I'm not an expert with high RT3, but often the patient has to discontinue the T4 med and take only the T3 med, at higher doses.
When FT4 is converted, it converts to both FT3 and RT3. RT3 is a mirror image of FT3, but can't be used at the cellular level; it can dock upside down in the T3 receptors, though, preventing the FT3 from getting in. Discontinuing the T4 med, will stop the conversion to T4 to RT3. The T4 med would, then, be resumed at a later time.
ooppps.....I meant high RT3. I do take 15mcg cytomel along with 125 synthroid, but maybe I just need more T3. We'll see what the dr thinks.
I haven't been taking any B12 or Vit D. I will add that daily and see if it helps. Thanks!
Where was the high FT3? Did you mean RT3? You may need just T3 med (cytomel, or generic) to get past the high RT3.
Your vitamin D is low in the range; vitamin B12 is mid range, which for me, is not high enough; I have to inject weekly, in order to keep my B12 at or above the top of the range.
