How to diet with liothyronine

Updated November 21, 2016

Maintaining a healthy diet while on liothyronine, a thyroid medication, is the best way to contribute to your overall health and well-being. Liothyronine is a synthetic hormone that is typically prescribed for people who are hypothyroid: they do not produce enough thyroid hormones. Low thyroid levels can cause a variety of symptoms like weight gain, tiredness, hair loss, and lack of energy. This medication, along with a healthy diet, can reverse some or all of these symptoms.

Talk with your doctor about any medications or vitamins you are taking, as well as any dietary restrictions or changes that could potentially interact with this medication. It is especially important to talk with your doctor about diet pills, as they can be dangerous with liothyronine.

Take liothyronine medication on an empty stomach to avoid any possible interactions. Wait several hours before taking if you have had any antacids, calcium or iron supplements, or certain ulcer and cholesterol medications, as they can lesson the effects of liothyronine.

Wait at least four hours before taking this medication if you are on a high-fibre or soy diet. High-fibre and soy diets can impair the absorption of liothyronine, lessoning its effectiveness. Foods highest in fibre are peas, black beans, lima beans, bran and oats, lentils, and avocado. Soy milk and soybeans are two of the most popular soy products.

Avoid alcohol with liothyronine. Alcohol can lesson the effects of the medication and cause unwanted side effects, like impaired driving. Alcohol also has a lot of hidden calories, which can put weight on fast.


It is important to be in close contact with your doctor regarding any changes to diet, exercise routine, medications, or vitamins when taking liothyronine.
