The thyroid gland is part of the endocrine system and is responsible for controlling the metabolic rate (or pace) of all the processes in the body. If there is a deficiency of circulating thyroid hormones, thyroxine (T4) and triiodothyronine (T3), every function of the body tends to slow down. Conversely if there is over production of thyroid hormones, the metabolic rate speeds up.

Your thyroid requires vital nutrients to produce thyroid hormones. If you are deficient in these nutrients, the thyroid may not function optimally. Read our published medical paper here about how optimising nutrient levels can restore thyroid function. Knowing your levels will allow us to tailor your recommendations and supplements for you to maintain good thyroid health.
The most common cause of hypothyroidism alongside autoimmune conditions is a deficiency in iodine. It is important to know your iodine levels before you supplement as where some people are deficient, others have excess iodine and over-supplementing may have adverse effects including promoting thyroid antibodies.
Selenium, zinc and magnesium play a critical role in the production of thyroid hormones. Deficiency in these or iodine can be a major cause of hypothyroidism and if identified, can be supported through nutritional modifications and supplements if necessary.
This is a crucial vitamin in modulating the immune system. Both excess or deficiency states have negative effects on your immune cells and maintaining the correct levels is important in immune-mediated thyroid conditions.
