How do you know if you are getting the right amount of iodine?
Iodine is essential for producing thyroid hormones and supporting metabolism, energy, temperature regulation, growth, and brain function. It is also concentrated in breast tissue and may be particularly important when thyroid concerns or toxin exposure are present.
Possible signs of low iodine include fatigue, weight gain, feeling cold, dry skin, hair thinning, weakness, memory difficulties, and swelling in the neck.
Food sources include seafood, baked potatoes, and dried cranberries. However, the iodine content of food can vary, making testing and precise supplementation more reliable than trying to estimate your intake.
Most people do not require a large amount of iodine, and taking too much without guidance can negatively affect thyroid function. Your optimal level may differ depending on thyroid antibodies, hypothyroidism, toxin exposure, immune concerns, and other health factors.
We recommend testing twice per year until you reach your personalized optimal level, followed by a urine test once per year.
