🍷 Resveratrol and NR/NMN: From Sinclair's Mice to Human Trials
What research on NAD+ and resveratrol actually showed
Resveratrol and NAD+ precursors (NR, NMN) attracted attention after David Sinclair's mouse experiments. Let's look at what human research showed.
Sinclair's story
In 2006, David Sinclair's lab (Harvard) showed that resveratrol activates sirtuins and improves the health of mice on a high-calorie diet. This launched the longevity research boom.
- 2006 — Sinclair's study.
- Resveratrol activates sirtuins.
- Mice lived longer and healthier.
- Start of the NAD+ booster era.
NAD+ mechanism
NAD+ is a key coenzyme of cellular metabolism and energy. Its level declines with age. NR (nicotinamide riboside) and NMN (nicotinamide mononucleotide) are precursors that raise NAD+.
- NAD+ — energy coenzyme.
- Declines with age.
- NR and NMN are precursors.
- Raise NAD+ levels.
Sirtuins
Sirtuins (SIRT1-7) are proteins linked to longevity, DNA repair and metabolism. They depend on NAD+. Resveratrol and NAD+ boosters activate them.
- SIRT1 — key sirtuin.
- DNA repair.
- Metabolic regulation.
- Depend on NAD+.
Resveratrol
Resveratrol is a polyphenol from red grapes. It activates sirtuins and has antioxidant properties. Research doses are high and not achievable from wine.
- Polyphenol from grapes.
- Activates SIRT1.
- Antioxidant.
- Research doses are high.
NR and NMN
NR (nicotinamide riboside) and NMN (nicotinamide mononucleotide) are NAD+ boosters. They replenish NAD+, which declines with age.
- NR — NAD+ precursor.
- NMN — NAD+ precursor.
- Replenish NAD+ levels.
- Support cellular energy.
Human trials
Human studies confirmed that NR and NMN are safe and raise blood NAD+. However, significant effects on health and longevity are not yet proven.
- NR and NMN are safe.
- Raise blood NAD+.
- Health effect is debatable.
- Long-term data needed.
Dosages
| Substance | Research dose |
|---|---|
| NR | 250–1000 mg/day |
| NMN | 250–1000 mg/day |
| Resveratrol | 150–1000 mg/day |
Practice
- Do not expect miracles — human effects are debatable.
- Start with low doses of NR or NMN.
- Resveratrol — in verified forms.
- Do not replace a healthy lifestyle with supplements.
- Consult a doctor.
Who is Sinclair?

What are NMN and NR?
NAD+ precursors that raise its level in cells.
How does resveratrol affect aging?
It activates sirtuins (SIRT1), linked to cell protection.
What is NAD+?
A key coenzyme of cellular metabolism and energy, declining with age.
Does it work in humans?
NR and NMN raise NAD+, but significant health effects are not yet proven.
What dosages?
NR/NMN 250–1000 mg/day, resveratrol 150–1000 mg/day.
Are NMN/NR safe?
In human studies they are safe, but long-term data are limited.
Should I take them?
As prescribed by a specialist; does not replace a healthy lifestyle.
What are sirtuins?
Proteins linked to longevity, DNA repair and metabolism.
When is a doctor needed?
With diseases, medications and before high doses.
