Understanding Thyroxine (T4)

Thyroxine, also known as T4, is a major hormone produced by the thyroid gland and is responsible for a variety of body processes, including metabolism. It’s important to understand the role of thyroxine and the foods and nutrients that support it during production and absorption. This can help ensure good health and keep your thyroid functioning properly.

What Contributes to T4 Production and Absorption?

To produce and absorb thyroxine, your body needs hormones and nutrients from food, such as iodine, selenium, zinc, and tyrosine. The body also needs certain vitamins, such as Vitamin A, E, B6, and B12, to help metabolize T4. Eating a variety of foods that are rich in these nutrients can support proper T4 production and absorption.
