1/ My results offer a new sense of hope for the detoxification of microplastics from the testis and semen, especially after the concerns raised by a study last year. To our knowledge, this is the first report of any correlation (especially over two timepoints) between blood and

2/ Similar correlations have been observed for plastic leachables, but never for microplastics, and never longitudinally over time with effective mitigation interventions. Earlier studies showed correlations between serum, blood, and urine for some plastic leachables, including

3/ Microplastics in the testis and semen can disrupt sperm motility, hormones and fertility markers, the good news this seems all reversible based on my results. A 2024 study from China, involving 113 participants, corroborated these findings, detecting microplastics in all

* a reverse osmosis water system is good to filter out microplastics. Sorry for botching that sentence.

@bryan_johnson How do they leave your system?

@Jason it's a good question and we don't know

@bryan_johnson "I don't worry about microplastics and I feel fine!"

@AutismCapital plastic man to the rescue!

@bryan_johnson every day Brian Johnson says a brand new sentence 😂

@taco_eth I think you are correct, this sentence has never been spoken before

@bryan_johnson What RO do you use and how do you add minerals back in?

@Baze_Trader below is what the company says it does. I test the water monthly and it performs to spec: "This nine-stage reverse-osmosis system progressively purifies and “polishes” tap water. A sediment filter first strains out large particles, followed by a carbon block that removes

@bryan_johnson Reverse osmosis is a positive or negative for microplastic reduction?

@WealthyDetecti1 Reverse osmosis is a positive for microplastic reduction

@bryan_johnson A reverse osmosis water system is a big no-no?

@bryan_johnson How can the effects be measured as their is no control group? Everyone has microplastics in their bodies right?

@bryan_johnson The way you worded it, having an RO system is a no-no? “I also avoid the big no-no’s like microwaving in plastic, plastic cutting board, and having a reverse osmosis water system.”

@bryan_johnson Why not edit your original post to make it clear that “having a reverse osmosis water system” is *not* is “big no-no”? Stating that you botched that sentence is clearly not corrective enough (based on the replies).

@bryan_johnson Wait, Reverse Osmosis systems are potentially adding microplastics?! I have been happy and proud of my system for years, drinking far more water than I would have normally. What would you recommend I do for my fresh water?

@bryan_johnson Bro just casually boasting about his nut being more pure than yours

@bryan_johnson Only way to prove it for real is to let me do a taste test

@bryan_johnson 5% chance my feed will open with something about @bryan_johnson's bodily fluids

@bryan_johnson Fascinating, thanks for sharing! I wonder if hot yoga has similar effects

@bryan_johnson Continual testing will age you faster though!!!

@bryan_johnson Interesting. Any measurable change in Testosterone levels?

@bryan_johnson Avoid plastic dental floss. Glide type floss is made from same fluoropolymers as non-stick pans. You'll absorb microplastics + forever chemicals. Gums, cheeks & under tongue are highly vascular + semi-permeable. I've switched to natural silk floss

@bryan_johnson Does this mean that taints will stop shrinking? A better question is did Bryan measure his before and after the removal of micro plastics? @joerogan we need answers
