Ingesting Methylene Blue

Ingesting methylene blue is highly controversial and generally not recommended. Andrew Huberman discussed this topic with Dr. David Sinclair in the context of practices that lack proper scientific backing. Although methylene blue has been found to extend the lifespan of some lower organisms, there is skepticism about its safety for human consumption, primarily due to the significant staining effect it has on the body. Huberman expressed concern about the practice, questioning its logic and suggesting that perhaps those who engage in such activities should be referred to a psychiatrist 1.
