We are at a place with health comms where they are pointless. Every health influencer is a shill who shrieks about how the doctor is evil 

With that in mind, take whatever overpriced crap you want, including methylene blue. I just beg you to heed this warning https://neurofrontiers.blog/what-methylene-blue-can-and-cant-do-for-the-brain/

“methylene blue has what’s called a hormetic effect. It means that low doses produce beneficial effects, whereas high doses are harmful. In other words, more isn’t always better and sometimes it’s a lot worse.”
