I also take alot of supplements, regardless of what Dr. Gupta says. I would rather be safe, than sorry there. However, it's good to know the max levels of some supplements so you are not taking too much. There are some good websites at the back of the book that can give you more information.
I drink at least one cup of green tea a day. As far as Perricone, I use some of the face products, but not the supplements.
What I need to work on is my ATTITUDE!! It helps to surround yourself with people who naturally lift you up and stay away from the downers!
