Life Extension® strongly recommends getting the Thyroid Add–on Panel to the Male or Female Life Extension Panels, especially for those interested in weight loss. The thyroid gland primarily produces T4 which converts to T3, the more active form of the hormone.
Optimal thyroid hormone production supports your resting metabolic rate, which is essential in maintaining a healthy weight. This test includes measurements for free T4 and free T3.
If you are adding this panel to a Male or Female Life Extension Panel, you will need to fast for 12 hours. Drink plenty of water and take all medications as prescribed. Do not take your supplements the day of the test.
