Heeeheheh.. Wanting FDA approval's a whole other kettle of fish and can of worms! Potassium bromate is FDA approved for use in bleaching flour, glyphosate is EPA approved and levels of it in food FDA approved. Partially hydrogenated vegtable oils and Aspartame are still FDA-Okay..
FDA standards may be a bit too low for being a good standard to hold. They cover some details okay..
However, you might want to know why JCrows doesn't have 'FDA approved' on their products- money, and jurisdiction. The majority of supplements fall under the rules provided for foods, not for medicines. That's the reason for strict rules of information permitted on sites on on products, 'not intended to cure or treat any disease'.
In other words, the cost of approval's a bitch, there's large drug companies in direct competition, and if you consider the widespread ignorance of it's historical medicinal value ( https://en.wikipedia.org/wiki/Iodine#Historical_medical_applications) among folk trained in the common medical field (which is the pharmaceutical company's food and bread), then you've got a clearer picture. A nurse or a doc learning to use Iodine on themselves or their patients would get just as nervous as one of us about the side effects as they see dieoff, de-bromination and de-floridation for the first time.
It can be kinda freaky!
M'glad for the kind of guidance I can get here.. and gonna have some fun with the starch tests..
