Methylene Blue: Miracle Supplement or Dangerous Hype?
Methylene blue, an old drug, has recently resurfaced as a potential 'miracle supplement,' touted for memory improvement, increased energy, and mood regulation. However, the reality is more nuanced.

Furthermore, methylene blue exhibits a hormetic effect—low doses might be beneficial, while high doses are harmful, potentially causing side effects such as blue urine, bladder irritation, nausea, vomiting, headaches, and even life-threatening complications. Therefore, until further research confirms its safety and efficacy, self-administering methylene blue is strongly discouraged.
