Peter Attia's free T3 increased from 1.8 to 2.9, reverse T3 decreased from 38 to 14, and the ratio improved after an intervention.

“at a baseline my TSH was 2.4 yeah usually is a little bit lower than that but I'm happy my reverse t3 was 11 great my free t3 3.7 my ratio point 3 4 so feeling like a thyroid champ”

“testosterone actually went up a little bit it went in total testosterone which we rarely talk about since again it's sort of like talking about total cortisol it's kind of irrelevant but total testosterone went up from 764 to 920 and free testosterone went up as well even though sex more binding globulin went up with testosterone and so the free testosterone went from 15 and point five to seventeen point four and nanograms per deciliter again that's not a huge change but that does put me now at maybe the sixtieth or even 65th percentile”

“even though my thyroid function was still a little out of sorts it was moving back in the right direction so the free t3 went up from 1.8 to 2.9 the reverse t3 from 38 down to 14 the ratio point to 1”

“which if you're going to interpret that you might say well some thing there was some force you know something in my body was sort of wanting to slow my metabolism down”
