Can I take vitamin C if I am on heart medications?

You should always discuss any vitamins or herbal supplements that you are considering taking with your primary care physician, plus any other specialists you are seeing, including your cardiologist. Many supplements may change the effectiveness of various medications you may be on to manage your heart disease. 

For example, though more research is needed, vitamin C may interfere with the ability of warfarin (Coumadin) to thin your blood. Conversely, it may increase the level of aspirin in your blood.
