In our body, a healthy gut microbiota directly impacts the immune function as well as thyroid function. The dysfunction of gut microbiota is now linked with Hashimoto's Thyroid condition and Grave's disease.
The gut microbiota can influence the availability of the micronutrients which are required for thyroid functioning. These micronutrients are often found to be deficient in autoimmune Thyroid conditions which can result in the malfunctioning of the thyroid gland.
Iodine, iron, and copper are crucial for thyroid hormone synthesis. Selenium and zinc are needed for converting T4 to T3, and vitamin D assists in regulating the immune response.
