- Question from Hager: I've recently heard that Vitamin C isn't good for women who have had breast cancer. So much so that my friend's oncologist recommends that she doesn't take it at all. Should I worry about taking it?
- Answers - Gary Deng Vitamin C was used initially for cancer prevention. Several large-scale clinical trials have tested the potential in cancer prevention. Unfortunately, none of those trials showed a benefit. There are people who did laboratory research showing certain cancer cells appeared to require Vitamin C to thrive. Hence the caution that Vitamin C may not be good for cancer patients. My opinion is that a moderate amount of Vitamin C is helpful, but I do not recommend taking excessive amounts of Vitamin C. By "excessive," I mean more than 2 grams per day. At this point, we do not know for sure whether Vitamin C would help or hurt cancer patients, so a moderate amount of Vitamin C intake appears to be the safest way at this point.
