Given all the fearmongering about toxic fumes, chemicals, microplastics, vapes, and trans fats we're getting pumped into our bodies (before we get to fillers and so-called 'skinny jabs'), it's amazing we're still able to function in 2025.
Feeling a bit like when tobacco companies used to advertize smoking as 'healthy' back in the '30s and '50s, we dread to think what science will reveal in the future about all the toxins we're currently consuming – whether intentional or not.
One major concern for many is the consumption of microplastics, and whether you like it or not, those tiny bits of plastic are currently whirling around our bodies and potentially doing some serious damage.
While there's plenty of advice out there on how to try and limit the number of microplastics we're inadvertently munching in our food, biohacker Bryan Johnson is back with another supposedly revolutionary way to cut back on microplastics.

Honoring himself as the man who wants to live 'forever', Johnson is more commonly known as the man who measured his son's erections, injected his son's plasma, and supposedly de-aged his penis. Johnson's methods are nothing if not controversial, notably as he stopped taking his own longevity drug.
Why are microplastics bad for you?
Still, with microplastics being smaller than a grain of sand and almost impossible to avoid while also being linked to side effects like cell damage and respiratory issues, we'd like to know how Johnson has supposedly removed 85% of them from his body.
As you might've noticed, there's something of an adult theme with many of Johnson's experiments, and this time, he's explained on X how he's removed 85% of microplastics from his ejaculate in just a year.
In November 2024, Johnson supposedly had 165 particles of microplastics in every milliliter of ejaculate, but in July 2025, he's shrunk it to just 20 particles per milliliter. More than just 'pumping' out ejaculate, Johnson says he noticed a 'significant' drop in the levels of microplastics in his blood.
Dipping from 70 particles per ml of blood in October 2024, he now maintains it's down to just 10 per ml in May 2025.
Warning us about why microplastics are such a cause for concern, Johnson reiterated: "Important as a meta-analysis of 36 studies reveals that microplastics induce oxidative stress in the male reproductive system, leading to testicular inflammation, cell death, and reduced testosterone levels, sperm production, and motility.
"Two studies last year showed that microplastics were detected in every human testicular and semen samples tested."
How did Bryan Johnson remove microplastics from his body?
For those worrying they'll have to sign up for one of Johnson's fancy diet plans or shovel a load of supplements into their body, there's good news. The biohacker simply had a 20-minute sauna every day and literally sweated out his microplastics.
While this was the main method of Johnson's hypothesis, he also said he stopped using microwavable containers and plastic cutting boards, which have unsurprisingly been blamed for putting excess microplastics in our systems.
Finally, he splashed $600 on a reverse osmosis water system that uses a high-pressure pump to filter water through a barrier of tiny pores. Then again, with even toilet paper said to put microplastics in our bodies, it appears there's not much we can do to completely stop this worrying trend from infiltrating our lives.
