we are all under the impression that FBD requires I2. there is no I2 in SSKI . any I2 will do. Lugols is the proven curative. my personal chioce is for SSKI and magnascent, taken separately.
if I2 is what does the trick, then it is taking small amounts throughout the day that will really be most effective.
SSKI 2% is also a good choice for this as for price and convenience, but i think the magnascent is better.
