The purported "authorities" recommend 0.150 milligrams a day.
So, 200 mg a day is like..... about 1300 times the "recommended" amount.
Its interesting to read the Physicians Desk Reference entry for "PIMA(TM) Syrup"
Last time I checked a person would receive 1200 milligrams of Iodide in one day, if following the recommended directions.
