Hormone Health Hub: Expert Insights on Testing, Balance & Better Living — thyroid support nutrients

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.

Iodine is an essential component of thyroid hormones T3 and T4, and plays a broader role in antioxidant defence and breast health. Yet many people are unknowingly deficient. This guide covers the recommended daily allowances for different life stages, the best dietary sources of iodine — from kelp to cod — and when testing your iodine and thyroid levels may be warranted.

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.
