Potassium iodide is a highly bioavailable, well-studied form of iodine, an essential trace mineral the body cannot produce on its own and must obtain through diet or supplementation. Iodine is a foundational nutrient, best known for its role in the production of thyroid hormones, which help maintain metabolism, energy, and numerous developmental processes. Each serving provides 38 mcg, delivering 25% of the Daily Value in a stable, water-soluble form that is readily absorbed and utilized by the body.
Key Benefits of Iodine (as potassium iodide):
Supports healthy thyroid hormone production, which supports the body's normal metabolic processes.*
Helps maintain normal energy-yielding metabolism, supporting how the body converts food into usable energy.*
Why it Matters:
Iodine inadequacy is one of the most common nutritional shortfalls worldwide. In the U.S., shifting dietary patterns, including reduced use of iodized salt and lower dairy consumption, have contributed to declining iodine intake across many adults (Leung & Braverman, 2014).
Thyroid hormones influence far more than metabolism. They play a role in body temperature regulation, heart rate, mood, and the health of hair, skin, and nails, making consistent iodine intake relevant to everyday vitality.*
Women of reproductive age and those following plant-based diets are among the groups most likely to fall short of adequate iodine intake, as seafood and dairy, the richest dietary sources, may be limited or absent from their diets (WHO, 2007).
Potassium iodide is the gold-standard form used in food fortification programs globally, chosen for its stability and reliable absorption compared to other iodine compounds.
