There's a huge difference between the terms "alternative" and "adjunctive" as, by now, you've been educated. Your oncologist and dietician should be able to help you with adjunctive Tx. Most of the literature I have read does not recommend vitamins and/or herbal stuff during treatment. The most important thing during Tx is to stay well hydrated and take in enough calories to facilitate healing. I wouldn't recommend taking anything other than what the doctor tells you is ok, even "over the counter" meds.
