morning. Store in refrigerator. NR (nicotinamide riboside) is a similar compound with slightly more human evidence.
Get it from food first
Food sources are better absorbed than most supplements and come with co-factors that support the same pathways. If you eat two or three of these consistently, you may not need a supplement at all.
Broccoli
0.25-1.12 mg per 100g
Highest vegetable source
Cabbage
0.0-0.90 mg per 100g
Variable depending on variety
Cucumber
0.56 mg per 100g
Consistent but modest source
Edamame
0.37-1.68 mg per 100g
Good plant protein plus NMN
Avocado
0.36-1.60 mg per 100g
Also provides healthy fats
Mediterranean-style eating
Rich in vegetables and olive oil that provide small amounts of NAD+ precursors while supporting overall cellular health
Adequate protein intake
Supports NAD+ synthesis pathways and provides building blocks for cellular repair
What depletes NMN (Nicotinamide Mononucleotide)
Alcohol consumption significantly depletes NAD+ levels. High sugar intake may impair NAD+ metabolism. Chronic stress and poor sleep disrupt cellular energy pathways that depend on adequate NAD+.
Interactions and cautions
No significant interactions noted at recommended doses.
Rose bottom line
"The science behind NAD+ and cellular energy is solid, but the evidence for NMN in our specific situation is thin. If you're drawn to the cellular energy angle, focusing first on proven energy supporters like adequate protein, strength training, and quality sleep will give you more reliable results while research catches up."
