The Active Ingredient Is: Potassium Iodide

Potassium iodide is a mineral form used to supply iodine, an essential nutrient involved in thyroid hormone production and metabolic regulation.

In this tablet form, potassium iodide provides a highly bioavailable source of iodine; the product is designed for short-term, vegetarian-friendly use and contains supplementary calcium as part of the formulation.

What Does Potassium Iodide Do?

Potassium iodide is involved in the synthesis of thyroid hormones, supporting normal thyroid function and metabolic processes in daily wellness contexts.

Research indicates that iodine plays a role in thyroid hormone production and that potassium iodide is the preferred form for thyroid uptake in emergency protection scenarios when rapid iodine availability is needed. Dr. Reiners of a major university notes these mechanisms as part of regulatory guidance and clinical practice.
