Do you take any supplements?

I've been a lab technologist for many years and have done thousands of tests on people. I don't know of any what so ever herbs or natural means that would work other then three good balanced meals a day. I know a woman that worked two jobs and thought that taking 15 vitamins a day and skipping meals she'd be O.K. Several months later she called and said how ill she was. She barely made it to the hospital, her kidneys were in **** down do to overloading on these herbs and not eating properly. It just doesn't work. You need three good meals a day. A doctor can give you tests like I just had. All my final blood platforms, all of them, come out perfect, now, pray tell, why would I want to spend good money on vitamins and other herbs if I am O.K.?
