Hormone Health Hub: Expert Insights on Testing, Balance & Better Living — thyroid wellness testing

At 24, Dr. Kate Placzek was sleeping 16 hours a day and barely functioning — yet her standard blood tests came back normal. It took a TSH result in the mid-thirties to finally explain her debilitating fatigue. In this candid personal account, she shares her thyroid diagnosis, what she learned about optimal TSH levels, and why testing beyond TSH alone can make all the difference.

Environmental pollutants are in the food we eat, the air we breathe and the water we drink — and in excess, they can profoundly disrupt thyroid hormone synthesis and action. This article explains how iodine and selenium deficiencies develop, how antagonists like bromine, arsenic and mercury exacerbate thyroid dysfunction, and why urine testing for these five elements can reveal the hidden environmental drivers of thyroid symptoms that standard blood tests miss.

Iodine deficiency is more common than many realise. This guide walks through how to assess iodine status using dietary recall, symptom profiling, and a three-part laboratory panel — including thyroid function, thyroglobulin, and urinary iodine and bromine testing.

Once iodine deficiency is confirmed through laboratory assessment, choosing the right supplement form is critical. This guide explains the difference between iodide and molecular iodine, how to dose safely, what to consider with Hashimoto's, and how to monitor your progress with at-home hormone testing.

Selenium is an essential trace element required for thyroid hormone activation, antioxidant defence and selenoprotein synthesis — yet it is one of the most commonly overlooked nutrients. Too little increases cancer risk; too much is toxic. This article explains the different forms of selenium found in food and supplements, which forms are best absorbed, their anti-cancer properties, and how to determine whether your selenium status is optimal.
