Thanks Sage. I am thinking about just leaving the vitamin C out and doing a pretest with nothing and a posttest with NCD. The reality is I am so sensitive that the more vitamins I take, the worse I often feel because I develop a sensitivity reaction to them. If I am able to get myself on the NCD, I don't know if I will tolerate vitamin C or any other vitamins for that matter. I think I'd rather try one thing at a time. And since my dentist did not mention vitamin C (only the NCD test website), that's what I think I will do.

Thanks again. Good luck when you try the test next month! Keep me posted on your progress.
