The banning of vitamin/supplements

Does anyone know if the FDA or any other national governments has been able to totally ban a supplement from the public? I keep reading Google rumors of this for certain vitamins. these are actually kind of old articles so I guess the ban was reversed because you can still buy P5P on the internet. Will someone of the forum alert everyone when this becomes a reality so we will know when to stock up?
Thanks, Emily

this is a long history, FED's in USA are assalting farms where people sell milk like suspets of terrorism (i think exists videos in YT). but the dementia is far deeper. I read some years ago a test on cod liver supplements and many are near useless, so not only you need to know what suplement is good for you, also the brand.
