half life T3 in NDT

I've read over a period of time that T3 has half-life of anywhere from 2-2.5 days. I have, always, assumed (bad thing!) that was for synthetic T3. Anyone know, if that time-frame is applicable to dessicated T3? My FT3 shot up from 2.7 in late Feb. to 3.85 2 weeks ago. I had increased dose from97.5 every other day to 97.5 everyday. What I noticed was a wave of fatigue would come over me & when I ate (tho did not necessarily feel hungry), I felt like a wilted flower that had just been watered. Had gustatory thermogenesis (warm/hot after eating). I like how I feel w/my FT3 around 2.8, 2.9 I have a lot of labs I can post, if necessary to answer the ? I do supplement w/VtD, K2-MK7, Vit C & because my folate was 37 (15-150) I am now taking iron supplement (20mg capsules) 2x/wk Ever since Nature-throid w/drew ....... Thank You!!

I hope that is a typo!

That would be a very odd reference interval (range) for folate. AND folate has almost nothing to do with iron. Did you mean, as seems likely ferritin?
