According to the Mayo Clinic, supplements such as calcium, iron, multivitamins containing iron, and antacids containing magnesium or aluminum can potentially have interactions with thyroid medications. They should be taken several hours before or after your thyroid medication to avoid an interaction.
Similarly, you may ask, can I take vitamins with levothyroxine?
levothyroxine multivitamin with mineralsYou should separate the administration of levothyroxine and multivitamin with minerals by at least 4 hours. If your doctor does prescribe these medications together, you may need a dose adjustment or special test to safely use both medications.
Similarly, how long after taking thyroid meds can I take vitamins? Whether you take iron alone, or as part of a multivitamin or prenatal vitamin supplement, you should wait at least two hours after taking your thyroid medication.
Beside above, what supplements interfere with thyroid medication?
Yes. Calcium supplements — or antacids containing calcium — can interfere with the absorption of thyroid hormone replacement medications, such as synthetic thyroid hormones levothyroxine (Synthroid, Unithroid, others) and liothyronine (Cytomel), as well as thyroid extract supplements.
What vitamins should not be taken with Synthroid?
Aluminum and magnesium containing antacids, calcium carbonate, simethicone, or sucralfate and iron-containing compounds may decrease the absorption of Synthroid; so you should not take these medications within four hours of taking Synthroid.
