They appear to be curing mankind of every conceivable disease out there with their products. I wonder how they get away with so many claims?
"Dietary supplements" and "nutraceuticals" are kind of like cosmetics. You can talk about "clinical tests" that aren't really like clinical trials, you can make up names for ingredients, you can create meaningless "statistics", and you'll be fine as long as you don't claim whatever it is cures cancer. Or literally makes your skin younger. That's why cosmetic ads carefully say you'll enjoy "the appearance of younger skin".
