Question to the Department of Health and Social Care:

To ask the Secretary of State for Health, if he will commission research on the potential effectiveness of liothyronine (T3) and natural desiccated thyroid for patients with hypothyroidism.

The National Institute for Health Research (NIHR) Collaboration for Leadership in Applied Health Research and Care (CLAHRC) South West Peninsula has partly supported a review of treatment for primary hypothyroidism published in 2012 in the journal Drug Design, Development and Therapy. The review considered approaches including triiodothyronine (liothyronine) therapy, trioodothyronine-levothyroxine combination therapy, and the use of natural desiccated thyroid.
