Biohacker Bryan Johnson reveals shocking reason drinking from glass bottles might be worse for you than plastic

Even though health is subjective, you tend to think of the likes of Robert F. Kennedy Jr. when it comes to the 'healthiest' people in the world.

Giving the Secretary of Health and Human Services a run for his money, you might remember Bryan Johnson as the biohacker who's trying to live forever.

Although sometimes controversial for his methods that includes measuring his son's erection data and injecting his plasma, Johnson is also known as that guy who took an 'epic dose' of magic mushrooms on a livestream.

While some remain unconvinced by Bryan Johnson's work and the fact that he apparently spends around $2 million a year on his Project Blueprint anti-aging regime, others hang on his every word.

Even though we're not all sold on his lunchtime menu or the fact that he takes his last meal at 11:00 a.m., he's offered a warning that means you might want to think twice about how you consume your drinks.

We've all heard about the perils of microplastics and what they're doing to our bodies, meaning some avoid plastic containers and cutlery altogether.

Speaking to the Full Send Podcast, Johnson warned that drinking from glass bottles could arguably be even worse for our health.

Making a seemingly out-there claim, Johnson maintained: "Glass water bottles have more microplastics than plastic water bottles."

Saying that he's looked at the data, the biohacker reiterated: "The microplastics don't come from the glass, they come from the lid. It's the paint that goes on the lid, and it chips off."

Referring to drinking from glass bottles instead of plastic as 'counterintuitive', Johnson continued: "This is why testing is always the best thing to do on all things. It's very dangerous to have assumptions."

Asked how he drinks his water, Johnson said that he has an in-house reverse osmosis water system, which pushes water through a semi-permeable membrane and is said to remove up to 99% of contaminants. This includes bacteria, fluoride, heavy metals, and salts.

He says that he tried to find somewhere with a reverse osmosis system when he's out and about, but if not, he says he simply does his 'best' to avoid contaminants.

There's an increased discussion about microplastics, especially after they were found in semen for the first time. A 2024 study published in Environmental Science & Technology said that microplastic consumption has increased sixfold since 1990, especially in global hotspots like the USA and China.

Responding to Johnson's musings, opinions were split as some claimed he was quoting misleading studies. Flying the flag for glass, one person wrote: "Nope. Just a small plastic lid liner with #13 plastic. I’ll take that over plastic bottles. Tastes amazing too."

Another joked: "My great grandfather lived off whiskey and cigarettes and made it to 97 and was one of the smartest men I’ve ever met. Let’s see how someone like Brian does. I’m very curious."

Highlighting the dangers of microplastics, someone else said: "It’s simply a manufacturing problem looking for a solution. A zero plastics glass bottle process is begging for creation."

A fourth warned: "The most plastic residue is the receipt paper everyone rubs all over their fingers right before they eat. Folks, let them throw the receipt in the trash or go wash your hands before you eat. Do not touch the receipt or put it in your pocket."

Either way, you'll probably want to avoid putting any kind of unnecessary plastic into your bodies.
