What do the soldiers of the Second World War, the aquarium fish and the millionaires of technology have in common? A blue liquid that promises a more acute mind, a slower aging and, every now and then, some unexpected in the bathroom. Discover the blue of methylene: a secular medicine that is experiencing a spectacular rebirth.
If in 1876 someone had told the chemist Heinrich dear that his new blue dye would have been successful among the biohackers within 150 years, he would probably have asked him for help. But the blue of methylene, initially intended only for the tincture of the fabrics, soon found application in the medical field: already in 1891 Paul Ehrlich used it to treat malaria, giving this molecule a place of honor as the first synthetic drug in the history of medicine.
@healthsupplements03 Did you know that methylene blue can increase brain performance? 🧠⚡ This powerful compound improves mitochondrial function, increasing energy production and improving cognitive performance! #joeroganshorts #garybreckaclips #Cognitive Health # 1TP2INTAGRATORS UOTROPIC
During the Second World War, the soldiers hired him to protect themselves from malaria, even if with a little less enthusiasm when they discovered that blue was not only the color of the liquid, but also of their urine. Since then, the blue coloring has found use in many areas: from care for rare blood diseases, to help in cyanide’s poisoning, to use as a coloring for microscopy and even as a reliable antifungal agent in aquariums. Yes, probably your fish “used” before you.
Mitochondrial doping? Yes please!
On a chemical level, the blue of methylene is a master in the Redox tricks: he goes from a blue oxidized shape to a reduced color color, becoming a real transporter of electrons inside our cells. This supports the functioning of the mitochondria, the cellular power plants, without which energy would exist only on the electric bill.
In addition, it acts as an antioxidant, reduces oxidative stress, protects nerve cells and inhibits the enzyme Mao, leading to higher levels of serotonin, dopamine and other “happy” neurotransmitters. The result? Best mood, more concentration and – at least in theory – less search for keys around the apartment.

“Smurfs for adults”: cognitive effects and promises of longevity
In a 2016 study, the participants improved their performance in memory tests just an hour after taking a low dose of methylene blue. Other studies have confirmed the positive effects on long -term memory and cognitive abilities in patients with Alzheimer’s disease. The neuroscientists are already assuming: are we on the threshold of a new era of “anti-aging” therapy for the brain?
If you should believe some studies (and biohackers with an unusually blue tongue), blue not only improves brain functions, but also protects from aging of the skin, stimulates the production of collagen and helps to heal wounds. Not bad for a molecule that once adorned jeans.
The elite Blu: da Bryan Johnson a Mel Gibson
Methilene blue is not only found in tubes and medical reports: it is also present on Instagram and Tiktok. Gary Brecka, a renowned biohacker and self -proclaimed human biologist, claims that it is a “mine of benefits for cognition and longevity”. Bryan Johnson, a millionaire who aims to bring his body back to that of an eighteen year old, is already inserting him in his hyper-control regime. Also Dave Asprey, the father of “biohacking”, has been practicing him for almost two decades.
A particularly iconic moment? The video in which RFK Jr. drinks a mysterious blue liquid: result: over 20 million views and the beginning of a new metropolitan legend. Apparently, to join the “blue club”, just dye the language for a few hours and be photographed.
But … is all the one who shines?
Not exactly. Although methylene blue is generally safe at low doses, it is not risks. In high doses it can cause headache, nausea, confusion and even the opposite effect: oxidative stress. Particular caution is recommended in case of concomitant intake of antidepressants, since it can cause a dangerous serotonergic syndrome, accompanied by hallucinations, fever and muscle cramps, much less fun than a video on Tiktok.
Visual side effects are also not negligible: blue urine, bluish sclera, blue spots on clothes and an unusually colorful toilet. A romantic dinner with a new crush after a “biohacker territory”? Better to jump it.
The experts then warn: do not do the wise scientists without the supervision of a doctor. And never use the industrial version for aquariums, unless you want to add an extra dose of heavy metals to your dinner.
A blue future?
Methilene blue is one of those fascinating substances that combines history, science and pop culture. As an instrument in the fight against malaria to fashionless nootropic, today it is a symbol of the search for eternal clarity and vitality. Although there are prospects – from greater ATP production to dementia protection – science has not yet pronounced its last word.
But as with all trends in the world of well -being: carefully, awareness and with a little healthy distance. Perhaps the blue of methylene is truly the molecule of the future. Or maybe just another colorful stop on the road towards the next miracle that promises to make us live longer, better … and with a wise language.
