Bryan Johnson’s Blueprint Explained: What the research Says About Each Part

What is Blueprint?

Bryan Johnson is a US tech entrepreneur who has made slowing his own biological ageing a very public, very expensive project. "Blueprint" is both his published routine and the brand that sells his supplements and foods. His slogan is "Don't Die".

The protocol on his website has changed over time. As of October 2026 it includes:

• Diet: about 2,250 calories a day (described as 10% below his recommended intake), around 130g protein, last meal around midday, built around vegetables, black lentils, nuts, berries, cocoa and extra virgin olive oil. Earlier versions were fully vegan at lower calories.
• Exercise: about six hours a week: three strength sessions, three cardio sessions, plus balance and mobility, and short movement breaks every 30 minutes.
• Sleep: in bed by 8:30pm, screens off an hour before, cool bedroom, no caffeine for 8 to 10 hours before bed.
• Supplements: his branded multi-nutrient capsules, antioxidants, ashwagandha and rhodiola, 800mg EPA/DHA, a longevity powder, 5g creatine and prebiotic fibres.
• Prescription medicines: including metformin, acarbose, tadalafil, empagliflozin (Jardiance), candesartan, evolocumab (Repatha), oral minoxidil and thyroid hormones.
• Light, heat and devices: morning bright light, red and near-infrared light, daily sauna, hyperbaric oxygen courses and shockwave therapy.
• Testing: blood tests every three to six months, an annual full-body MRI, and daily body composition tracking.
• Experimental therapies he reports having had: follistatin gene therapy (2023), stem cell injections (2024), young plasma from his son and rapamycin (stopped in 2024).

His team say these choices are guided by data. Critics, quoted in Scientific American in June 2026, point out that a single person's measurements cannot show whether any of it extends life.

What does it claim to do?

Johnson claims Blueprint has slowed his pace of ageing and reversed several "biological ages": he reports excellent muscle and bone density percentiles, low blood pressure, better skin and perfect sleep scores. The wider claim is that copying the protocol, or buying the products, will help others live longer and healthier lives.

What does the evidence show, part by part?

Exercise: the strongest part

A pooled analysis of 661,137 adults found that meeting the minimum activity guideline was linked to most of the longevity benefit, with gains levelling off at three to five times the minimum. Johnson's six hours a week sits in that range. Strength training is especially valuable as you age. This is the part of Blueprint most worth copying.

Diet: right direction, unnecessary precision

The core foods (vegetables, legumes, nuts, berries, extra virgin olive oil) match the pattern tested in PREDIMED, where a Mediterranean diet supplemented with olive oil or nuts reduced major cardiovascular events compared with a reduced-fat diet in people at high risk. The CALERIE trial found two years of moderate calorie restriction reduced several heart and metabolic risk factors in young, non-obese adults. Nothing suggests his exact recipes, branded products or precise gram targets add benefit beyond those principles. Very early final meals may not suit people with families or shift work, and there is little evidence the timing itself matters much.

Sleep: regularity matters

In UK Biobank data, people with the most regular sleep patterns had a lower risk of death than those with the least regular, and regularity predicted risk better than sleep length. This is observational, so it cannot prove cause, but a consistent bedtime is free and low risk. You do not need an 8:30pm bedtime; consistency is the point.

Supplements: a few useful, many unproven

Creatine has strong evidence for strength and muscle when combined with training (see our creatine guide). Fish oil has mixed evidence for heart outcomes (see our omega-3 guide). Ashwagandha, rhodiola and the various antioxidant blends have small, short trials and none on lifespan. In the UK, most people should also follow NHS advice on vitamin D in winter.

Prescription drugs: not a template

Many of the medicines listed treat specific conditions: blood pressure, cholesterol, blood sugar, thyroid function or hair loss. Taking them without that condition, or for "longevity", is off-label and carries side effects. Metformin's potential as an anti-ageing drug has not been confirmed by a completed trial in healthy people. In the UK, these are prescription-only medicines for good reason.

Rapamycin: stopped after side effects

Rapamycin is an immune-suppressing drug that extends lifespan in mice. The small PEARL trial found low intermittent doses were relatively well tolerated over a year, with some benefits in women only, and several authors work for a company selling rapamycin. According to Scientific American, Johnson stopped in September 2024 after skin infections, raised glucose and blood fats and a higher resting heart rate.

Young plasma and gene therapy: no evidence, real risk

The US FDA has warned that young plasma infusions have no proven clinical benefit for ageing and carry risks. Follistatin gene therapy and stem cell injections for healthy ageing have no published human efficacy trials; Johnson's results are his own reports.

Testing: useful in moderation

Regular blood tests every three to six months and an annual full-body MRI generate a lot of numbers. For healthy people, more scans and tests can turn up harmless findings that lead to anxiety and further procedures. In the UK, the free NHS Health Check is offered to adults aged 40 to 74 without existing heart, kidney or diabetes diagnoses.

Who might reasonably try parts of it?

Almost anyone can safely adopt the foundations: more movement and strength training, a regular sleep routine, a mostly plant-based diet built on olive oil, legumes, nuts and vegetables, and not smoking. These parts cost little and have the best evidence.

Who should be careful?

• Anyone considering prescription drugs, peptides or injections from the protocol: these need a doctor who knows your history.
• People with a history of disordered eating: strict calorie targets and rigid food rules can be harmful; speak to your GP.
• People on blood thinners or with heart rhythm problems: check before adding fish oil or other supplements.
• Anyone offered young plasma, gene therapy or stem cells abroad: these are unregulated for this use and carry real risks.
• People with heart or lung conditions: check with a doctor before daily high-heat sauna or hyperbaric oxygen.

If you want to try it: what to keep and what to skip

Bottom line

Strip away the drugs, devices and branded products and Blueprint's core is advice your GP would give: move a lot, lift weights, sleep regularly, and eat mostly plants with olive oil and nuts. Those parts are well supported and cheap. The experimental layers are unproven, some are risky, and Johnson's dramatic results come from one highly motivated, closely monitored person, which tells us little about what would happen to anyone else.
