Low Dose Methylene Blue

Anyone here have any experiences taking low dose methylene blue for longevity?

I have used it. I was initially reluctant because it just seems so out there. I don’t use it often or much but everything I read seems to endorse it. I took it today but only 2 drops in a half glass of water. My interest is in prevention of Alzheimer’s. I also do Red LIght Therapy and it seems that the combination of Methylene Blue and Red Light exposure (head and face) is beneficial for the brain. I haven’t experienced any side effects. I drink it from a straw to try to bypass my teeth as much as possible as it can stain teeth.

I have taken Meth Blue on and off for the past 2 years or so. Up to 20 drops in small amount of water weeks at a time with some powdered vitamin C that’s supposed to contribute to its power (per the popular book). I experienced no ill effects, but at the same time, no discernible positive effects. I think it’s a question of blind faith in hoping it will pay off in the end.
