Bryan Johnson & Blueprint, a European View

Bryan Johnson is a US tech entrepreneur, born 1977. He sold Braintree to PayPal for about 800 million dollars. Since 2021 he reportedly puts around 2 million dollars a year into a strict longevity project called Blueprint.

Blueprint is a tightly structured protocol. Johnson built it with a team of doctors and researchers (Blueprint references "67 interventions based on 1,000+ clinical trials"). His stated goal is to measurably slow his biological aging, or as he puts it, to "not die".

Johnson publishes almost everything: his numbers, blood test results, meals, and full supplement list. That openness has given him a huge audience, and also sharp pushback from scientists. Reactions range from "interesting transparent self-experiment" to "PR project with weak evidence".

This guide looks at the protocol neutrally. The goal is to sort out what the research actually supports, what is still experimental, and what a normal person in Europe could realistically borrow from it.

Core parts, as of early 2026:

1. Diet. About 2,250 kcal a day, predominantly plant-based and nutrient-dense, with an early eating window (~5:25 AM first ingestion to a noon cut-off, with the last meal noted around 11:00 AM; earlier iterations used an 11 AM cut-off). The protocol centres on two signature meals: Super Veggie (broccoli, cauliflower, black lentils, shiitake or maitake mushrooms, garlic, ginger, hemp seeds, extra-virgin olive oil, lime, cumin, apple cider vinegar, and 1–4 Tbsp fermented foods such as sauerkraut or kimchi) and Nutty Pudding (originally a home recipe of macadamia/walnuts/chia/flax/berries/pomegranate/cocoa; the current 2026 protocol uses the proprietary Longevity Protein with Blueberry Nut Mix plus 11 g collagen, EVOO, and berries). No alcohol, no sugar. Earlier iterations were labelled strictly vegan; current public documentation shows small amounts of animal-derived ingredients in some versions. Note on the calorie number: 2,250 kcal is not extreme for a typical adult — for Johnson's specific height, weight, and high daily activity, it works out to roughly a 10% deficit. He previously ate closer to 1,977 kcal (~20% deficit) but raised intake after losing too much body fat.

2. Sleep. 8 hours, fixed bed and wake times, cool dark room.

3. Movement. About 1 hour every day. A mix of strength, HIIT, mobility, and balance work.

4. Supplements. Roughly 8–13 capsules/pills daily plus the Longevity Mix powder, Longevity Protein, and prescription items including metformin, tadalafil, Jardiance, acarbose, Repatha (biweekly), Armour Thyroid, and minoxidil. The earlier "100+ pills" figure reflects iterations from 2022–2023. The current stack still includes NAC, berberine, creatine, collagen peptides, vitamin D, omega-3, and a long tail of polyphenols and minerals consolidated into the proprietary Longevity Mix and Essentials capsules. Rapamycin is no longer part of the stack. Johnson took it off-label for roughly five years and publicly discontinued it in late September 2024, citing elevated inflammation markers, lipid abnormalities, and other adverse signals that his medical team judged outweighed the longevity benefits. The remaining large supplement stack is still the most debated piece of the protocol.

5. Monitoring. Frequent blood work, MRI, DEXA, epigenetic age tests, HRV. Johnson publishes the dashboards online.

6. Experimental stuff. Things like the three-generation young-plasma exchange with his father and son (Johnson reported no measured benefit and discontinued it in 2023), gene therapies, intensive skincare. One-off experiments without broad scientific backing.

The parts of Blueprint sit on very different amounts of evidence:

Well supported:

• Regular sleep is associated with strong heart and brain benefits
• Strength plus cardio training is one of the strongest longevity signals we have
• Vegetables and minimal processed food are backed by broad research
• No alcohol and no nicotine is associated with clear drops in mortality

Plausible, but not fully proven:

• Time-restricted eating: human data are mixed
• Calorie restriction in normal-weight adults: strong animal data, moderate human data (CALERIE)
• Rapamycin off-label: strong animal data, early human signals cautiously positive
• Early eating window: signals mostly from observational studies

Speculative to questionable:

• Most supplements beyond vitamin D, omega-3, creatine, and magnesium
• Plasma exchange for "rejuvenation"
• Specific stacks with no check for interactions

The point to hold on to: Blueprint is one case, not a controlled trial. Even if Johnson's markers improve, that doesn't prove any single piece causes the effect. It also doesn't tell us what would happen in someone else.

Morgan Levine's critique: Morgan Levine (lead developer and first author of PhenoAge, one of the clocks Johnson reports on) has publicly stated that commercial epigenetic clocks are not validated to measure "age reversal" in the way Johnson's marketing implies — they respond substantially to short-term inflammation, acute illness, weight-loss states, and recent diet changes, rather than durable rate-of-aging shifts. Johnson's clock-based claims of rolled-back biological age should be read as a clock-response signal, not proof of slowed aging.

If you live in Germany, Austria, or Switzerland and want to borrow from Blueprint, sort the ideas by effect per effort.

High payoff, low effort:

• Sleep hygiene: fixed times, darkness, no evening alcohol
• Strength training 2 to 3 times per week
• 30 to 45 minutes of movement a day
• Minimally processed food, lots of vegetables
• No alcohol, no nicotine

Medium payoff, medium effort:

• Time-restricted eating, 10 to 12 hour window
• Yearly DEXA scan plus a full blood panel
• Basic supplements: vitamin D, omega-3, magnesium, creatine
• A Whoop or Oura for sleep and HRV tracking

High effort, unclear payoff. Go slow:

• Supplement stacks of 50 or more with no interaction check
• Rapamycin off-label, which is legally and medically tricky. See our Rapamycin Germany guide
• Very low calorie intake at a healthy weight
• Plasma exchange, gene therapies

A sensible European version costs roughly €50 to €150 per month: wearable, basic supplements, yearly testing. Not €30,000. Most of the benefit comes from the first 20% of the effort. Classic Pareto.

Top 5 copyable / Top 5 skippable

If you want a shortcut, use this triage:

COPY (cheap, evidence-based, low risk): fixed sleep/wake times, 2-3 strength sessions per week, daily 30+ minutes of movement, a minimally processed plant-forward diet, no alcohol or nicotine.

CONSIDER: TRE with a 10-12h eating window, a D3+K2 + omega-3 + magnesium + creatine stack (~€20-40/mo), yearly DEXA and an expanded blood panel, an Oura / Whoop / Polar for sleep and HRV tracking.

SKIP without medical supervision: stacks of 50+ supplements with no interaction check, very low calorie intake at a healthy weight, plasma exchange or other experimental rejuvenation therapies, off-label prescription drugs without a prescribing physician.

Blueprint for women

Blueprint is calibrated on one male body. Menstruating women experience poorer sleep, HPA-axis disruption, cycle-length changes, and bone loss on very low calorie intake — adapt the eating window and calories for your physiology, prioritise iron and ferritin testing, and keep HRT on the table in perimenopause (see the women's guide). Postmenopausal women get more longevity bang for their buck from strength training and bone-density work than from extreme calorie restriction.

DACH reality check

Importing the Blueprint Stack into the EU can hit customs friction — some ingredients aren't EU-authorised as Novel Food (NMN specifically — see NMN-Germany guide). A realistic European version uses Apotheke or dm/Rossmann-sourced basics: D3+K2, omega-3, magnesium glycinate, creatine, plus an annual DEXA at a Radiologie-Praxis (€50-120).
