❓ Quick Answers
What is the David Sinclair Protocol?
The David Sinclair Protocol is a longevity supplement regimen designed to support cellular health and healthy aging. It includes NMN (nicotinamide mononucleotide), resveratrol, berberine (previously metformin), spermidine, fisetin, vitamin D3 with K2, omega-3 fatty acids, and intermittent rapamycin under medical supervision. The protocol targets NAD+ boosting, sirtuin activation, and autophagy induction.
How does the David Sinclair Protocol work?
The protocol works by targeting multiple aging pathways simultaneously. NMN boosts NAD+ levels to fuel cellular repair[Evidence: A][12]. Resveratrol activates SIRT1 longevity genes[Evidence: A][1]. Berberine supports metabolic health through AMPK activation. Together, these compounds may help cells function more youthfully.
What supplements does David Sinclair take daily?
As of 2026, Sinclair takes NMN (1g), resveratrol (1g with yogurt), berberine (800mg, replacing metformin in 2025), spermidine (1mg), fisetin (500mg intermittently), vitamin D3 (4,000-5,000 IU) with K2, omega-3s, alpha-lipoic acid, and low-dose aspirin. He also takes rapamycin intermittently under physician supervision.
Is the David Sinclair Protocol safe?
Studies suggest NMN supplementation is safe and well-tolerated in healthy middle-aged adults[Evidence: B][13]. However, prescription components like rapamycin carry significant risks including immunosuppression and require medical oversight. Always consult your doctor before starting any longevity supplement regimen, especially if you take medications.
How much does the David Sinclair Protocol cost?
The full protocol costs approximately $150-$400 per month depending on brand quality and sources. NMN is the most expensive component at $60-$120 per month for 1g daily. Budget options using foundational supplements (vitamin D3, omega-3s, berberine) can cost $30-$50 per month as a starting point.
Does David Sinclair still take metformin?
No. In June 2025, Sinclair switched from metformin to berberine, citing better digestive tolerance. Research shows berberine's effects on blood sugar control are comparable to metformin 500mg three times daily[Evidence: A][10]. He also discontinued TMG and taurine from his previous protocol.
What are the benefits of the David Sinclair Protocol?
Research suggests potential benefits include increased NAD+ levels[Evidence: A][12], improved walking speed and sleep quality with NMN[Evidence: B][13], cardiovascular protection from omega-3s[Evidence: A][5], and metabolic improvements from berberine[Evidence: A][10]. Human lifespan extension remains unproven.

🔬 How Does the David Sinclair Protocol Work?
The David Sinclair Protocol targets aging at the cellular level through four interconnected pathways. Understanding these mechanisms helps explain why Sinclair combines specific supplements rather than taking just one.
NAD+ Boosting: Refueling Your Cells
Think of NAD+ as the fuel that powers your cellular repair crews. As you age, NAD+ levels naturally decline, leaving your cells running on empty. NMN (nicotinamide mononucleotide) is a direct precursor to NAD+, essentially providing the raw materials your body needs to make more of this critical molecule. Studies show NMN supplementation significantly elevates blood NAD+ levels[Evidence: A][12], though evidence for downstream metabolic benefits remains limited.
Sirtuin Activation: Waking Up Your Longevity Genes
Sirtuins are proteins that act like cellular supervisors, overseeing DNA repair, inflammation control, and metabolic regulation. Resveratrol works like a master key that activates these supervisors, particularly SIRT1. Research shows resveratrol supplementation produces dose-dependent effects on SIRT1 activation, with stronger effects when taken for less than 12 weeks[Evidence: A][1]. In healthy adults, both resveratrol and caloric restriction increased circulating SIRT1 levels[Evidence: B][2][3]. However, results vary across studies. 7 showed significant SIRT1 increase, 2 showed decrease, and 3 showed no change[Evidence: D][11].
Metabolic Optimization: The Metformin-Berberine Switch
Both metformin and berberine activate AMPK, your cellular energy sensor that triggers beneficial stress responses similar to exercise and fasting. Early research suggests metformin may support healthspan through AMPK activation, with strongest evidence for preventing metabolic disease[Evidence: D][4]. Sinclair switched to berberine in 2025 because research shows comparable efficacy to metformin with fewer digestive side effects. Berberine significantly reduces triglycerides, LDL cholesterol, BMI, and blood sugar[Evidence: A][10].
Autophagy Induction: Cellular Recycling
Autophagy is your body's cellular recycling program, clearing out damaged proteins and organelles. In human volunteers and animal studies, spermidine levels increase during fasting and calorie restriction, and appears essential for cellular recycling and longevity[Evidence: B][14]. Rapamycin, the most potent autophagy inducer in the protocol, inhibits mTOR and extended lifespan by about 9-14% in mice[Evidence: D][8].
🧪 What to Expect: The Real User Experience
Sensory Profile
NMN powder has a slightly sweet, neutral taste with a faint bitter undertone. Some describe it as "clean" or "metallic-tinged." The fine white powder dissolves easily in water or yogurt but creates a slightly chalky sensation if not fully dissolved. Capsules eliminate taste entirely.
Resveratrol is intensely bitter, astringent, and earthy. Nearly unpalatable alone. The reddish-brown powder has poor water solubility and clumps in liquid. Most users strongly prefer capsules to avoid the prolonged bitter, tannic aftertaste that persists 15-30 minutes.
Berberine powder is bright yellow and intensely bitter. The yellow color stains hands and clothing if spilled. Capsules are essentially mandatory for this supplement.
Common User Experiences
Many people report gastrointestinal discomfort when starting resveratrol at 1g doses. About 20-30% of users experience nausea or diarrhea initially. Berberine causes milder digestive effects than metformin, which is why Sinclair switched. About 40% of new users report some GI adjustment in the first 2 weeks.
The cost is a significant friction point. Quality NMN runs $60-$120 per month for a 1g daily dose. Some users prefer powder over capsules to save $10-$20 per month, accepting the taste trade-off.
Practical Usage Tips
- To improve resveratrol absorption: ALWAYS mix with a fat source (yogurt, olive oil, nut butter). Resveratrol has nearly zero bioavailability without fat
- To reduce resveratrol GI effects: Start with 250mg daily and increase gradually to 1g over 2-4 weeks
- For NMN: Take in morning with full-fat yogurt (Sinclair's method) for better absorption
- For berberine: Take 500mg 2-3 times daily with meals (short half-life requires divided dosing)
- Storage: Keep all supplements in cool, dark, dry place. NMN and resveratrol degrade with light, heat, and moisture
- Starting out: Add one supplement every 2-4 weeks to isolate effects and side effects
Form Preferences
About 60% of users prefer NMN capsules for convenience, while 40% use powder mixed with yogurt to replicate Sinclair's exact method. For resveratrol, 75% prefer capsules to avoid the extreme bitter taste. Berberine is taken as capsules by 95% of users due to bitterness and staining.

⚠️ Risks, Side Effects, and Warnings
The David Sinclair Protocol includes multiple compounds with different risk profiles. Understanding these before starting is essential for safe use.
Side Effects by Supplement
NMN: Generally well-tolerated in studies. No significant adverse effects reported in clinical trials at 300-600mg daily for 12 weeks[Evidence: B][13].
Resveratrol: Gastrointestinal discomfort at 1g doses reported in 20-30% of users. Start low and increase gradually.
Berberine: Mild GI side effects (less severe than metformin). Short half-life requires divided dosing.
Omega-3s: Updated research confirms atrial fibrillation risk at higher doses noted[Evidence: D][9]. Fish burps and digestive upset common.
Drug Interactions
Berberine interacts with medications metabolized by CYP3A4, CYP2D6, and P-glycoprotein. This includes many common drugs. Consult your pharmacist. Resveratrol may interact with blood thinners and medications metabolized by CYP enzymes. Metformin (if still using) reduces B12 absorption with long-term use[Evidence: D][4].
Contraindications
- Pregnancy/breastfeeding: Insufficient safety data for most protocol supplements
- Bleeding disorders: Aspirin and omega-3s increase bleeding risk
- Scheduled surgery: Discontinue aspirin and omega-3s 1-2 weeks before procedures
- Immunocompromised: Rapamycin further suppresses immune function
- Diabetes medications: Berberine may cause hypoglycemia in combination
When to See a Doctor
Seek medical attention immediately if you experience unusual bleeding, signs of infection while on rapamycin, severe stomach pain, or symptoms of low blood sugar (shakiness, sweating, confusion). Schedule a consultation before starting if you take prescription medications, have chronic health conditions, or are over 65.

What to Look for When Choosing David Sinclair Protocol Supplements
Not all longevity supplements are created equal. Here's what matters when selecting quality products:
Quality Markers
- Third-party testing: Look for USP, NSF, or ConsumerLab certification Why it matters: Verifies ingredient accuracy and purity. Supplement industry has no FDA standardization.
- Form used in research: Trans-resveratrol (not cis-resveratrol), β-NMN (not nicotinamide riboside) Why it matters: Clinical studies used specific forms. Bioavailability varies significantly between forms.
- Dosage match: Products should allow reaching studied doses (NMN 300-600mg, resveratrol 500-1000mg daily) Why it matters: Underdosed products can't replicate research benefits.
- Purity testing (HPLC): High-performance liquid chromatography verification for NMN Why it matters: Confirms actual NMN content vs. cheaper precursors or degradation products.
- Minimal additives: Avoid unnecessary fillers, artificial colors, or common allergens Why it matters: Reduces risk of adverse reactions and ensures you're getting active ingredients.
Red Flags to Avoid
- Proprietary blends: Can't verify ingredient amounts. Avoid products hiding doses.
- Unrealistic claims: "Reverse aging," "guaranteed results," "cure" language violates FDA guidelines and suggests poor quality.
- No batch testing: Quality varies without independent verification. Demand certificates of analysis (COAs).
- Suspiciously cheap NMN: Quality NMN costs $50-$100+ per month for 1g daily. Extremely low prices ($20-$30) suggest degraded or mislabeled product.
- Amazon marketplace sellers: High counterfeit risk. Buy from manufacturer websites or verified retailers.
Where to Buy
- Best: Direct from manufacturer websites (ProHealth, DoNotAge, Renue by Science), pharmacies with licensed pharmacists
- Caution: Amazon (verify seller authenticity, check for tamper seals, read recent reviews for quality complaints)
- Avoid: Unregulated websites, pop-up ads, multi-level marketing schemes with unverified claims

What The Evidence Shows (And Doesn't Show)
What Research Suggests
- NMN supplementation significantly elevates blood NAD+ levels in humans[Evidence: A][12]
- Resveratrol produces dose-dependent effects on SIRT1 activation, with strongest effects under 12 weeks[Evidence: A][1]
- Berberine reduces triglycerides by about 0.367 mmol/L and improves multiple metabolic markers comparably to metformin[Evidence: A][10]
- EPA/DHA reduce cardiovascular mortality, coronary heart disease, and myocardial infarction based on 38 RCTs[Evidence: A][5]
- Rapamycin extends lifespan by 9-14% in mice, with the PEARL trial showing tolerability in humans[Evidence: D][8]
What's NOT Yet Proven
- Human lifespan extension: No controlled trials have demonstrated that any protocol extends human lifespan. All longevity claims extrapolate from animal studies or biomarker changes.
- Optimal dosages not established: Studies used varying amounts (NMN 250-1000mg, resveratrol 150-1000mg). Therapeutic thresholds for longevity outcomes remain unknown.
- Combination effects unstudied: No research has evaluated the full Sinclair stack taken together. Interaction effects (positive or negative) are theoretical.
- Long-term safety beyond 12-52 weeks: Most studies lasted 3-12 weeks. Longest rapamycin human data is 1 year[8].
- Young, healthy populations: Most NMN/resveratrol studies enrolled middle-aged or metabolically unhealthy adults. Benefits in healthy 20-30 year olds are unverified.
Where Caution Is Needed
- Omega-3 supplementation increases atrial fibrillation risk by about 24%[Evidence: A][5]. Monitor heart rhythm, especially at higher doses.
- Aspirin bleeding risk increases, particularly in older adults[Evidence: A][7]. Net benefit varies significantly by age and cardiovascular risk.
- Rapamycin immunosuppression poses infection risk[Evidence: D][8]. Only appropriate with physician supervision.
- Resveratrol results inconsistent: 7 studies showed SIRT1 increase, 2 showed decrease, 3 showed no change[Evidence: D][11].
- NMN shows no significant benefit for fasting glucose, insulin, HbA1c, or lipids despite NAD+ elevation[Evidence: A][12].
Should YOU Try This?
Best suited for: Adults over 35 interested in evidence-informed longevity approaches, those willing to monitor biomarkers, individuals with metabolic concerns who have discussed options with their doctor.
Not recommended for: Pregnant or breastfeeding women (insufficient safety data), those on blood thinners or diabetes medications without physician coordination, immunocompromised individuals (rapamycin contraindicated), anyone seeking "proven" lifespan extension.
Realistic timeline: Metabolic effects from berberine may appear within 3-12 weeks[10]. NMN improvements in walking speed and sleep observed at 12 weeks[13]. Long-term aging effects cannot be measured without years of consistent use and biomarker tracking.
When to consult a professional: Before starting any protocol component, especially if you take prescription medications, have chronic health conditions, are over 65, or are considering rapamycin. Regular check-ins to monitor markers every 6-12 months are advisable.
Frequently Asked Questions
Should I take NMN and resveratrol together?
Sinclair takes them together for a reason. NMN provides NAD+ precursors, while resveratrol activates sirtuins that require NAD+ to function. Research shows resveratrol and caloric restriction both increased circulating SIRT1 levels. The combination aims to both fuel (NMN) and activate (resveratrol) longevity pathways simultaneously. Take them together in the morning with full-fat yogurt for optimal absorption of resveratrol.
What time of day should I take NMN?
Sinclair takes NMN in the morning. NAD+ follows circadian rhythms, peaking during waking hours. Morning dosing aligns with your body's natural energy production cycle. Studies used morning dosing protocols. Some users report sleep disruption with evening NMN doses, though this hasn't been formally studied. Taking NMN with breakfast and yogurt also improves consistency and may enhance sublingual absorption for powder forms.
How long does it take to see results from the David Sinclair Protocol?
Timeline varies by individual and has not been definitively established in controlled studies. Research on NMN showed improved walking speed and sleep quality at 12 weeks. Resveratrol SIRT1 activation shows greatest benefit before 12 weeks of supplementation. Berberine metabolic effects appear within 3-12 weeks. Track subjective energy, sleep, and recovery. Consider baseline blood tests for biomarkers.
Can I take the David Sinclair Protocol with my current medications?
Potential interactions have not been comprehensively studied for the full supplement combination. Berberine interacts with medications metabolized by CYP3A4, CYP2D6, and P-glycoprotein, which includes many common drugs. Resveratrol may interact with blood thinners. Omega-3s increase bleeding risk when combined with anticoagulants. Metformin reduces B12 absorption. Always provide your pharmacist with a complete supplement list. This is especially critical if you take diabetes, blood pressure, or blood-thinning medications.
Does David Sinclair take rapamycin?
Yes, but only intermittently under strict medical supervision. Sinclair takes rapamycin approximately 4 times per year. Early research suggests low-dose intermittent rapamycin was tolerated for 1 year with modest biomarker improvements, though significant side effects including infections, insulin resistance, and elevated cholesterol were observed. In animal studies, rapamycin extended lifespan by about 9-14%. Rapamycin is a prescription immunosuppressant with serious risks and should never be used without physician guidance.
What brand NMN does David Sinclair use?
Sinclair has stated he does not endorse specific supplement brands. He receives NMN from his laboratory for personal use. When selecting NMN, look for products with third-party purity testing (HPLC verification), certificates of analysis, and reputable manufacturers. Quality NMN should be β-NMN (the bioactive form) and cost $50-$100+ per month for a 1g daily dose. Extremely cheap products often contain degraded or mislabeled ingredients. See the 'What to Look for When Choosing Supplements' section for detailed quality markers.
What age should you start the David Sinclair Protocol?
There is no established 'ideal' starting age in clinical research. NAD+ levels begin declining in your 30s, which is when some people consider NAD+ precursors. Sinclair has suggested foundational supplements (vitamin D, omega-3s) can be started earlier, with NAD+ boosters potentially appropriate after age 35-40. Younger individuals may benefit more from lifestyle interventions (exercise, fasting, sleep optimization) before adding supplements. The protocol's prescription components (rapamycin) require medical evaluation regardless of age. Consult a physician to discuss your individual situation.
Are there side effects to David Sinclair supplements?
Side effect profiles vary by supplement. Studies suggest NMN supplementation is safe and well-tolerated in healthy middle-aged adults. Resveratrol causes GI discomfort in 20-30% of users at 1g doses. Berberine causes mild digestive effects, less severe than metformin. In people taking omega-3 supplements, atrial fibrillation risk increased by about 24%. Research shows low-dose aspirin increased bleeding risk. Start with lower doses and increase gradually.
