Can I use Medifast if I am currently using thyroid medication?
Individuals with hypothyroidism can use Medifast under the direct supervision of a physician. Your physician may want to monitor your labs and medications, and may suggest using a soy-free Medifast Meal around the time of day that you take thyroid medication. Within four to six weeks of starting the Medifast Program, you’ll want to get your thyroid levels rechecked to help ensure that you are receiving a therapeutic level of medication. For information on soy-free products, please refer to our Allergen/Dietary Information (PDF).
