Hi on 45mcg t3 split into 3 doses one day and 40 mcg the next day.I was feeling a lot better for 3 weeks now feel anxious hot face and hands heart pounding on exercise.Every time I go higher than 40mcg feel better for week or two then like this again.When I look back to where I became so ill all of a sudden after years of hashimotos,I feel that since been on t3 only a lot of the symptoms have gone,but still left with this odd feeling inside me and do not know what it is,My vit d came back it is 33 was 38,I just cannot get back to how I was ,how I would love to be back to how I felt 3 years ago ,even though that was mot great ,but could work and enjoy life.It is if there is a block or brick wall and some chemical is being released into my body.Odd I know .My pulse has been fine and no temp.Could it be I need to raise or just stay on 40 mcg ,at 40mcg my aches and pains tend to come back and it feels like it takes t3 a few weeks to build up in my system like t4 although I am aware it takes about 3 days with t3.

Susiebow, T3 gets into the cells quicker than T4 but it still takes a few weeks for FT3 levels to build. As 40mcg doesn't seem to be enough and 45mcg seems too much perhaps you could try 40mcg/45mcg alternate days.

VitD is replete >75 and most people are comfortable around 100. Supplement 5,000iu daily for 8 weeks then reduce to 5,000iu alternate days and retest in 4-6 months.

Susiebow, I'd drop to 40mcg daily to see whether the symptoms improve. Good vitD levels can aid T4 to T3 conversion but I don't think low vitD affects thyroid levels otherwise. Low vitD is likely to cause musculoskeletal pain and fatigue.
