18-year-old, "mocha"-skin-toned, African-American male - thinking about taking 1500mg Glutathione pills. (photos)

I taking them to lighten my skin and for the other known benefits as well. I wanted to know 3 things: 1. How much of that Glutathione - percentage wise - would actually make it to my cells after digestion? 2. About how long would it take me personally to reach a nice, light "caramel" complexion? 3. Is it worth taking orally?
