Iodine

Iodine is a trace mineral that the body cannot produce on its own. It plays a central role in thyroid hormone production, which regulates metabolism, energy levels and normal growth. New Zealand soils are naturally low in iodine, which means many New Zealanders rely on fortified foods or supplements to meet their daily needs.

This collection includes iodine supplements in various forms including kelp-derived and potassium iodide options. Whether you are looking to support thyroid function, maintain healthy energy levels or address a confirmed deficiency, you will find suitable options here. Always check with your GP before starting iodine supplementation, particularly if you have an existing thyroid condition.

Why Iodine Matters for New Zealanders

New Zealand is one of the most iodine-deficient countries in the developed world. The volcanic soils across much of the country contain very little iodine, which means locally grown produce provides minimal amounts. Bread made with iodised salt is the main dietary source for most people, but this alone is often not enough for those with higher needs such as pregnant women, breastfeeding mothers and growing children.

Who May Benefit from Iodine Supplementation

Pregnant and breastfeeding women have significantly higher iodine requirements. The Ministry of Health recommends iodine supplementation during pregnancy and while breastfeeding. People who avoid dairy, seafood or iodised salt may also have lower intakes. Those experiencing fatigue, unexplained weight changes or difficulty concentrating may want to discuss iodine levels with their GP.

Common Questions

How much iodine do I need each day?

Adults generally need around 150 micrograms per day. Pregnant women need 220 micrograms and breastfeeding women need 270 micrograms. These amounts are difficult to achieve through NZ diet alone without iodised salt or supplementation.

Can I take too much iodine?

Yes. Both too little and too much iodine can affect thyroid function. The upper safe limit for adults is around 1100 micrograms per day. Avoid high-dose iodine supplements unless directed by a health professional, particularly if you have a thyroid condition.

What is the difference between kelp iodine and potassium iodide?

Kelp is a natural seaweed source of iodine and provides a range of trace minerals alongside it. Potassium iodide is a more concentrated and standardised form where the exact dose is easier to control. Both are effective for general iodine support.
