Doctors issue major warning over viral ‘limitless pill’ used by celebrities as “brain fuel” |

Methylene blue, a dye developed in the 19th century, is gaining attention on social media as a purported cognitive enhancer, with influencers and wellness personalities attributing qualities such as improved mental clarity and longevity to it. Doctors and neuroscientists, however, caution that these claims are unsupported by robust human research. Methylene blue does have FDA approval for treating methemoglobinemia, a blood disorder, and is recognized on the World Health Organization’s essential medicines list. Clinical settings utilize it under strict supervision, far removed from how it is being marketed and consumed in the wellness community.

Even though some animal studies have suggested potential cognitive benefits, such as enhanced mitochondrial function, the majority of the research does not yet validate these claims for human use, particularly at non-prescribed doses. Methylene blue can pose risks, including potential interactions with certain antidepressants that may lead to serotonin syndrome. Experts emphasize that self-medication with unregulated products poses real danger.

Health professionals advise caution, urging individuals to consult qualified clinicians if considering methylene blue for cognitive enhancement or other non-approved uses.
