15 Powerful Foods for Thyroid Health

The thyroid gland, located at the base of your neck, plays a crucial role in regulating various bodily functions, including metabolism, energy production, and hormone balance. It produces two essential hormones, triiodothyronine (T3) and thyroxine (T4), which control the rate at which your body uses energy. When your thyroid is not functioning properly, it can lead to several health issues, including hypothyroidism (underactive thyroid), hyperthyroidism (overactive thyroid), and autoimmune conditions like Hashimoto’s thyroiditis or Graves’ disease.

A healthy diet rich in specific nutrients can help support the thyroid gland and promote overall hormone balance. In this article, we will explore 15 powerful foods that can naturally boost thyroid health by providing the essential vitamins and minerals needed for optimal function.
