Who Is Bryan Johnson?
Bryan Johnson is the founder of OS Fund and Kernel, and the person who sold Braintree/Venmo to PayPal for $800 million. Since 2021, he's been the subject of a self-funded project called Blueprint — an attempt to reverse his biological age using the most rigorous possible protocol.
His team of 30 medical professionals runs daily blood tests, MRI scans, ultrasounds, and biomarker panels to optimize every measurable aspect of his biology.
In 2023, his measurements placed his biological age at approximately 37 — despite being chronologically 46.
The Core Protocol
Diet
Johnson eats approximately 1,977 calories/day in a strict vegan, whole-foods pattern. His meals are heavily engineered:
- Super Veggie Bowl: black lentils, broccoli, cauliflower, mushrooms, garlic, ginger, olive oil, hemp seeds
- Nutty Pudding: macadamia milk, flaxseed, berries, walnuts, sunflower seeds, pomegranate
- No alcohol, no processed food, no eating after 11am
He practices time-restricted eating (2-meal window, roughly 6am–11am).
Sleep
Johnson considers sleep his highest-leverage intervention:
- Strict 9pm bedtime, every night
- 8.5 hours in bed target
- Temperature-controlled mattress (Eight Sleep)
- No light exposure after sundown
- Blue-light blocking glasses
- Regular HRV tracking
Exercise
- 1 hour per day, every day — no rest days
- Rotation of Zone 2 cardio, resistance training, functional movement
- High-intensity intervals 2–3x/week
- Grip strength and VO₂ max tracked quarterly
Supplements
Johnson takes 111 supplements per day across multiple stacks:
- Core longevity: NMN, NR, resveratrol, spermidine, fisetin, quercetin
- Metabolic: metformin, DHEA, testosterone (microdosed)
- Neural: lion's mane, lithium (trace), B12 methylated
- Protective: lycopene, lutein, zeaxanthin
What the Data Shows
After 18 months of Blueprint, Johnson's team published measurements showing:
- Epigenetic age: ~5 years younger than chronological
- Heart age: 37 (actual age: 46)
- Lung capacity: top 1.5% for his age
- Inflammation (hsCRP): effectively zero
- Skin quality: comparable to 28-year-olds by one metric
These are extraordinary results — but they come with $2M/year, full-time commitment, and an 8-person support team.
What's Actually Worth Copying
The good news: most of Johnson's results come from behaviors that cost almost nothing:
1. Strict sleep schedule — The highest-ROI habit he has. A consistent sleep/wake time is free and has outsized effects on biological aging.
2. No alcohol — Johnson's team estimates alcohol accounts for a measurable portion of the biological aging they see in patients.
3. Time-restricted eating — Eating in a window (even just skipping late-night snacking) activates autophagy pathways with no financial cost.
4. Zone 2 cardio — 45–60 minutes at moderate intensity, 3–4x/week. This is the most evidence-backed intervention for cardiovascular biological age.
5. Whole foods, high fiber — The gut microbiome is increasingly recognized as a biological aging driver. Johnson's plant-heavy diet optimizes this.
The Ageless Perspective
You don't need $2 million. The behaviors that drive most of Johnson's measurable results are accessible to anyone willing to be consistent.
Ageless is built to give you the same data-driven feedback loop Blueprint uses — starting with your actual biomarkers and tracking your real progress over time.
