Iodine is an essential mineral that your body relies on to keep thyroid hormones in check, which regulate energy, metabolism, and overall hormonal balance. Since your body cannot produce iodine, you need to get it from food to avoid issues like goiter, fatigue, and slowed metabolism. Including iodine-rich foods in your meals is a natural, practical way to ensure your thyroid is functioning properly. While supplements exist, relying on whole foods adds other nutrients that benefit your overall health. From seafood to dairy and even some plant-based options, there are plenty of ways to make sure your diet supports this vital mineral.
