Triiodothyronine supplementation

Triiodothyronine (T3) is a hormone produced by the thyroid gland that helps regulate the body's metabolism, energy use, and overall function. Supplementing with T3 may be prescribed for certain thyroid conditions where the body isn’t producing enough hormone, like hypothyroidism, to restore normal metabolic activity. It is carefully controlled by a healthcare provider because inappropriate use can cause symptoms of excess hormone, such as rapid heartbeat, anxiety, or weight loss. T3 supplementation requires precise dosing and monitoring to ensure the body receives adequate hormone levels without adverse effects.
