The Active Ingredient Is: Iodine (Potassium Iodide)

Iodine is a trace mineral essential for making thyroid hormones that help regulate energy use and metabolism. This formula delivers iodine from potassium iodide, a form quickly absorbed by the body.

In the body, iodine is concentrated by the thyroid and woven into thyroglobulin for thyroid hormone production, supporting normal endocrine function and metabolic processes.

What Does Iodine Do?

Iodine helps with normal thyroid hormone production, which helps regulate energy use and cellular metabolism. EFSA notes that iodine is needed for normal thyroid function, contributing to standard metabolic processes.

This information mirrors established nutritional science on iodine and thyroid function as part of healthy body regulation.
