I suggest them since I believe they helped me. I could be wrong. I do a lot of other things like drinking a tablespoon of Bragg Apple Cider Vinegar with every meal, taking
Chlorella, raw honey, probiotics, milk thistle/dandelion root (detox/liver), and cayenne. I also take a bunch of other stuff if certain problems arise, so I have a large stock of different things for different issues. I think one of the biggest things you can do is cutting out wheat completely out of the diet, and it can help anyone with their health immensely if they do this, and eliminate a LOT of weight (I still make/eat pizza, bread, noodles, soy sauce, and so forth without wheat, and it tastes just as good if not better.)
With this alternative medicine stuff there is no true "authority". You literally have to try it yourself and try to be as objective as possible. Vitamins/supplements/detox/elimination diets can take up to 4 months (usually less) before they start working, so you have to be patient. The most important part is being objective. I literally have to believe it wont work on purpose so I don't fall into the placebo effect like many people do. I've tested many vitamins/supplements on myself and some work, some don't (for me at least.) Part of this journey is figuring it out on your own.
Following a consensus isn't always a good path, since if you did, you wouldn't be following alternative medicine in the first place.
