Methylene Blue: The Brain-Boosting Chemical?
Methylene blue, a synthetic dye with historical medical applications, is being promoted online as a nootropic to enhance cognitive function, but current evidence supporting its benefits is limited and mostly from animal studies. While it has some medical uses like treating certain blood disorders and protecting mitochondria, its safety profile includes serious risks such as interactions with medications and potential harm during pregnancy. Larger, more comprehensive studies are needed to confirm its efficacy and safety for brain health.
