The thyroid is a small but powerful gland in your neck that plays a major role in regulating your metabolism, energy levels, and overall vitality. It produces hormones that influence how every cell in your body functions — especially when it comes to energy production and balance.
Your thyroid produces:
T4 (Thyroxine) – This is the main hormone produced by the thyroid, but it needs to be converted into T3, the active form, in order to support your metabolism and energy.
T3 (Triiodothyronine) – This is the active thyroid hormone that drives metabolism and supports cellular energy.
RT3 (Reverse T3) – This acts as a brake, blocking the effects of T3 when your body is under stress.
Calcitonin – Helps regulate calcium levels in your blood.
Your thyroid is closely connected to the Hypothalamus-Pituitary-Thyroid (HPT) axis, and imbalances can lead to underactive (hypothyroid), overactive (hyperthyroid), or autoimmune conditions such as Hashimoto’s or Graves’ disease. All of these affect how your body transports, activates, and responds to thyroid hormones.
