If supplements are unregulated how do I know which are shit?

"The Food and Drug Administration (FDA) does not evaluate the effectiveness, safety, or quality of dietary supplements — or the ingredients in them — before they enter the marketplace"

In my country there are two types of substances: drugs and supplements. Supplements aren't regulated but drugs must be aproved. Some however can fit in the both categories, and some manufacturers submit their products to testing to the ministry of health. So you can buy vitamin A,B,C,D, etc, and other supplements that are labeled as drugs and be sure they are of good quality
Usually big pharma companies like Merck, Bayer, Pfizer, etc. send their products to testing, so their vitamins and minerals are legit(they are more expensive though).

All of them are shit. Unless you are deficient you wont see any benefit from supplements.
