Dr. Westin Childs Podcast: Thyroid | Weight Loss | Hormones

Over 100 million people will fill a prescription for levothyroxine this year and most of them have no idea how many different things interfere with its function. This includes food, medications, and, yes, even supplements. Which is why I put together a list of supplements that can cause problems with thyroid medication. Are you taking any? 1. Biotin - Biotin interferes with the ACCURACY of thyroid medication and levothyroxine. 2. Caffeine - Caffeine decreases the absorption of your thyroid medication. 3. Iron and calcium - Both iron and calcium bind to and inactivate levothyroxine and other thyroid medications. 4. Glucomannan and other fiber supplements - Glucomannan and fiber supplements delay the absorption of thyroid medication. 5. Estrogen enhancing supplements. - Supplements that increase estrogen increase thyroid binding globulin which decreases how much free thyroid hormone your body can use.
