Bryan Johnson's Blueprint Protocol: A Scientific Evidence Review
A rigorous scientific analysis of Bryan Johnson's Blueprint supplement protocol. We evaluate every supplement against clinical evidence.
Lead Science Writer · Peer-Reviewed Sources
Bryan Johnson spends over $2 million per year on his Blueprint longevity protocol. His supplement stack alone includes 50+ compounds. Social media treats this as either genius or madness. Neither take is useful. What matters is: how much of this stack is supported by human clinical evidence?
Strong Evidence
Creatine Monohydrate — 2.5g/day
Over 500 studies support creatine for muscle function. His dose (2.5g) is slightly below the standard 3-5g. Grade: Strong ✅ — but dose may be too low
Vitamin D3 — 2,000 IU/day
The VITAL trial (25,871 participants) showed reduced autoimmune disease risk. Grade: Strong ✅
Omega-3 (EPA/DHA)
REDUCE-IT showed 25% cardiovascular risk reduction with high-dose EPA. Grade: Strong ✅
CoQ10 / Ubiquinol
Q-SYMBIO trial: 43% reduction in major cardiac events. Grade: Moderate-to-Strong ✅
Moderate Evidence
Lithium Orotate — 1mg/day
Epidemiological data links trace lithium to lower dementia rates. But clinical trials at supplemental doses are very limited. Grade: Emerging ⚠️
NMN/NR
Human trials show reliable NAD+ increase. No human longevity data. Grade: Emerging ⚠️
Ashwagandha
Consistent cortisol reduction (11-32%). WHO liver toxicity alert warrants cycling. Grade: Moderate ✅ with cycling
Speculative
Rapamycin — periodic dosing
Extended mouse lifespan 9-14% (NIA ITP). It is an immunosuppressant drug, not a supplement. No human longevity trials. Grade: Speculative ❌ — premature for self-experimentation
Metformin — off-label
TAME trial underway. MASTERS trial showed it may impair exercise adaptations. Grade: Emerging ⚠️
Taurine
2023 Science paper: mouse lifespan +10-12%. Human longevity data needed. Grade: Emerging ⚠️
Senolytics (Fisetin, Quercetin, Spermidine)
Mechanistically interesting but very limited human evidence. Grade: Speculative ⚠️
The Scorecard
| Supplement | Evidence | Verdict |
|---|---|---|
| Creatine | Strong | ✅ Increase dose to 5g |
| Vitamin D3 | Strong | ✅ Appropriate |
| Omega-3 | Strong | ✅ Appropriate |
| CoQ10 | Moderate-Strong | ✅ Good evidence |
| Lithium | Emerging | ⚠️ Unproven at this dose |
| NMN/NR | Emerging | ⚠️ NAD+ rises, longevity unproven |
| Rapamycin | Speculative | ❌ Premature |
| Metformin | Emerging | ⚠️ May impair exercise |
| Taurine | Emerging | ⚠️ Promising |
| Senolytics | Speculative | ⚠️ Trials pending |
Bottom Line
About 40% of Johnson's stack has strong-to-moderate evidence. About 30% is emerging. About 30% is speculative. You can capture most evidence-based benefits with 5-6 supplements under $100/month.
