The Active Ingredient Is: Iodine (from kelp)

Iodine is a trace mineral essential for the synthesis of thyroid hormones and normal metabolic regulation. This form provides iodine sourced from kelp, a natural marine source that contributes to the body's iodine supply.

This ingredient combines iodine from kelp with additional marine minerals that accompany the natural plant matrix, supporting the mineral profile of the supplement.

What Does Iodine Do?

Iodine plays a role in the production of thyroid hormones, which are involved in energy metabolism and normal hormonal balance. Scientific research suggests adequate iodine supports healthy thyroid function and metabolic regulation.

Dr. Patel of University of Cambridge found that iodine is required for the biosynthesis of thyroid hormones, highlighting its role in maintaining normal hormone production and metabolic activity.
