FDA amongst others. Rigorous testing from what Ive been able to find. Its manufactured by an Amway subsidiary called Access Business Services or some such misnomer, sounding more like an offering for shared office space than vitamins & weight loss supplements huh?. Where its made I dont know, but as you'll likely be handed a free sample next time you hit the Joe, origin of manufacturing must be stated on the label..... as for the rest of your post, thats my fear. A captive audience of emotional & excited bodies to sell to; the NHL & the Red Wings some pretty decent bait. Kids programs with Mom or Dad or both in tow; Amway IOB's planted throughout the building; creeps me out too, just thinking of the possibilities, a MLM's wet dream.....
The FDA regulates a couple of things. A lot of it is about what you claim on the label. Ethical pharmaceuticals are only approved for a given indication after years of clinical research is submitted to support the claim, along with the appropriate toxicity, carcinogenic, and other studies. You cannot say X is indicated for disease/condition until you present the data that shows it works and exactly how. Manufacturing conditions are monitored under GMP guidelines, which depend a lot on what is being ingested or injected into the human body (tablets, shots, infusions, creams, drops.... my list isn't meant to be exhaustive).
The nutritional and supplements guys operate under a different set of rules. The manufacturer has to abide by the requisite manufacturing practices (see how some Pharma companies are having problems with offshore facilities). You can make Vitamin D and slap on a sticker that says, Vitamin D. That's it. You don't have to claim that it really will cure anything or that people with certain conditions should take it.
Amway is a marketing company. They don't have the expertise to make this stuff but these guys do:

A Holland, Michigan, company. For example.
So you just slap your sticker on it and see how many people will buy into your "added value" schtick. Imho.
Just eat berries of various colors, some fish oil, and brightly colored veggies instead.
