No matter what kind of cancer treatment you are getting, talk with your doctor before taking any new dietary supplement . If you have been taking supplements and want to keep taking them, it’s important that your doctor knows this, too.
Gather as much information as you can on the dietary supplement you are thinking about using. Then, talk with your cancer care team about it. Ask for their professional opinion as to whether taking the supplement is safe and medically sound. Also ask how it might be safely used along with your cancer treatment.
When talking to members of your cancer care team about using supplements, ask them:
Remember to make sure that your doctors know about all other medicines, vitamins, and supplements you’re already taking, as well. Some supplements can interact with your cancer treatment. For example, antioxidant supplements, such as vitamins C and E, might reduce the effectiveness of some chemotherapy or radiation treatments.
