Can I take vitamins, minerals, dietary supplements, or herbs while I get chemotherapy?

Some of these products can change how chemotherapy works. For this reason, it is important to tell your doctor or nurse about all the vitamins, minerals, dietary supplements, and herbs that you take before you start chemotherapy. During chemotherapy, talk with your doctor before you take any of these products.
Combinations of various herbs and minerals can actually block the effect of the Chemo. Large doses of Beta-blockers can hinder the way chemo is being absorbed by your cells. Types of Chemo which attaches to protein molecules that are to be absorbed by the cancer cell are blocked by high levels of the anti-oxidants.
This is why, it is extremely important to discuss with your doctor all consumed supplemental products before and during chemo therapy.
