Changed my life

As someone in tech, I spend most of my day sitting or standing at a screen. Since starting Blueprint in 2025, I've lost over 50 lbs and finally feel in control of my health. I can't thank Bryan enough for creating this.

Bringing balance to body and mind

I've been taking Longevity Mix and Essential Capsules consistently for a month. I've noticed that I am more alert, focused, and have better memory. My sleep has also improved. I fall asleep more effortlessly, my sleep is deeper and more rejuvenating.

Mind Blown

I recently purchased Longevity Mix. This product has given me near instant improvements to my mood, sleep, and energy levels throughout the day. Having changed nothing else in my daily routine, I can without a doubt contribute these immediate improvements to Longevity Mix.

Who is Bryan Johnson?

Bryan Johnson is the world's most measured human.

Bryan's best measured epigenetic speed of aging is 0.48 (average 0.5) — ranked #1 of 5,677. He built the protocol that produced those results, then published it openly: the full Bryan Johnson Blueprint protocol, free for anyone to follow.

Before Immortals, he founded Braintree, which acquired Venmo and was sold to PayPal in 2013. Along with Kate Tolo, he is the founder of Immortals and Blueprint.
What wearables does Immortals support?

Immortals supports all major wearables.

Supported devices include Oura, Whoop, Garmin, Eight Sleep, Fitbit, Dexcom, Freestyle Libre, Ultrahuman, Polar, Withings, Google Fit, Strava, Peloton, Wahoo, Hammerhead, Omron, Cronometer, and Beurer. Upload biomarkers from any lab in any format. BryanAI reads it all.
What is longevity medicine?

Most medicine is reactive. You wait for symptoms, then treat the disease.

Longevity medicine measures the biomarkers that signal early risk factors sometimes decades before symptoms develop. The goal of longevity medicine is routine measurement and early intervention to help detect and avoid age-related decline and chronic illness from developing in the first place and extend the years you’re actually healthy. It’s proactive rather than reactive. The tools of longevity medicine are: comprehensive biomarker panels, wearable data, personalized supplementation and prescriptions, and other data-backed longevity interventions.

Immortals is the longevity medicine platform built on Bryan Johnson's protocol.
How much does it cost to follow Bryan Johnson's protocol?

Most of Bryan Johnson's longevity protocol is free. He openly publishes all of his data and protocols on sleep, nutrition, and exercise.

Biomarker panels, longevity medications, and Blueprint supplements are available to purchase through Immortals as optional add-ons, but are not required to follow the protocol.
