Does everyone need to get up to 500mcg iodine/day? How do you know when you are at your ideal dose and can stop increasing?

No, not everyone needs to get up to 500 mcg of iodide. It depends on the person's thyroid markers and the iodine result from their hair test. The ideal dose is determined by looking at thyroid markers and the iodine result from their hair test. If someone is taking 500 mcg per day and their test results are still not within the optimal range, then they could increase to 600-650 mcg per day.
