What Is Lugol's Solution?

Lugol's Solution, sometimes called "strong iodine solution," is a liquid iodine formula first developed in 1829. It combines molecular iodine (I₂) and potassium iodide (KI) dissolved in purified water. As a dietary supplement, it's one way to add iodine — an essential trace mineral — to your daily routine.

Why Iodine Matters

Your thyroid gland uses iodine to produce thyroid hormones, which support normal metabolism and everyday energy levels. Because the body doesn't produce iodine on its own, it has to come from diet or supplementation.

How to Use Lugol's Solution

Lugol's Solution is taken orally, mixed into a glass of water, milk, or juice. Many people find it easier on the stomach when taken with or after a meal. Always follow the serving size printed on your product label, and do not exceed the recommended amount.

Who Should Talk to a Doctor First

Consult a qualified healthcare provider before starting any iodine supplement, especially if you are pregnant, nursing, taking prescription medication (including thyroid medication), or have a known thyroid condition or iodine sensitivity. Individual iodine needs vary, and a healthcare provider is the right person to help you determine what's appropriate for you.
