I think this is the best source of Iodine available...tastes great and its pure vegan and no chemicals :) what's interestingi, I read that nascent Iodine is:
"a consumable form of Iodine that holds an electromagnetic charge. It allows for a larger release of energy once consumed, and is very similar to bio-available forms of iodine that are produced naturally in the thyroid gland. Because of this, your body is able to recognize and assimilate it very easily"
