After leaving Braintree, Johnson focused on scientific innovation. He founded Kernel, a neurotechnology company developing devices that measure brain activity. He also launched OS Fund, which invests in startups advancing artificial intelligence, biotechnology, and space technology.
In 2021, Johnson introduced Project Blueprint, later evolving into the broader Don’t Die movement. The program combines nutrition, exercise, sleep, medical testing, and continuous data tracking to improve long-term health. Johnson regularly updates the protocol as new scientific evidence emerges, while emphasizing that many experimental interventions still require additional research.
Johnson’s work reached a wider audience through the 2025 Netflix documentary Don’t Die: The Man Who Wants to Live Forever. In 2026, he disclosed that doctors diagnosed him with autoimmune gastritis, a chronic condition affecting the stomach lining. He continues sharing his treatment journey while supporting evidence-based longevity research.
As of 2026, Bryan Johnson remains a leading voice in longevity science, health optimization, and biohacking. Although some experts question his more ambitious claims, his emphasis on sleep, exercise, nutrition, and health monitoring has sparked global conversations about extending healthy lifespan.

Following his divorce, he became engaged to internet personality Taryn Southern, but they later ended their engagement. In December 2025, Johnson publicly confirmed his long-term relationship with Kate Tolo, his Blueprint co-founder. As of 2026, the couple remains together, but they have not announced a marriage or engagement. Johnson continues collaborating with Tolo on longevity research and the Don’t Die movement.
Bryan Johnson First Wife | Ex-Wife
Bryan Johnson was previously married, but he has never publicly revealed his first wife’s identity. As a result, her name remains unconfirmed in reliable public records. The former couple has three children, and Johnson has consistently kept his ex-wife out of the public spotlight.

After the divorce, Johnson became engaged to Taryn Southern, although she was his fiancée, not his wife. As of 2026, no verified source identifies Bryan Johnson’s first wife by name, and claims circulating online remain unsubstantiated.
Bryan Johnson Children
Bryan Johnson has three children from his previous marriage. However, he has chosen to keep most details about their lives private. His oldest publicly known child is Talmage Johnson, who has occasionally participated in his father’s longevity research and health experiments. Johnson has also referenced another son, Jefferson, in public posts. However, he has not publicly identified his third child. Despite sharing parts of his family life, Johnson prioritizes his children’s privacy. As of 2026, he continues balancing fatherhood with his work on Blueprint, Kernel, and the Don’t Die movement.
Bryan Johnson Family | Parents, Siblings, and Early Life
Bryan Johnson was born on August 22, 1977, in Provo, Utah, and grew up in nearby Springville, Utah. He is the middle child in his family and has one brother and one sister. After his parents divorced during his childhood, Johnson lived primarily with his mother and stepfather, who owned a trucking company. Johnson has not publicly disclosed the names of his parents or siblings on his official platforms. Although some media reports have identified family members by name, Johnson has not verified those details himself. As of 2026, he continues to keep much of his family life private while focusing on entrepreneurship, Blueprint, and longevity research.
Bryan Johnson Anti-Aging | Blueprint, Biohacking, and Longevity Protocol
Bryan Johnson’s anti-aging strategy centers on his Blueprint protocol, a data-driven program designed to slow biological aging and improve long-term health. Since launching Project Blueprint in 2021, Johnson has followed a highly structured routine that includes a strict plant-based diet, daily exercise, optimized sleep, frequent blood tests, whole-body imaging, and continuous biomarker tracking. He has publicly stated that his protocol evolves as new scientific evidence emerges. For example, he discontinued plasma transfusions after finding no measurable benefit and removed rapamycin from his regimen after reassessing its risk-benefit profile. In 2025, Johnson expanded his mission through the Don’t Die movement, encouraging evidence-based habits that promote healthier aging.
However, Johnson acknowledges that longevity science remains an evolving field, and many of his interventions have not been proven to extend human lifespan. In 2026, he revealed that doctors diagnosed him with autoimmune gastritis, a chronic condition in which the immune system attacks the stomach lining. The diagnosis followed years of unexplained low ferritin levels despite intensive health monitoring. Johnson now manages the condition with regular endoscopies, blood testing, iron treatment, vitamin B12 monitoring, and ongoing medical supervision while continuing to refine Blueprint. Although experts support healthy habits such as exercise, sleep, and nutrition, they caution that no current protocol has been proven to stop or reverse human aging.
Biohacker Bryan Johnson Reveals Chronic Autoimmune Stomach Condition
Bryan Johnson revealed in July 2026 that doctors diagnosed him with autoimmune gastritis (AIG), a chronic autoimmune disease affecting the stomach lining. He announced the diagnosis after years of unexplained low ferritin (iron stores) despite following his strict Blueprint longevity protocol. According to Johnson, specialized blood tests, an upper endoscopy, and stomach biopsies confirmed that his immune system was attacking the acid-producing cells in his stomach. He wrote that “my stomach is eating itself,” describing how the condition had remained undetected despite extensive health monitoring.
Johnson explained that autoimmune gastritis can reduce stomach acid production and impair vitamin B12 and iron absorption, increasing the risk of anemia and other long-term complications. He also revealed that he has managed hypothyroidism since age 21, another autoimmune-related condition. Following the diagnosis, Johnson began iron infusions, vitamin B12 monitoring, regular endoscopies, blood testing, and periodic stomach biopsies under medical supervision. Although autoimmune gastritis has no known cure, Johnson said he plans to use data-driven research and advanced medicine to improve treatment while continuing to refine his Blueprint longevity program.
Bryan Johnson Net Worth (2026) | How did Bryan Johnson get so rich?
Bryan Johnson has an estimated net worth of approximately $400 million to $800 million as of 2026. Although Johnson has not publicly confirmed his exact wealth, most estimates trace his fortune to the $800 million sale of Braintree to PayPal in 2013. Additionally, he has invested heavily in Kernel, OS Fund, and Blueprint, while funding ambitious longevity research with his personal wealth. Johnson has also stated that he spends around $2 million annually on his health and anti-aging program. As of 2026, he remains one of the wealthiest and most influential entrepreneurs in the longevity and biohacking space.
