T3 (Liothyronine Sodium) is a synthetic form of the active thyroid hormone triiodothyronine, designed to regulate metabolism and support optimal energy utilization at the cellular level. It is indicated for the management of hypothyroidism and related metabolic disorders, helping restore normal physiological function when endogenous hormone production is inadequate. T3 acts rapidly to enhance metabolic activity, improve protein synthesis, and support cardiovascular efficiency. With its precise hormonal control, reliable bioavailability, and consistent therapeutic outcomes, T3 remains a trusted choice for professionals managing thyroid hormone replacement and metabolic restoration therapies.
