Thyroid Hormones

Definition

Thyroid hormones are chemical substances produced by the thyroid gland that regulate metabolism, energy levels, and many important bodily functions.

Scientific / Technical Definition

Thyroid hormones, primarily thyroxine (T4) and triiodothyronine (T3), are produced by the thyroid gland. They play a crucial role in regulating the body's metabolic rate, heart function, digestive function, muscle control, brain development, and bone maintenance. Their production is controlled by the thyroid-stimulating hormone (TSH) from the pituitary gland.

Benefits

• Regulate metabolism and energy levels
• Support proper development and differentiation of cells
• Maintain normal heart and digestive functions
• Contribute to muscle control and bone health

Examples

• Seafood, which is a source of iodine, necessary for thyroid hormone production
• Dairy products
• Eggs

Additional Information

• Importance: Thyroid hormones are vital for maintaining the body's metabolic balance and supporting vital organ functions. A deficiency or excess can lead to conditions such as hypothyroidism or hyperthyroidism.
