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 more than 30 doctors and researchers. 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. Strict vegan, nutrient-dense, with an eating window that ends at 11 AM. Lots of kale, berries, olive oil, nuts. No alcohol, no sugar.

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. Over 100, including rapamycin (off-label, under a doctor's supervision), acarbose, NAC, berberine, and various vitamins. This is the most debated part.

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

6. Experimental stuff. Things like plasma exchange with his son (later stopped), 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.

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](./rapamycin-deutschland) - 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.
