T3 (Triiodothyronine)

Triiodothyronine, or T3, is a crucial thyroid hormone that helps regulate many bodily functions, including metabolism, heart rate, and temperature. Produced by the thyroid gland, T3 plays a vital role in converting food into energy and supporting overall growth and development. It works in tandem with another hormone, thyroxine (T4), with T3 being the more active form. Maintaining balanced T3 levels is essential for good health; imbalances can lead to conditions like hyperthyroidism (too much T3) or hypothyroidism (too little T3), resulting in a range of health issues.
