The rules and laws are different everywhere, and it’s never the same! That’s the real answer! While it would be nice to be able to give a more detailed response the question ‘why are supplements not regulated,’ that’s the truth! In some places they have better regulation than they do elsewhere, and then in other places, they barely have any regulation at all!
It all depends on where you are. Even in some first world countries, not all supplements are as well-regulated as they should be. You’ll have to look into the laws and rules of wherever you are to get a better picture about what the current state is where you are, and why.
