📊 Sinclair / Attia Longevity Stack — Timing

Form / Protocol	Dose	Timing	Notes
🥇 Morning fasted	NMN 1g + Resveratrol 500mg (in yogurt/fat)	On waking	NAD+ + Sirtuin activation
✅ With breakfast	Vitamin D3 5000IU + K2 200mcg + Omega-3 3g	With fat	Baseline anti-aging
⚡ Before meals (3x)	Berberine 500mg	Before each main meal	AMPK/metformin-like effect
🧬 Monthly pulse (2 days)	Fisetin 500mg x2 days	With breakfast	Senolytic — clears zombie cells
♻️ Daily	Spermidine 1-2mg (wheat germ)	With food	Autophagy induction

💡 Sinclair’s key principle: “Don’t eat for 16-18 hours before taking NMN — fasting and NMN work synergistically through the same AMPK/sirtuin pathway.”

The Science of Longevity Supplements

Longevity biology focuses on four key hallmarks of aging: telomere attrition, mitochondrial dysfunction, cellular senescence, and epigenetic alterations. The supplement stack below targets each mechanism with specific compounds that have peer-reviewed evidence.

Frequently Asked Questions

What supplements does David Sinclair take daily?

Sinclair has publicly stated his 2023 protocol: 1g NMN morning (in yogurt), 1g resveratrol with fat, 500mg metformin (Rx), vitamin D3, vitamin K2, aspirin 83mg. He also takes quercetin, fisetin, and spermidine. Note: metformin is prescription-only — berberine is the OTC equivalent.

Is the longevity stack safe to take long-term?

The base stack (NMN, resveratrol, omega-3, berberine) has reasonable safety data up to 1-2 years. Fisetin senolytic pulsing (2 days/month) is safer than daily dosing. The honest answer: long-term human longevity data doesn’t exist yet — these are evidence-based bets informed by mechanistic research.

The Evidence-Based Longevity Stack for 2026

Longevity research has moved from theoretical to clinical. Several interventions now have strong mechanistic backing and emerging human data. Here’s what the current evidence supports:

Foundation Longevity Supplements

NMN or NR (500–1000mg/day) — NAD+ precursors. NAD+ declines 50% between ages 40 and 60. Supplementation reverses some aging markers in animal models; human data is accumulating rapidly. David Sinclair’s most-cited intervention.
Resveratrol (500mg/day with fat) — activates SIRT1 sirtuins. Combined with NMN in Sinclair’s personal stack. Fat-soluble: take with olive oil or fatty meal. Trans-resveratrol form only.
Magnesium (400mg glycinate or malate) — 40+ biological processes decline faster with deficiency. The most underrated longevity supplement due to its ubiquity in essential processes.
Vitamin D3 + K2 (3000–5000 IU D3 / 100–200mcg K2) — deficiency dramatically accelerates bone loss, immune dysfunction, and cardiovascular risk.
Omega-3 EPA+DHA (2–3g/day) — the VITAL trial (25,000 participants) showed 28% reduction in heart attack with omega-3 supplementation. Strong telomere preservation data.

Emerging Longevity Interventions

Quercetin + fisetin — senolytic flavonoids (clear senescent “zombie cells”). Intermittent high-dose protocols (500–1500mg for 2–3 days/month) showing promise in early trials.
Spermidine (1–3mg/day) — induces autophagy comparable to fasting. Found in wheat germ, aged cheese. Supplement or food sources both effective.
Berberine (500mg 2x/day) — activates AMPK (same pathway as metformin). Improving metabolic health is foundational to longevity.

Lifestyle Multipliers (Non-Negotiable)

No stack replaces these fundamentals: 7–9 hours sleep, 150+ minutes zone 2 cardio/week, resistance training 2–3x/week, caloric control (slight restriction or IF), and stress management. Supplements enhance a healthy lifestyle; they don’t replace it.

Building Your 2026 Longevity Stack: A Practical Framework

A longevity stack isn’t a single product — it’s a coordinated set of compounds that work on different aging pathways simultaneously. The goal is to cover the four key mechanisms: NAD+ restoration, senolytic activity, anti-inflammation, and mitochondrial support.

Foundation Layer (Daily Non-Negotiables)

These compounds have the strongest evidence base and form the backbone of any longevity stack:

Omega-3 fatty acids (2g EPA+DHA) — reduces systemic inflammation, supports cardiovascular health and cognitive function into old age
Vitamin D3 5000IU + K2 MK-7 200mcg — critical duo for bone density, immune function, and preventing arterial calcification
Magnesium glycinate 400mg — cofactor for 300+ enzymatic reactions including DNA repair mechanisms

Longevity-Specific Layer

NMN 500mg or NR 300mg — NAD+ precursors to counter the 50% NAD+ decline by age 50; take morning with food
Trans-resveratrol 250mg — SIRT1 activator; must be taken with a fatty meal for absorption; stack with NMN for synergistic effect
Spermidine 1-2mg — activates autophagy (cellular “self-cleaning”); found naturally in wheat germ but therapeutic doses require supplementation

Anti-Aging Adaptogens

Ashwagandha 600mg KSM-66 — reduces cortisol (which accelerates cellular aging), improves sleep quality, supports testosterone in men over 40
Lion’s Mane 1000mg — nerve growth factor stimulation; most compelling cognitive longevity compound available OTC

What to Expect and When

Most longevity supplements don’t produce immediate noticeable effects — they work on molecular processes over months to years. You’ll likely notice better sleep (magnesium), improved energy and mental clarity (NMN/NR) within 4-8 weeks, and reduced inflammation markers over 3-6 months.

The real payoff is measured in decades, not weeks. Consistent use creates compounding protection against the cellular damage accumulation that drives age-related disease.

Budget Approach

If cost is a constraint, prioritize: Omega-3 + Vitamin D3/K2 + Magnesium. These three alone provide the foundation at under $40/month. Add NMN when budget allows — it provides the largest single upgrade to a basic longevity stack.

Fisetin Supplement Guide: Senolytic, Brain Health… Quick Answer: Fisetin (100-500mg/day, or 20mg/kg pulse dosing 2 days/month as a senolytic) is a flavonoid found in strawberries that clears senescent cells (zombie cells), activates sirtuins, and crosses the blood-brain barrier to protect neurons. The Mayo Clinic Phase 1 human senolytic trial used fisetin 20mg/kg/day for 2 consecutive days. Compared to quercetin (the other major dietary senolytic), fisetin has dramatically superior bioavailability and a 7-day half-life. Managing fisetin supplement guide: senolytic, brain health and longevity (2026) through targeted nutritional support has become one of the most researched areas in evidence-based medicine. Unlike pharmaceutical interventions, the supplements reviewed in this…

Spermidine Supplement Guide: Autophagy, Longevity… Quick Answer: Spermidine (10-15mg/day) is a natural polyamine found in wheat germ, soybeans, and aged cheese that activates autophagy (cellular self-cleaning) independent of mTOR inhibition. A 2018 Lancet Cardiology study found higher dietary spermidine intake correlated with 5-year longer lifespan in 829 adults. Spermidine declines 40-60% with age, and supplementation restores autophagy capacity in aging tissues. Managing spermidine supplement guide: autophagy, longevity and heart health (2026) through targeted nutritional support has become one of the most researched areas in evidence-based medicine. Unlike pharmaceutical interventions, the supplements reviewed in this guide address underlying deficiencies and metabolic imbalances that often drive symptoms…
