David Sinclair Supplements List: Complete 2025 Guide
Discover David Sinclair's complete 2025 supplement regimen including NMN, resveratrol, metformin, and more. Learn the Harvard professor's science-backed approach to longevity with detailed dosages, timing, and rationale for each supplement.
Introduction to David Sinclair's Approach to Supplements
David Sinclair, PhD, is a Harvard professor, co-director of the Paul F. Glenn Center for Biology of Aging Research, and author of Lifespan: Why We Age—and Why We Don't Have To. Known for his work on sirtuins, NAD+ boosters, and aging reversal, Sinclair shares his protocols via podcasts, books, and social media. His supplement regimen focuses on boosting NAD+ levels, activating longevity genes, and mimicking caloric restriction, personalized through biomarkers and ongoing research. In 2025, his stack includes updates like adding taurine and switching from quercetin to fisetin for better senolytic effects, while emphasizing evidence from human trials.
This guide outlines David Sinclair's 2025 supplements list, based on his disclosures and analyses, with dosages, timing, and rationales. He cycles some items and discloses potential conflicts (e.g., co-founder of companies like InsideTracker).

Why Does David Sinclair Take Supplements?
Sinclair's philosophy targets the "information theory of aging," using supplements to restore NAD+, activate sirtuins, promote autophagy, and clear senescent cells. Guided by RCTs and animal studies, he focuses on:
- NAD+ Restoration: Declines with age; boosters like NMN combat this.
- Longevity Pathways: Activates sirtuins (resveratrol) and AMPK (metformin).
- Evidence-Based: Prioritizes human data, e.g., NMN's effects on blood pressure and lipids.
- Risk-Benefit: Monitors via blood tests; skips metformin on workout days to avoid muscle interference.
In his book and posts, he evaluates via mechanisms like sirtuin activation and mTOR inhibition.
David Sinclair's Daily Supplements List (2025 Update)
His stack is approximately 10–15 items, with dosages personalized. Adjust via testing.
| Supplement | Dosage | Timing | Brand/Example | Key Benefits |
|---|---|---|---|---|
| NMN (Nicotinamide Mononucleotide) | 1 g | Morning (with yogurt) | Not specified (high-purity) | Boosts NAD+ for energy, DNA repair; human trials show improved weight, lipids, blood pressure |
| Resveratrol | 1 g | Morning (with yogurt/olive oil) | Not specified | Activates sirtuins for longevity; anti-inflammatory, heart health |
| Metformin (Rx) | 800–1,000 mg | Evening (skips on workout days) | Prescription | Mimics fasting via AMPK; insulin sensitivity, potential lifespan extension |
| Spermidine | 1–2 mg | Morning | Not specified | Autophagy promotion; cellular renewal, heart/brain health |
| Fisetin | 500 mg | Morning (with yogurt) | Not specified | Senolytic; clears zombie cells, reduces inflammation |
| Taurine | 2 g | Morning | Not specified | Mitochondrial support, oxidative stress reduction; lifespan extension in animals |
| Omega-3 Fish Oil (EPA/DHA) | 1–3 g | Not specified | Not specified | Anti-inflammatory; heart, brain health |

| Vitamin D3 | 4,000–5,000 IU | Not specified (with meals) | Not specified | Immunity, bone health; reduces mortality risk |
| Vitamin K2 (MK-7) | 180–360 mcg | Not specified (with D3) | Not specified | Calcium metabolism; heart, bone protection |
| TMG (Trimethylglycine/Betaine) | 500–1,000 mg | Morning (with NMN) | Not specified | Methyl donor; homocysteine control, energy support |
| Low-Dose Aspirin | 83 mg | Daily | Not specified | Anti-clotting; inflammation/cancer reduction |
| Rapamycin (Rx) | Not specified (weekly/monthly) | Intermittent | Prescription | mTOR inhibition; lifespan extension in models |
| CoQ10 | 100–300 mg | Not specified (with fat) | Not specified | Mitochondrial energy; antioxidant protection |
Detailed Breakdown of Each Supplement
NAD+ Boosters
NMN and Resveratrol form the core, synergizing to elevate NAD+ and activate sirtuins. NMN backed by Harvard trials for metabolic benefits; resveratrol for DNA protection.
Metabolic Regulators
Metformin mimics fasting; TMG prevents methyl depletion from NAD+ boosters. Taurine (new addition) for mitochondrial health.
Cellular Cleaners
Spermidine for autophagy; Fisetin as senolytic (replaced quercetin for efficacy).
Antioxidants & Essentials
ALA, CoQ10, Omega-3 for mitochondria/inflammation; Vitamins D3/K2 for bones/heart; Aspirin for clots; Rapamycin intermittently for mTOR.
Supplements David Sinclair No Longer Takes
- Quercetin: Switched to fisetin in 2025 for superior senolytic activity in studies.
- Statin: Takes if cholesterol is high, but not core daily.
How to Optimize Your Own Supplement Routine Like Sinclair
- Biomarker Testing: NAD+, lipids, inflammation via InsideTracker.
- Quality Sources: Third-party tested for purity.
- Gradual Start: One at a time; monitor side effects.
- Lifestyle Integration: Pair with IF, exercise, low-sugar diet.
- Cycle/Adjust: Skip metformin pre-workout; consult for Rx.
