Anyone have experience using a reliable brand of glutathione? I've used tationil by Teopharma (I think that was the way it was spelled) but it's really difficult to get a company to import it from Italy. And there's a lot of fake stuff. There's tons of brands sold out of the Philippines, Thailand, etc but I figure they're all made in China. That would be fine as long as they're real but I have no way of knowing. I used it for its cleansing benefits but many blacks and Asians use it to lighten their skin. If you've used it do you feel it was worth it? Some claim it is their most important supplement for overall health.
