How effective is methane blue

Methylene blue has several applications and effects that have been discussed on the Huberman Lab. Dr. Craig Koniver mentions that it is absorbed well orally and has been used as a cognitive stimulant, potentially improving brain function such as recall and memory 1. It operates by enhancing mitochondrial efficiency, which could also make it effective as an antiviral agent and aid in conditions like carbon monoxide poisoning by boosting oxygen uptake in blood cells 2 3.

However, its use isn't without quirks, such as turning your urine green or blue, and it can stain your mouth if taken in large doses or liquid form 1 3. Despite being available over-the-counter as a supplement, methylene blue is historically a prescription drug 3.

There is skepticism about the broader health claims made for methylene blue, like its purported effects on lifespan extension, which are based on studies in lower organisms rather than humans 4. Users should exercise caution and seek medical advice before using it, especially given its roots as a fish tank cleaner.
