The IADFSA was CREATED BY BIG PHARMA in 1998

My friend, the The International Alliance of Dietary Food Supplement Associations was CREATED BY BIG PHARMA in 1998.  Their original creator and first chairman came from Capsugel, a subsidiary of Pfizer.  Byron Johnson, the chairman quoted in your post came from another industry front group, the Council for Responsible Nutrition, whose members included Bayer, Monsanto, Cargill, and Archer Daniels Midland (think GMO soybeans in a big way), and who is listed on Sourcewatch as a group whose name belies it's true agenda.  They support supplements regulation too.

I would not trust ANYTHING they favored, but instead be looking for the fox in the chicken house.  Simple logic dictates that any recommendation by a group created or controlled by Big Pharma is going to be in the best intereste of Big Pharma, and quite likely not be in the interest of those who make, sell or take anything that would compete with Big Pharma's patented medicines.

I would like to see some kind of proof of health claims myself - but how does one do that without the pervasive influence and control by the trillion dollar industry which benefits by suppressing natural and alternative competition?  They are simply too large and too pervasive - like the sand in the great dustbowl days in Oklahoma.  And it is the poor consumer who reaps those grapes of wrath.
