Biohacker spending $2,000,000 a year to ‘live forever’ claims common daily habit could be 'lowering IQ'

Bryan Johnson has alleged that a daily habit that most Americans do could be affecting their IQ.

Johnson is a 47-year-old biohacker and venture capitalist who spends an eye-watering $2,000,000 annually on reversing the aging process.

From getting a 'total plasma exchange' to having his joints injected with hundreds of stem cells – there's very little that Johnson won't do in a bid to make himself younger.

In fact, last year he insisted that because he's managed to successfully slow down the aging process, he can celebrate his birthday once every 19 months instead of 12.

Johnson has looked into almost everything when it comes to things that positively and negatively benefit the body, and he's now claimed that a daily habit of most Americans' could be allegedly lowering their IQ.

The habit is question is drinking water; something we should be drinking around 2.7 liters or 3.7 liters a day (depending on your gender), says Mayo Clinic.

In a lot of water supplies globally, it's likely you'll find fluoride in it – which may be there naturally or added through fluoridation schemes.

In America, water has had fluoride in it for decades, but Robert F Kennedy Junior, the newly-elected Secretary of Health and Human Services who often goes by RFK, wants to remove it.

As to what it is, fluoride is a mineral that occurs naturally in water, soil and air.

It's been demonstrated to prevent dental cavities, explains Reuters, has been added to American water since the 1900s. The Michigan city of Grand Rapids being the first place to add fluoride to its water supply in 1945, and now, around 63 percent of Americans have fluoride in their community water systems, the CDC said in 2022.

But some studies have suggested that higher amounts of fluoride in water may lower a person's IQ, which Johnson has also alleged.

Speaking to Mail Online, the biohacker shared: "My team and I have been looking at RFK's proposals and we've been checking them against the scientific literature, and fluoride was one that actually stood up to the evidence.

"It seems to be an evidence-based decision to remove fluoride. It's a good decision to remove it from the water supply."

While the likes of Johnson and RFK have their questions about fluoride-infused water in the US, it's been suggested elsewhere that the doses of fluoride used in most water supplies doesn't pose much risk.

In a episode of Johns Hopkins University's podcast Public Health On Call, Charlotte Lewis, MD, a paediatrician at Seattle Children’s hospital and a professor at University of Washington Medicine, said of the idea of scrapping fluoride from water: "Trying to connect fluoride in the water to health risks has been going on for decades. Those potential connections, for example, hip fractures or bone cancer, have all been disproven through robust research."

Lewis continued: "The more recent concerns that have arisen, are about the impact on neurocognitive development based on fetal and early childhood exposure to fluoride.

"We don't know what the exact dose is that would cause those problems. We know that in environments, such as India, China, and Iran, where there's very high concentrations of fluoride naturally present in the soil, that there can be an increased risk of a neurocognitive effect of very high exposure [to] fluoride—but the quality of the studies is poor.

"Based on that, concerns then spread to lower levels of fluoride exposure, including what we use for community water fluoridation."
