David Sinclair's Supplements List (With Dosages) 2025
David Sinclair continues to refine his supplement routine using current clinical data and biomarker feedback. His 2025 regimen focuses on compounds shown to impact aging at molecular and cellular levels.
Nicotinamide Mononucleotide (NMN)
Sinclair consistently takes NMN daily to support NAD+ metabolism. His typical dosage is 1,000 mg each morning, mixed with yogurt to aid absorption. You’ll see NMN in several human trials for boosting cellular energy and sirtuin activation, including studies published in Cell Reports and the Journal of Clinical Investigation.
Resveratrol
Sinclair likely consumes 1,000 mg of resveratrol daily, taken alongside NMN and fat-containing foods to improve absorption. He credits resveratrol for improving mitochondrial function and sirtuin activation. He cites studies from the Science and Nature journals as supporting evidence for its anti-aging roles.
Metformin
Sinclair has publicly discussed taking 500 mg of metformin per day, usually in the evening. He suggests metformin may optimize glucose metabolism and reduce oxidative stress, but notes that he sometimes pauses use when exercising intensely, referencing literature that highlights interactions between metformin and muscle adaptation.
Spermidine
Sinclair adds spermidine to his protocol at a daily dose of 1-2 mg. Citing preclinical research in Nature Cell Biology, he links spermidine with autophagy support and healthy aging outcomes. You can find spermidine in wheat germ or through formulated supplements.
Vitamin D3 And K2
Sinclair uses vitamin D3 at a dose of 2,000 IU and couples it with 180 mcg of vitamin K2 to optimize absorption and calcium metabolism. His regimen references clinical data associating these vitamins with decreased inflammation and improved cardiovascular markers.
Quercetin And Fisetin
Sinclair includes quercetin and fisetin as part of his senolytic strategy. He typically takes 500 mg quercetin and 500 mg fisetin intermittently, aligning with research from the Aging Cell journal and pilot clinical trials showing potential for clearing senescent cells.
Other Notable Supplements
Sinclair occasionally adds omega-3 (standard dose: 1,000 mg/day EPA and DHA), Coenzyme Q10 (100 mg/day), and alpha-lipoic acid (600 mg/day) to his protocol for mitochondrial and cardiovascular support. He also notes occasional aspirin (83 mg/day) for heart health in consultation with a healthcare provider, and takes a multivitamin as nutritional insurance.

Daily Supplement Routine And Timing
David Sinclair’s daily supplement routine relies on precise timing and consistent intake. He typically consumes most supplements after waking, pairing compounds like NMN, resveratrol, and metformin with his morning routine to maximize bioavailability and support NAD+ pathways during the cellular repair window.
Take NMN (1,000 mg) and resveratrol (1,000 mg) together in the morning with a source of fat, such as yogurt, to enhance resveratrol absorption as suggested in published protocols (Cell, 2013). Swallow vitamin D3 (2,000 IU) with K2 (180 mcg) alongside breakfast for best absorption, since both vitamins are fat-soluble. Take spermidine (1–2 mg), quercetin (500 mg), and fisetin (500 mg) after your first meal or as directed in clinical trials, aligning with your body’s metabolic rhythm. Take metformin (500 mg) in the morning, unless prescribed otherwise, as Sinclair follows a practice of avoiding it on intense workout days to prevent blunting exercise adaptations.
Supplement Timing Table
| Supplement | Dosage (mg/IU/mcg) | Timing | Method/Notes |
|---|---|---|---|
| NMN | 1,000 mg | Morning, with food | Combine with fat for absorption |
| Resveratrol | 1,000 mg | Morning, with NMN | Pair with fat and NMN |
| Metformin | 500 mg | Morning, skip on hard workout days | Prescription-based |
| Spermidine | 1–2 mg | Morning or with food | Follow clinical dosing patterns |
| Vitamin D3 + K2 | 2,000 IU + 180 mcg | With breakfast | Fat-soluble vitamins |
| Quercetin | 500 mg | With first meal | Supports senolytic action |
| Fisetin | 500 mg | With first meal | Combine with other senolytics |
| Omega-3s, CoQ10, ALA, Aspirin | See label | As needed, with meals | Occasional use, meal-dependent |
You align supplement timing with your meal schedule and exercise habits to optimize efficacy and minimize side effects. Tracking intake time helps maintain consistency and supports more reliable health outcomes when assessing biomarkers.

Potential Benefits And Risks Of Following The List
Adopting David Sinclair's 2025 supplement protocol can influence your longevity strategy by leveraging compounds studied for cellular health and lifespan support.
Potential Benefits
- Supporting NAD+ metabolism
NMN at 1,000 mg daily may raise NAD+ levels, which clinical studies indicate can boost cellular energy and DNA repair (Yoshino et al., 2011).
- Enhancing mitochondrial function
Resveratrol at 1,000 mg interacts with sirtuin pathways and mitochondrial biogenesis based on data from animal and early-phase human studies (Baur et al., 2006).
- Improving metabolic health
Metformin at 500 mg is associated with better glucose regulation, as shown in multiple randomized controlled trials involving diabetic and prediabetic populations (Knowler et al., 2002).
- Promoting autophagy
Spermidine at 1-2 mg daily has links to improved autophagic clearance per clinical studies published in Nature Medicine (Eisenberg et al., 2016).
- Supporting cardiovascular health
Vitamin D3 at 2,000 IU and vitamin K2 at 180 mcg function together to optimize arterial flexibility and bone metabolism according to 2022 meta-analyses (Kanellakis et al., 2022).
- Advancing senolytic strategies
Fisetin and quercetin at 500 mg each demonstrate the ability to clear senescent cells in preclinical models (Yousefzadeh et al., 2018). These compounds are being evaluated in pilot human trials.
Potential Risks
- Limited long-term safety data
High-dose NMN, resveratrol, and spermidine have sparse human safety profiles beyond 12-24 months.
- Drug-supplement interactions
Metformin, aspirin, and vitamin K2 can interact with prescription medications, affecting anticoagulation, glycemic control, and liver metabolism.
- Gastrointestinal upset
NMN, resveratrol, and polyphenols may cause loose stools, nausea, or bloating, especially when first introduced or at high doses.
- Unknowns in dose extrapolation
Most longevity findings in animal models involve higher proportional doses and don’t always translate to humans. Efficacy and risk thresholds for long-term use remain under review.
- Overlapping or excessive intake
Combining multiple supplements that modulate mitochondrial or autophagy pathways increases the potential for adverse effects or unintended biological impacts.

Considerations Before Starting Any Supplement
Evaluating potential supplement interactions protects your health, especially if you're combining prescribed medications with ingredients in Sinclair's stack like metformin or aspirin. Research from the National Institutes of Health (NIH) highlights risks when layering supplements such as vitamin D3 and quercetin with pharmaceutical drugs or other micronutrients.
Discussing your supplement regimen with a qualified healthcare provider supports personalization and reduces the chance of adverse events, particularly in populations with chronic conditions or advanced age. Surveys indicate physicians can recommend lab monitoring—such as assessing glucose levels, liver enzymes, or epigenetic markers—before introducing NMN, resveratrol, or metformin.
Reviewing safety profiles and evidence strength for each supplement in Sinclair's 2025 protocol ensures an informed approach. Peer-reviewed journals note that long-term data for ingredients like spermidine and high-dose fisetin remain limited, so adopting new supplements relies on real-time clinical and biomarker feedback.
Monitoring for side effects—such as mild GI discomfort from NMN or vitamin K2—alerts you to unwanted outcomes. According to Mayo Clinic, tracking any new symptoms guides rapid adjustments to your daily routine.
