Synthetic T4

Synthetic T4, or synthetic thyroxine, is a man-made version of the thyroid hormone thyroxine (T4) produced by the thyroid gland. It helps regulate metabolism and energy levels in the body. People who have an underactive thyroid, a condition known as hypothyroidism, may not produce enough T4 naturally. In such cases, doctors often prescribe synthetic T4 to help normalize hormone levels, improve energy, and maintain overall health. This treatment is crucial for managing symptoms like fatigue, weight gain, and mood changes associated with low thyroid hormone levels.
