I really wonder about all this Dr. Oz stuff, I'm thinking maybe it's a mixture of things he actually promotes that are not so good and things that just throw his name on them, i can't believe he promotes all those things you see in ads.
I don't believe in any supplements, they may work temporarily but who knows what you're doing to your body. You can do it without,maybe slower,but if you end up living longer...isn't it worth that?!
best of luck
