Question
Hypothyroidism: Can calcium supplements interfere with treatment?
Can calcium supplements interfere with hypothyroidism treatment?
Answer
from Todd B. Nippoldt, M.D.
Yes. Calcium supplements can interfere with your body's absorption of levothyroxine (Levothroid, Synthroid, others), a synthetic thyroid hormone. But this problem primarily occurs when you take calcium supplements and levothyroxine at or near the same time. To avoid an interaction, take calcium supplements at least four hours before or after you take levothyroxine.
