Microplastics, Blood Tests & Daily Detox | Bryan Johnson Podcast

After a series of sauna sessions, Bryan’s toxin panel showed reductions ranging from 15% to 100% across various chemicals. Mike was shocked by the near-zero levels achieved. The team believes sauna likely contributed most of Bryan’s 93% microplastic drop. They want to test sweat for microplastics to confirm this pathway. This protocol is a core part of Bryan’s daily routine and he credits it with pulling his environmental toxin load to extremely low levels despite unavoidable exposures.

Mike explained that TPE is great in theory for removing plasma particles, but the bags and albumin used may reintroduce microplastics. Blood donation avoids that because it’s a one-way removal. He estimated donation volume as 300–500 cc and suggested that repeated donations slowly deplete microplastic levels. Bryan punned about ‘heal yourself and heal the planet’ and joked about organizing ‘blood parties.’

Blueprint tested both lancet types and found the plastic version dramatically skewed the microplastic count. The metal lancet is a requirement for accurate testing, and the test instructions emphasize this. Bryan noted the metal lancet is like a ‘little metal sword’ and can be psychologically difficult to self-administer.
