After seeing a million ads for this I broke down and tried it. First of all, the taste. It's not good. Secondly, it's expensive ($100 for 30 days?). And third, I just don't see the point. Like everything else in the supplement industry, it's doesn't have to go through FDA approval, and with that comes a whole host of concerns. I have a bit of a gripe (literally have a whole blog on it, oops) with products that don't cite their sources, especially when they have claims like "boosts immunity" or "supports" digestion. With AG, the evidence doesn't seem to be there, and I'm not sure what benefit it confers that throwing some spinach in a smoothie wouldn't also do for a literal fraction of the price. Not impressed.
