Thyroid Stimulating Hormone (TSH)-Critical to your metabolism, thyroid function affects your energy level, heart rate, weight control, plus more. The thyroid-stimulating hormone is produced in the pituitary gland and serves to stimulate the production and release of thyroid hormones thyroxine(T4)and triiodothyronine (T3). The TSH helps identify an overactive or underachieved thyroid state.
