Iodine Supplements

Iodine is one of the few minerals your thyroid genuinely cannot work without. The gland uses iodine to produce thyroxine (T4) and triiodothyronine (T3), the hormones that regulate metabolism, body temperature, and energy production. Without adequate intake, thyroid function slows.

Australia’s soils are notoriously low in iodine, and national surveys have found widespread mild deficiency across the population. Mandatory iodine fortification of bread was introduced partly in response, but many Australians still fall short of the recommended 150mcg daily intake. Pregnant and breastfeeding women need considerably more, up to 270mcg, as iodine is critical for foetal brain development.

An iodine supplement comes in several forms. Liquid iodine drops absorb quickly and are easy to dose precisely. Most people add them to a small amount of water or juice. Potassium iodide tablets offer a stable, measured dose. Kelp-based options provide iodine alongside other trace minerals from whole food sources, though iodine content can vary between batches.

Those who follow plant-based diets, avoid iodised salt, or live in inland areas tend to be at higher risk of low iodine status. People with thyroid concerns often ask how much iodine per day is appropriate for their situation. The standard adult recommendation is 150mcg, though individual needs vary and a healthcare practitioner can offer more personalised guidance.
