Did you mean Thyroid Hormone?

Glossary Thyroid Hormone

regulates metabolism and energy production in the body

Thyroid hormone refers to the hormones produced by the thyroid gland, primarily thyroxine (T4) and triiodothyronine (T3). These hormones play a crucial role in regulating metabolism, energy production, and overall growth and development. Imbalances in thyroid hormone levels can lead to conditions such as hypothyroidism or hyperthyroidism, which can affect various bodily functions, including hair growth and health.
