Longevity Protocols 2026 — Sinclair vs Attia vs Bryan Johnson + 19 Supplements Graded

BEST PROTOCOL 2026 by use case: BEST EVIDENCE-BASED + FAMILY-FRIENDLY: PETER ATTIA Outlive 4-horsemen + zone 2 cardio + grip strength + 4 strength sessions/week + sleep optimization. $150/mo monthly cost. Most-supported by RCT evidence. BEST FOR LIMITED BUDGET ($50-100/mo): RHONDA PATRICK + DON LAYMAN combo — sauna 4x/wk + protein 1.6g/kg + creatine + omega 3 + vitamin D3. BEST FOR MAXIMAL BIOMARKERS: BRYAN JOHNSON BLUEPRINT — IF you have $1,500-$2,000/mo + extreme discipline + medical supervision. ~100 supplements. Bedtime 8:30PM. Most expensive but generates extensive biomarker data. BEST FOR NAD+ FOCUS: DAVID SINCLAIR pattern — NMN/NR + resveratrol + metformin (off-label) + senolytic combo. Controversial in academic community 2024+ but popular. $250/mo. BEST FOR INTEGRATIVE/MEDITATION: PETER ATTIA + MEDITATION STACK. Add 20min/day Headspace/Calm + sleep optimization. RECOMMENDATIONS BY GOAL: HEALTHY SPAN (40-65) — Peter Attia. AGGRESSIVE BIOLOGICAL-AGE REVERSAL — Bryan Johnson Blueprint (with medical oversight). CHEAP + EVIDENCE-BASED — Rhonda Patrick + Don Layman protein. SLEEP-FOCUSED — Andrew Huberman morning sunlight + magnesium + magnesium L-threonate + apigenin + cool dark room. FUTURE-FOCUSED + DAMAGE-REPAIR — Aubrey de Grey approach (minimize current intervention, wait for therapies). NUTRITION + FASTING — Valter Longo FMD quarterly + plant-forward Mediterranean. AVOID: blindly following any single protocol without testing baseline biomarkers. Get bloodwork, fasting glucose, lipid panel, HbA1c, CRP, omega-3 index, vitamin D first. Then optimize protocol to YOUR biomarker gaps.

DAVID SINCLAIR PROTOCOL 2026 (Harvard professor, lab director, published "Lifespan" 2019, multiple TED talks): SUPPLEMENT STACK: NMN (Nicotinamide Mononucleotide) 1g/day morning. NR (Nicotinamide Riboside) 1g/day morning, alternative NAD+ precursor. RESVERATROL 1g/day with yogurt or olive oil for absorption (poor solubility). METFORMIN 800mg-1g/day off-label (originally diabetes drug). VITAMIN D3 4,000-6,000 IU/day. QUERCETIN (senolytic) 500mg/day. SPERMIDINE 1mg/day from wheat germ. VITAMIN K2 90mcg/day. LIFESTYLE: ONE MEAL A DAY (OMAD) — 16:8+ time-restricted eating. COLD PLUNGE 2-3x/week. SAUNA 4x/week. MINIMAL ALCOHOL. CONTROVERSIES 2024-2026: (1) NMN FDA warning Feb 2022 (later reversed) — manufacturers warned about marketing claims. (2) Lab paper retraction July 2024 (sirtuin pathway claims). (3) LIFEFORCE company conflict-of-interest (Sinclair sold supplements he researched). (4) Mainstream gerontology community skeptical of resveratrol claims (low bioavailability + inconsistent trials). (5) Metformin RCT in healthy adults inconclusive. EVIDENCE LEVELS: NMN — moderate human RCT data showing NAD+ rise. Effect on lifespan in humans unproven. NR — better safety profile, similar NAD+ increase. RESVERATROL — animal lifespan extension fails to replicate consistently in humans. METFORMIN — strong evidence in diabetics; off-label longevity benefits modest. COST: ~$250/month for full Sinclair stack. RECOMMENDATIONS 2026: Sinclair protocol RISKIER than Attia. NMN/NR/resveratrol may help, may be inert. Metformin worth blood-sugar-eligibility discussion with doctor. SAFER alternative: lower-cost Patrick + Attia protocol covers most evidence-based components without speculative resveratrol/sirtuin claims.

PETER ATTIA "Outlive" protocol 2026 (UCSF MD, Stanford trained, "The Drive" podcast, "Outlive" book 2023 NYT bestseller): CORE FRAMEWORK = "4 HORSEMEN" (top 4 causes of death post-50): cardiovascular disease, cancer, neurodegenerative disease, metabolic dysfunction. INTERVENTION PILLARS: (1) STRENGTH TRAINING 4x/week — heavy compound lifts (deadlift, squat, press). Grip strength as proxy for healthspan. (2) ZONE 2 CARDIO 3-4 hrs/week — moderate intensity (~60-70% max HR) — sustain conversation. Builds mitochondria. (3) VO2 MAX TRAINING 1-2x/week — high-intensity intervals. Top 25% VO2 max for age = 4x lower mortality vs bottom 25%. (4) SLEEP OPTIMIZATION — 7-9 hrs, dark cool room, 8 PM blue-light off, magnesium L-threonate before bed. (5) NUTRITION — adequate protein (1.6 g/kg lean mass), Mediterranean-leaning, AVOID processed seed oils. (6) RAPAMYCIN (off-label, with medical oversight) — 5-10mg once weekly for some. mTOR pathway modulation. (7) STATINS or PCSK9-i — for elevated ApoB; LP(a) testing. (8) BLOODWORK — extensive panels every 6 months: lipid sub-fractions, ApoB, LP(a), HbA1c, fasting insulin, CRP, omega-3 index, hormone panel, vitamin D, B12, ferritin. SUPPLEMENTS (minimal): Vitamin D3 5,000 IU, Magnesium L-Threonate 200mg before bed, Omega 3 (EPA+DHA) 2g, Methylated B vitamins. Sometimes Rapamycin (Rx). EVIDENCE: very strong overall. Zone 2 cardio + strength training + sleep have RCT support. Rapamycin off-label is the most experimental component. COST: $100-150/mo supplements. Bloodwork twice yearly $400-1,500 depending on insurance. Trainer or gym membership. ENDORSEMENT 2026: most evidence-based of major researchers. Best for adults 40+. Not flashy or contrarian; mostly applied physiology.

BRYAN JOHNSON BLUEPRINT 2026 (entrepreneur, "Don't Die" documentary, Blueprint book + protocol): GOAL: maximum biological-age reversal via every plausible intervention. SUPPLEMENT STACK: ~100 daily supplements organized by timing (morning/midday/evening). KEY: NMN 1g, NR 1g, Resveratrol 1g, Spermidine 5mg, Vitamin D3 6,000 IU, Pterostilbene 100mg, Glycine 3g + NAC 600mg before bed, Curcumin 500mg with piperine, MCT oil, Allulose (low-glycemic sugar substitute), 17β-Estradiol HRT (rescent — for biomarker-only, not gender-affirming purposes), plus 90+ more. STOPPED: Rapamycin Dec 2024 (Bryan reports it caused systemic inflammation). DIET: 2,250 calories/day + specific timed feeding. Eats by 11AM, fasts after. Plant-forward + olive oil + nuts + leafy greens + animal protein moderate. Strict timing. SLEEP: bed 8:30PM. Wake 5AM. Sleep tracking with Whoop + Oura. Cool dark room. Specific bedtime ritual. EXERCISE: 60+ minutes daily. Strength 4x/week + cardio + flexibility. BLOODWORK: monthly biomarker testing — fasting glucose, lipids, hormones, inflammation markers, biological age via DunedinPACE + GrimAge + PhenoAge clock. CONTROVERSIES: (1) Son's blood plasma transfusion (2023) — withdrew this practice after public backlash. (2) Honduras gene therapy 2023 — followers concerned about supervision. (3) "Don't Die" 2025 Netflix documentary normalized extreme protocols, drawing critique. (4) Personality cult dynamic — Blueprint as religion. EVIDENCE LEVELS: MIXED. Some Blueprint elements have solid evidence (sleep optimization, protein timing, exercise). Others are speculative (full supplement stack). Bryan reports his biological age tracking SLOWED but real-world health span data unavailable. COST: ~$1,500-$2,000/MO supplements. Plus tests + trainers + cooking + extreme time. WHO IT IS FOR: extremely-disciplined high-net-worth individuals with biomarker obsession. NOT FOR: most people. CRITICISM: most longevity researchers (Attia, Sinclair himself, de Grey) say Blueprint is "throwing kitchen sink at problem". Not all interventions stack additively. Some may interact negatively. RECOMMENDATIONS 2026: Blueprint extreme. Most evidence-based components (sleep + exercise + protein + bloodwork) achievable WITHOUT $2k/mo supplements. If interested, study WHICH specific elements have evidence vs are speculative. Don't copy whole protocol blindly.

NAD+ STACK SCIENCE 2026: WHY NAD+: Nicotinamide Adenine Dinucleotide is critical for mitochondrial function + DNA repair + sirtuin activation. NAD+ levels DECLINE with age (40-60% lower at 70 vs 20). NAD+ PRECURSORS: NMN (Nicotinamide Mononucleotide), NR (Nicotinamide Riboside), Niacin (vitamin B3). Each can raise NAD+ in cells. EVIDENCE FOR HUMAN BENEFIT: NMN: Multiple human trials show NAD+ rise in plasma + tissues. Some show insulin sensitivity improvement. Few show actual lifespan/healthspan benefit. NR: Similar to NMN. Tru Niagen brand has most extensive RCTs. Showed NAD+ rise + some metabolic markers. Lifespan extension unproven in humans. RESVERATROL: Cell + animal data suggested NAD+ + sirtuin activation. Human bioavailability poor (poor absorption + rapid metabolism). MOST trials disappointed when scaled to humans. Trans-resveratrol better than regular but still struggle. NIACIN (vitamin B3): cheap, effective NAD+ precursor BUT causes "niacin flush" (skin redness) at doses needed. METABOLIC SAFETY: NMN — was given FDA warning 2022 (later relaxed). Generally well-tolerated up to 1g/day. NR — strong safety profile, FDA-approved as supplement. RESVERATROL — generally safe but low absorption frustrates effects. STACKING: NMN/NR + Resveratrol theoretical synergy via sirtuin activation. Animal data supports. Human data thin. COST: NMN/NR $50-100/mo for 1g/day. Resveratrol $20-40/mo. Combined $80-150/mo. CRITICAL TAKE 2026: NAD+ rises with supplementation. WHETHER raised NAD+ extends life-span/health-span in humans unproven. Some evidence for fatigue + insulin sensitivity. Lifespan claims SPECULATIVE. Anti-aging benefits MAYBE. RECOMMENDATIONS: Worth considering for adults 50+. Choose NR over NMN (better regulatory safety). Choose Tru Niagen brand or third-party-tested generic. Trans-resveratrol form > regular. Don't expect dramatic anti-aging results. Don't skip exercise + sleep + diet for supplements.

RAPAMYCIN OFF-LABEL LONGEVITY 2026: BACKGROUND — Rapamycin (Sirolimus) is FDA-approved IMMUNOSUPPRESSANT for organ transplant patients. mTOR-inhibition mechanism. ITP (Interventions Testing Program at NIA) showed CONSISTENT lifespan extension in mice across labs. Most-replicated longevity intervention in animals. HUMAN OFF-LABEL: prescribed by some longevity clinics (Boston, NYC, Bay Area, Austin) for 5-10mg once weekly (vs daily transplant doses). DOSE PATTERN: weekly intermittent to avoid immunosuppression. Some clinics use 5mg weekly (1/2 tab), 10mg weekly (full tab). EVIDENCE IN HUMANS: limited but growing. PEARL TRIAL — Phase 2 RCT showed elderly subjects on 5mg weekly improved muscle strength + glucose response. Other small trials show similar. NO LARGE-SCALE LONG-TERM HUMAN MORTALITY DATA. Off-label use considered "experimental" by mainstream medicine. SAFETY: Side effects at off-label longevity doses: mouth ulcers (~30% of users), GI upset, slight increase in infections, lipid panel changes. Less severe than transplant-dose. STOPPED USES: Bryan Johnson stopped Rapamycin Dec 2024 — reported systemic inflammation. Some users stopping due to mouth ulcers. WHO PRESCRIBES OFF-LABEL: Specialized longevity clinics — Healthspan Solutions, Tally Health, Healthspan AI, Healthspan Health. Telehealth: AgelessRx, Renue (selected states). Cost: $150-400/month including consult + Rx. RECOMMENDATIONS 2026: Rapamycin RESTRICTED EXPERIMENTAL. Best for: (1) Adults 50+ with strong evidence-based lifestyle (sleep, exercise, nutrition, stress) already optimized. (2) Working with experienced clinician (NOT random telehealth). (3) Acceptance of unknown risks for unproven benefit. NOT FOR: (1) Pregnancy/nursing/trying to conceive (immunosuppression). (2) Active infection. (3) Recent vaccines (timing important). (4) Cancer history. (5) Surgery scheduled (requires hold). (6) Most healthy adults under 50 (low marginal benefit). PERSONAL CONSIDERATION: If you wouldn't spend $200/mo on lifestyle (gym, food, sleep equipment), don't spend it on Rapamycin. Lifestyle matters more.

EVIDENCE-BASED LONGEVITY SUPPLEMENTS 2026 (graded A-C): GRADE A (strong human RCT evidence + biological mechanism): OMEGA 3 (EPA+DHA) 2-3g/day combined — strongest cardiovascular + cognitive aging evidence. Test omega-3 index for personalization. VITAMIN D3 — 70%+ of US adults insufficient. Test 25-OH levels, target 40-60 ng/mL. CREATINE 5g/day — strongest muscle + cognition evidence in healthy adults. Cheap. No downside. MAGNESIUM glycinate or threonate — 70% of Americans deficient. Sleep + muscle + nerve. PROTEIN INTAKE 1.6 g/kg lean body mass for 50+ — sarcopenia prevention + recovery. GRADE B (moderate human + strong animal evidence): METHYLATED B VITAMINS especially B12 — critical for 25% with MTHFR mutations. Test homocysteine. SULFORAPHANE (broccoli sprouts/Avmacol) 50-100mg — phase 2 anti-cancer activation. Hot 2024-2026 research field. NMN 500mg-1g/day or NR 300-1g/day — NAD+ precursors. Some metabolic + insulin sensitivity benefit. Lifespan unproven in humans. CURCUMIN with piperine — anti-inflammatory. Liposomal form for bioavailability. NAC 600-1,200mg — glutathione precursor. Lung + liver. GLYCINE 3g before bed — sleep onset + temperature. SPERMIDINE 1-3mg/day — autophagy. From wheat germ naturally. GRADE C (animal data only OR observational): RESVERATROL — animal lifespan benefit fails to translate to humans. Better trans-resveratrol form but bioavailability struggles. PTEROSTILBENE 50-150mg — better-absorbed resveratrol cousin. Limited human trials. QUERCETIN 500-1,000mg — senolytic with dasatinib in animal trials. Human data thinner. APIGENIN 50mg — light evidence for sleep. RAPAMYCIN (off-label Rx) — strongest mTOR-inhibition in animals. Off-label human use experimental. METFORMIN (off-label) — strong diabetes outcomes. Off-label longevity benefit modest. May blunt exercise gains. TONGKAT ALI 200-400mg — testosterone-boosting claims in some male trials. Quality varies. AVOID OR DEPRIORITIZE: HGH (Human Growth Hormone) — risks > benefits in healthy adults. TOO MUCH IRON — pro-aging in non-deficient adults. PROPRIETARY BLENDS — most don't list dosages. RECOMMENDATIONS 2026: Start with GRADE A (omega 3, vitamin D, creatine, magnesium, protein). Add GRADE B based on personal goals + biomarkers. Be skeptical of GRADE C unless evidence strengthens. Spending >$200/month on supplements at age 35 is questionable; >$500 likely waste vs investing in sleep/exercise/food.

LONGEVITY BLOODWORK 2026 — comprehensive panels: BASELINE TEST (annually after 35, semi-annually after 50): COMPREHENSIVE METABOLIC PANEL — fasting glucose, electrolytes, kidney + liver function. STANDARD LIPID PANEL — total + LDL + HDL + triglycerides. ADVANCED LIPID — APOB (apolipoprotein B) — better mortality predictor than LDL. LP(A) (Lipoprotein-A) — genetic risk factor, test once. LDL particle number + size if elevated. INFLAMMATION — hsCRP (high-sensitivity C-reactive protein), homocysteine, fibrinogen. GLYCEMIC — HBA1C, fasting insulin, fasting glucose, 2-hr post-meal glucose if at-risk. HORMONES (full panel): testosterone (total + free + SHBG), DHEA-S, cortisol AM/PM, TSH + free T3 + free T4 + reverse T3. Estradiol if relevant. NUTRIENTS: VITAMIN D 25-OH, B12 + folate, methylmalonic acid (B12 deficiency marker), homocysteine. FERRITIN + IRON (avoid excess iron in non-deficient). INFLAMMATION SUBSET: HOMOCYSTEINE (B12/B6/folate marker), URIC ACID, GGT (oxidative stress marker). EMERGING: OMEGA 3 INDEX (EPA+DHA fraction of total fatty acids — target 8%+). BIOLOGICAL AGE CLOCKS — DunedinPACE (Dunedin), GrimAge, PhenoAge. COVERED BY INSURANCE: standard panels usually. Advanced (ApoB, LP(a), homocysteine, etc.) require physician order or out-of-pocket. SELF-SERVE: Function Health $499/yr, Inside Tracker $299, Quest Health, Lab Corp Direct. INSURANCE: most insurers cover basic panels with deductible. Some advanced tests not covered without indication. 5-PANEL ESSENTIAL: ApoB, LP(a), HbA1c, hsCRP, omega-3 index. Add lipid + metabolic + thyroid + vitamin D. ~$200-$500/year via direct lab. INTERPRETATION: lipid + metabolic + inflammation form bulk of mortality risk picture. Track over time. Optimization improves cardiac + metabolic health which drives life expectancy. WHEN TO TEST: ANNUAL after 35. SEMI-ANNUAL after 50. QUARTERLY after major intervention (new statin, hormone change, supplement protocol shift).
