How Does Stress Affect the Thyroid?

How Does Stress Affect the Thyroid?

 •   Adrenal health is known to affect thyroid function.  The amino acid tyrosine is essential for the production of thyroid hormones and is also necessary for the production of steroid hormones adrenaline and noradrenaline.  When the body is under stress, more of these hormones are required and tyrosine reserves are depleted, leaving the thyroid hormone pathway under functioning.

 •   Stress also depletes many of the essential nutrients required for thyroid function – the B vitamins, vitamin C, zinc and selenium especially.  The conversion of thyroxine (T4) into active triiodothyronine (T3) requires the enzyme 5’deiodinase.  This enzyme requires selenium to function optimally.  A healthy conversion is also dependent on a number of nutritional cofactors that are used up rapidly under stress.  Stress can inhibit the enzyme’s ability to both produce and convert thyroid hormones throughout the body.

Individuals who are stressed may therefore require additional adrenal support in order to improve their thyroid function:

 •   Adrenal support begins by addressing the source of the stress; lifestyle changes to reduce and manage stress are the first port of call.

 •   Blood sugar balancing dietary changes are an essential step towards balanced adrenal health.  

 •   Supplementation with key adrenal support nutrients: B vitamins, magnesium, vitamin C, zinc and chromium.

 •   Consider adding adrenal glandular supplementation for comprehensive support

 •   Adrenal support can work synergistically alongside targeted thyroid support.
