High, your husband should increase the Iodoral to at least 100 mg per day if he is diabetic. One of the doctors ( Fleches?) also recommends 100mg/day. I experienced a 25% decrease in blood gulcouse levels ( 30 day avg) 106 avg dropped to 80, at 100 to 150 mg day. My gulcose levels have been consistly in the 80-85 range for over 3 months now.
Iodine appears to reopen/open the insulin resistant cells, which can be one of the causes of Type2.
