Avoid minerals: Levothyroxine interacts with minerals such as iron, calcium, and magnesium, which lower the activity of thyroid medicine. Many antacids contain magnesium and aluminum, so avoid taking them when you're on the thyroid supplement levothyroxine. If you take iron-containing products such as multivitamins with iron, make sure you do so at least two hours before or after you take your thyroid medication.
