Bryan Johnson, a California-based technology investor known for his unconventional approach to health and longevity, has expressed uncertainty about the extent of his quest to defy aging following a recent diagnosis of an autoimmune disease. The 48-year-old entrepreneur revealed on social media that he is grappling with autoimmune gastritis, a chronic and incurable condition affecting the stomach lining, prompting him to reconsider his longevity efforts.
Johnson has become widely recognized for his extensive commitment to extending human life through a combination of rigorous health monitoring, experimental therapies, and a restrictive lifestyle regimen. Over several years, he has invested approximately $10 million in research and medical protocols aimed at reversing the biological effects of aging. His strict routine includes taking more than 100 daily supplements and prescriptions, following a plant-based diet limited to a six-hour eating window in the early morning, and exercising for up to 90 minutes every day.
In recent months, Johnson ignited controversy with claims that he successfully cloned himself as a newborn to harvest organs for potential anti-aging purposes. Utilizing induced pluripotent stem cells derived from his own blood, he has explored lab-based cell therapies as part of what he calls “Project Blueprint Protocol.” This work is intended to open new avenues in regenerative medicine, although it has drawn skepticism and ethical questions. Johnson described the cloning effort as a “frontier of new paths” but acknowledged it might evoke fears of a “dystopian future.”
His unconventional lifestyle also involves detailed public disclosures about his own bodily functions and interventions, such as monitoring microplastic content in his sperm and consuming his son’s blood plasma for perceived health benefits, referring to his son as his “blood boy.” To reduce microplastic levels in his semen, Johnson follows an unusual routine of spending 20 minutes daily in dry saunas combined with applying ice packs to the groin area.
Despite the intensity of his longevity pursuits and public commitment to pushing the boundaries of medical science and lifestyle optimization, Johnson’s recent health setback suggests a potential reevaluation of the risks and limits associated with extreme anti-aging measures. His candid reflection marks a rare moment of vulnerability from a figure often characterized by bold experimentation in the pursuit of extended life.
