Iodine is essential for thyroid health, metabolism, energy, brain development, and possibly breast tissue health.
Your body cannot make iodine on its own, and low levels may contribute to fatigue, feeling cold, weight changes, hair thinning, dry skin, brain fog, and thyroid swelling.
While iodine can be found in foods like seafood, seaweed, beans, baked potatoes, and dried cranberries, levels can vary — which is why testing can be helpful.
More iodine is not always better, especially if you have thyroid issues or thyroid antibodies. Testing helps personalize your plan.
