Bryan Johnson, the 48-year-old tech entrepreneur turned longevity pioneer, has made headlines with his latest achievement: an 87% reduction in microplastics found in his s**en. During his appearance on the Full Send Podcast, Johnson provided insights into this groundbreaking personal experiment and its implications for human health.
Johnson didn’t mince words when discussing the prevalence of microplastics in the human body. “Microplastics are a major problem. We all consume a lot of microplastics. Microplastics is stored in the brain, in all the organs, and your blood,” he explained to the podcast hosts.
The entrepreneur revealed that his team conducted what he described as “a first ever experiment. Nobody in the world had ever tested microplastics in blood and s**en.”
While previous studies had examined microplastics in s**en, Johnson’s approach was unique. “People there was a few studies where people tested microplastics in s**en. Every single sample had microplastics,” he noted, emphasizing the universal nature of this contamination.
Johnson’s success in reducing his microplastic levels came through a comprehensive protocol that he developed with his research team. “When I started doing this protocol, my microplastics in my ejaculate lowered by 87%,” he stated matter-of-factly.
He emphasized the significance of this achievement: “Our success was first in world demonstration to lower microplastics in the s**en and blood at the same time.” This dual reduction represents a major milestone in understanding how to combat microplastic accumulation in the human body.
When asked about the importance of reducing microplastics, Johnson was clear about the health implications. “You don’t want to have microplastics in your s**en. It’s not good,” he said, adding that maintaining optimal fertility markers is important regardless of whether someone plans to have children. “No matter your situation there’s hope,” he offered, suggesting that these findings could benefit anyone concerned about microplastic exposure.
Johnson’s microplastics research is part of a larger $5 million investment in longevity science, with most of that money allocated “towards researchers and scientists who do all the research.” His team of approximately five people focuses on identifying what works through rigorous measurement and testing.
“Our key thing is we measure everything,” Johnson explained. “People like there up until now like no one’s measured microplastics in their ejaculate. Who’s doing that? You know like there was a study on city but like it’s not a common thing. So we just do uncommon measurements which allow us to have uncommon insights.”
While Johnson didn’t detail every aspect of his microplastics reduction protocol during the podcast, he did offer some general guidance on minimizing toxic exposure. He mentioned avoiding certain materials and being mindful of everyday items, from toilet paper to water bottles.
Regarding water consumption, he shared an interesting finding: “Glass water bottles have more microplastics than plastic water bottles.” He explained this counterintuitive result: “The microplastics don’t come from the glass. They come from the lid and it’s the paint that goes in the lid and then it chips off.”
At home, Johnson uses “a reverse osmosis water system” and when traveling, his team packs water or seeks out locations with similar filtration systems.
Johnson’s microplastics research fits into his broader mission of achieving what he calls “longevity escape velocity” by 2039, where one year of chronological time passes without biological aging.
