The Active Ingredient Is: Iodine (from kelp)

Iodine is a trace mineral basically needed for the production of thyroid hormones, which help regulate metabolism and energy use. This form is derived from whole kelp thallus (Ascophyllum nodosum), providing a natural iodine source inside a seaweed matrix.

The iodine in this product is sourced from ocean-grown kelp and exists as a bioavailable mineral content within the seaweed, contributing to a mineral profile that supports normal physiological processes.

What Does Iodine Do?

Iodine participates in the normal production of thyroid hormones, which are involved in metabolism and energetic balance. It supports normal growth and development processes through thyroid function as recognised in EFSA guidance.

This combination relies on natural iodine from kelp to support its primary role in thyroid hormone synthesis and overall mineral provision for normal body function.

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