T4is also known as L-Thyroxine T4 and is available in several prescription formulations. It’s one of two primary hormones your thyroid produces, the other being triiodothyronine, or T3, although T4 makes up 90 percent of thyroid hormone. Every cell in your body depends upon thyroid hormones to regulate their metabolic function. If the thyroid gland does not produce sufficient T4, then you may develop symptoms of hypothyroidism; too much T4 leads to hyperthyroidism, according to the American Thyroid Association.
