Hormone Health Hub: Expert Insights on Testing, Balance & Better Living — iodine and hormone balance

Iodine is an essential trace element required for thyroid hormone production, yet many people are unknowingly deficient. While iodised salt and seafood are well-known sources, dairy products, eggs, and seaweed also contribute significantly to daily intake. Changing dietary habits — including reduced milk consumption and the replacement of iodine with bromine in bread production — are quietly lowering iodine intake across the population. This article explains where dietary iodine comes from, why the body needs it, how it is absorbed and excreted, and how at-home urine testing can confirm whether your intake is adequate.

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.

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.
