I wonder if anyone has any advice. I have some persuaded my endo to let me trial T3 and have started taking it today. I am switching from 125 mcg of levo to 75mcg lev and 2x10mcg t3 per day. I supplement with vitamin b12, vitamin d, selenium, magnesium, k2 and iron ( not all at once!). I was wondering if there is anything I should watch out for or if anyone has a suggestion of how I should split the doses?
