The thyroid gland is an endocrine gland situated in our neck just below the Adam’s apple. It makes two hormones that are secreted into the blood: thyroxine (T4) and triiodothyronine (T3). The release of these hormones influences the metabolism of the cells in our body, which impacts our weight, energy, temperature control, concentration and mood. British Thyroid Foundation. (n.d.).
