Here's the real truth behind all this: we really don't know a whole lot about gut flora, there is no single baseline true diet that everyone should follow because our needs and our organisms all work in subtle different ways, a deficiency in vitamins or nutrients is not a hardline thing and may come in levels, and tests we currently have don't show everything nor gives a clear picture of what people should use to supplement deviations. Take it from someone who went through a few different licensed doctors specialized in nutricion. It's an extremely complex area of science. You should think about it less like mechanical engineering, and more like weather prediction. Doctors will take some variables and try to come up with solutions based on it. The more specific your needs are, the more intrusive and invasive treatment and diagnostics will become, and the more expensive it'll be because it needs to be individualized to the highest degree. People should also know that not every condition, deficiency and other stuff can be controlled with diet changes alone. There are some stuff that is far more influenced by your genes, for instance. This is the main reason why celebrity crap won't work for anyone. If you don't have the organism of a specific celebrity, you won't get the same results by just using the stuff they claim to be using - when that's even true I mean, for the most part it's all bullshit. With that in mind, you should of course still be wary of snake oil crap and advertisement that promises to solve all your problems. They most likely won't. Because organisms are extremely complex borderline chaotic environments with tons of unpredictable variables, so there's no way to guarantee stuff with generic chemicals. But really, science isn't as clear cut as saying stuff like multivitamins won't help anyone, just as much as it isn't as clear cut as saying it will. There are of course lots of studies around, ranging from good ones with good application of scientific method, all the way to obviously skewed ones financed by interested parties to make it look like their products are needed in some way. The better way to approach this is to be aware of scammers, avoid crap that promises you an unrealistic solution as long as you pay for it, keep a diversified diet, and an awareness of what seems to work for you and what doesn't. And this should be obvious to anyone, but following the recommendations of someone without a direct financial interest and that has studied nutrition for years is a far better option that listening to ignorant idiots spewing crap out of their mouths based on annedoctal evidence who are trying to sell you expensive crap. This is just critical reasoning.
