How Does Levothyroxine Work?

Levothyroxine UK is a man-made version of thyroxine or T4 hormone, naturally produced by the thyroid gland. A portion of this hormone gets converted into triiodothyronine (T3), the more biologically active thyroid hormone.

T3 and T4 encourage various functions, including body temperature regulation, metabolic rate, heart activity, digestion, and energy utilization. When thyroid hormone levels are too low, metabolism slows, potentially causing symptoms such as tiredness, weight gain, sensitivity to cold, dry skin, constipation, and difficulty concentrating.
