Iodine is a crucial nutrient that plays a vital role in maintaining optimal thyroid function and metabolism. While iodine is naturally found in some foods like seaweed, dairy, and fish, many people may not get enough through their diet alone. Iodine supplements can be a helpful way to support healthy metabolism and thyroid function. These supplements come in various forms, including tablets, capsules, and drops, and are available in both synthetic and natural forms. It's essential to speak with a healthcare professional before starting any supplement regimen to ensure it's safe and appropriate for individual needs.
