Liposomal Iodine

Iodine plays a crucial role in the body by supporting the production of thyroid hormones, which regulate many vital processes including metabolism, energy generation, and body temperature.

These hormones, primarily thyroxine (T4) and triiodothyronine (T3), are essential for normal growth, neurological development and the functioning of key organs. Iodine is especially important during pregnancy and infancy, as it supports healthy brain development in the growing baby.

Without enough iodine, the thyroid gland can become enlarged (a condition known as goitre) and overall hormone production may decline, leading to symptoms such as fatigue, weight gain and sensitivity to cold. Because the body does not produce iodine on its own, it must be obtained through diet or supplementation to maintain optimal health.

When taken in the context of radiation exposure, particularly following a nuclear incident that releases radioactive iodine isotopes, potassium iodide works by saturating the thyroid gland with stable, non-radioactive iodide. By flooding the thyroid with this readily available form of iodine, the gland becomes “full” and is far less likely to absorb the harmful radioactive iodine circulating in the bloodstream.

This selective uptake blockade helps protect thyroid tissue from radiation damage and significantly reduces the risk of developing thyroid cancer or other long-term thyroid dysfunction associated with radioactive iodine exposure. Of course, it’s important to follow public health guidance on dosage and timing, as the protective effect of potassium iodide is both dose and time-sensitive.

Daily iodine supplementation can be safe and beneficial when taken at appropriate levels to meet but not greatly exceed the recommended intake. Most adults require around 150 µg of iodine per day, a target easily achieved through a balanced diet that includes iodized salt, dairy, seafood, or seaweed. In populations where dietary iodine is low, a daily supplement can help prevent deficiency and support healthy thyroid function.

Yes, potassium iodide is a widely used and effective source of iodine. It consists of potassium and iodine, and when ingested, it dissolves in the stomach to release iodide, the form of iodine the body absorbs and uses.
Once absorbed, iodide travels through the bloodstream to the thyroid gland, where it supports the production of essential thyroid hormones. These hormones regulate metabolism, energy levels, and various aspects of growth and development. Potassium iodide is commonly used in supplements and medical treatments because it is stable, well-tolerated and provides a reliable, bioavailable form of iodine.
