I took my temperature this morning and it was 96.2 F. I just took it again after taking iodine and it is 98.5 F. Is that good?

An increase in temperature from 96.2 F to 98.5 F is a good sign. You'll want to check and monitor your temperature regularly, especially once you start taking both the iodine and selenium consistently. I like to see temperature consistently between 97.8 and 98.6 F. Your original temperature is too low but it's what I would expect considering you have hypothyroidism. Anything less than 97.8 F suggests hypothyroidism. The iodine and selenium should help correct this.
