Detox isn't complete bullshit. I was in treatment for a pretty bad disease a couple of years ago, and as the bacteria was being killed off, several MDs (legit medical doctors) told me how important it was to detox and flush that shit out of my system. But you're right that you don't need fancy powders and such. Drinking tons of water, especially lemon water, works the best. There were also a couple of supplements that were recommended that helped. Widely available supplements, not pyramid scheme stuff. Many doctors, including the infectious disease specialist and gastroenterologist, also strongly recommended eliminating gluten and dairy. I don't have any allergies, but both said A LOT of people have slight intolerance. And eliminating them will only boost the immune system.My gastro also went on about how gluten, like sugar, really has no health benefits at all anyway.
