Fascism in action: big pharma gets the DoJ to go after supplement manufacturers. Now you may say this is about excessive claims but they've been trying for decades to steal the supplement market all to them selves with pull-the-ladder-up regulations and laws. They want you to use their Brave New World drugs instead. The ones with pages of warnings.
To be clear I've spoken with supplement manufacturers who would like some regulation. They want it for assurance that the materials they are getting for their products are genuine. What they don't want is regulations that can only be followed by the large pharmaceutical companies who can only afford the testing. Those are called "pull the ladder up" laws. http://www.reuters.com/article/2015/11/17/us-doj-investigation-dietarysupplements-idUSKCN0T628320151117
