Potassium (Iodide) 800 mcg

New Roots potassium iodide contains 800 mcg of elemental iodine per capsule - the recommended daily intake - to protect the thyroid gland during periods of exposure to radioactive iodine.

The thyroid gland needs iodine for hormone synthesis, and absorbs all available forms of iodine. That's why saturating the thyroid with a safe, stable form of iodine prevents the absorption of radioactive iodine.
