The first step in your journey to feeling better is to talk with your doctor. It is important that you accurately describe your symptoms and provide complete detail about your other medical conditions, other medications or supplements that you take, (both prescription and non-prescription) and your diet. Many patients don’t tell their doctors about the nutritional supplements that they take, but as you’ll discover, even the most common dietary items problems for your thyroid medication can make your treatment less effective.

The following tools have been created to help you to give your doctor the information that he/she will need to determine the right hypothyroidism treatment for you:5

Nutritional supplements such as iron (for treating anemia) or calcium (for preventing bone less) are also known to affect levothyroxine.
