My understanding is the RDA is the bare minimum to avoid obvious symptoms of deficiency, and that everyone does better with 500 to 1000mcg. I think there's a case to be made for being cautious about getting too much supplemental iodine - I've read reports on /r/iodineprotocol of people who started taking mega-doses and aren't doing so well. I take 400-600mcg of iodine every other day. This is 2-3 drops in water. The carrier is ethanol. Pure iodine doesn't dissolve in water, so the drops become a cloud when dispensed into water.
