Iodine Synergy™ contains potassium iodide at a therapeutic dose of 10 mg to support thyroid function, including healthy thyroid hormone production and breast and prostate tissue health. The typical supplementation range is 10 to 50 mg until normal iodine ranges are observed in testing. Potassium iodide is a weak salt that readily separates in the gut, leaving free iodide ions to recombine to form I2 iodine, which is also required in the breasts and prostate for optimal health.
