Question: How do I know if a vitamin, supplement, or herb will interact with any drugs that I may also be taking?
Answer: So the question is, can there be an interaction between my vitamins, my herbs, my supplements, and prescription medicine. And the answer is absolutely yes. It is very important when you see your physician to have a list of the vitamins, the supplements, the herbs that you are taking, even if your physician does not ask the question, are you taking a vitamin, supplement, or herb, feel free to offer your physician this answer. We know for certain that there are many supplements that can affect prescription medication, raising the dose or lowering the dose of the medication. There are many resources for finding out about herb drug interactions, supplement drug interactions, but these are no substitutes for talking to your health care provider.
