The Active Ingredient Is: Iodine

Iodine is a trace mineral essential for the production of thyroid hormones that regulate metabolism and energy use. This form is derived from Atlantic kelp, providing a natural marine source of iodine to support normal thyroid function and overall vitality. The mineral also supports growth and development through its role in hormone synthesis.

What Does Iodine Do?

Iodine helps normal thyroid hormone production, which regulates metabolism and energy use. NHS and EFSA recognise iodine's role in thyroid function; kelp provides a natural iodine source that supports this normal physiological process. This aligns with established recommendations for adults.

This supplement is not intended to diagnose, treat, cure, or prevent any disease.

Dietary supplements are not a replacement for a balanced diet. Do not take more than the recommended amount. Keep in a cool, dry area away from light and heat. Ensure they are out of children's reach and view.
