T4 Thyroxine

Description

What is T4 Thyroxine?

All vertebrates have a thyroid gland. The thyroid produces a hormone called Thyroxine, which is known as T4.
This hormone plays a role in several of your body’s functions, including growth and metabolism.

Some  T4 exists as free T4. This means it hasn’t bonded to protein in your blood. This is the type available for use within a body,tissues etc. However, most of the T4 in the bloodstream is bonded to protein.

How to know if T4 levels are low subjects?

Because T4 exists in two forms in your body, there are two kinds of T4 tests: a total T4 test and a free T4 test.

A total T4 test measures the T4 that’s bonded to protein along with any free T4. A free T4 test measures only the free T4 in your blood. Because free T4 is what’s available to your body for use, a free T4 test is often preferred over a total T4 test.

Benefits of T4?

The #1 benefit of T4 is to regulate metabolism in subjects. This will regulate how their body uses energy and manages weight.
Research also shows that T4 supplements can possibly increase mitochondrial functions, basal metabolic rate, muscle mass production, body temperature, enzymatic functions, energy levels, and hair growth.

Some subjects even show signs in increase mental health.

How Does T4 Thyroxine Work?

The production of T4 is activated by the thyroid-stimulating hormone released by the anterior pituitary gland. As T3 and T4 bind to nuclear receptors, they are bounded to plasma proteins and then carried in the blood.

Thyroid cells are the only cells in the body which can absorb iodine. These cells combine iodine and the amino acid tyrosine to make T3 and T4. T3 and T4 are then released into the blood stream and are transported throughout the body where they control metabolism (conversion of oxygen and calories to energy).

A healthy thyroid produces around 80% T4 and 20% T3

Some potential side effects of to much T4 or T3 include increased appetite, palpitations, tremor, irritability, and increased bowel movements, among others.
