Thyroid gland produces two type of hormones T3 and T4. These hormones are necessary for all the cells in your body to work normally.

  • T3 – Triiodothyronine: This hormone contains three atoms of iodine and is often called T3.
  • T4 – Thyroxine: This hormone contains four atoms of iodine and is often called T4.

A normal thyroid gland produces about 80% (T4) and about 20% (T3). When the level of hormones drops very low, your heart rate may slower than normal and if it shoots up high then you may have a rapid heart rate. Therefore, to balance T3 and T4 hormones TSH plays a vital role.
