Because they don't want some jerk off like you selling a supplement and claiming it can prevent cancer. Yes you quoted exactly what they are saying, but you are grossly misinterpreting what it means. Also the FDA doesn't make the fucking law, go back to civics class.
No they didn't, they stated what they legally have to to comply with the law.
Again, no they aren't, they are complying with the law.
Yes.
It's not an assumption. We know it is safe, that is why they put it in vaccines.

From the FDA website:
So there you go, it's not some crazy conspiracy and it's not because the FDA want to be assholes and hate supplements. Unless of course I can't trust any information that comes from the gubment or the fda, which brings me to my next point...
Why is the FDA a credible source for evidence when you think it supports your point, but it's not credible when it supports the real point? You have repeatedly used the FDA as a source of information, as does many of the articles you keep posting. The minute I post anything from the FDA or that used the FDA as it's original source you immediately start chanting about "big pharma" and say they can't be trusted.
I feel like no amount of evidence is going to convince you. No matter how many sources get debunked, no matter how many times a flaw in logic gets pointed out, and no matter how many times you are shown that evidence you think is supporting your point is really just a smaller part of a complete picture that really supports the opposite of your point, you still won't change your mind. You say that you are logical and concerned only with the evidence, but you demonstrate otherwise with every post you make.
I will still address your specific questions about mercury, MSG, and aluminum at a later time. I will need to check it out and compile my sources.
You do realize that the FDA is controlled by the government, right? And that the government makes the law? So you're saying it's illegal to claim that supplements can cure, treat, or prevent disease (even though it's been proven that lots can), because they're looking out for the safety of the public? They are subtly telling the public that there is nothing they can do about their conditions unless they take their drugs. It's illegal because if people knew they could cure or treat their issues by simply buying supplements and other health products that actually work and don't have side effects, they lose millions of dollars. Newsflash, the FDA doesn't approve dietary supplements because they cannot profit off them. The FDA, however, approves their own creations and you blindly believe them. I truly feel sorry for you when you tell me that you trust the FDA. http://www.anh-usa.org/vaccine-mania/
