1. Supports thyroid health: Iodine is essential for the production of thyroid hormones, which play a vital role in regulating metabolism, energy levels, and overall bodily functions.
2. Boosts immune function: Adequate levels of iodine are crucial for a properly functioning immune system, as it helps to protect against infections and diseases.

The Active Ingredient Is: Iodine (Potassium Iodide)

Iodine is an essential trace mineral that helps with the normal synthesis of thyroid hormones, which help regulate metabolism and energy use in the body.

This form uses potassium iodide, a steady source of iodine that is readily absorbed and utilised by the body. The product provides the iodine needed to support thyroid function through steady, bioavailable intake.

What Does Iodine Do?

Iodine helps with thyroid hormone production, which is involved in regulating metabolic rate and energy balance in the body. Studies suggest iodine supports brain development in children and cognitive function in adults, showing iodine's contribution to normal physiological processes. Dr. Zimmermann from Wageningen University found that iodine is a core component of thyroid hormones that influence metabolism.

The information aligns with EFSA and NHS guidance on iodine's role in supporting normal thyroid function and metabolic regulation.
