    I started taking less T4 and I tanked my Reverse T3 (RT3) below detectable levels

    I've always had pretty "good" RT3 results despite taking north of 100 mcg of T4 per day. The range is 9.2-24.1 ng/dL. I've had results as low a 7.4 while taking this much T4 (about 125mcg per day), and it typically coincided with lower cortisol results. So, this time, I had been experimenting...

    Lowest rT3 (reverse T3) result I've ever gotten: 7.4 ng/dL

    I have always had reverse T3 on the lowest end of the range, and this time it was below range: 7.4 ng/dL For the last month and half I have experimented with a 2:1 T4 to T3 ratio, taking 100 mcg of T4 and between 40 to 50 mcg consistently almost every day (split in 4 to 5 doses depending on my...

    For some years now my mom has been taking Levothyroxine (T4) for her hypothyroidism. She is also bipolar and takes Risperidone and Valcote (sodium valproate).

    Conversion Of T3 And RT3 To T2 PH Dependent

    [ edit : part of post moved from Anybody Know More On The Role Of Type 3 Deiodinase? ] I found this one by chance. Don't know if it helps. Conversion of T3 and rT3 to 3,3'-T2: pH dependency. - PubMed - NCBI

    Alzheimers And T3,Rt3

    Ray Peat has written and spoken about Alzheimers and dementia in general. These studies are small but very interesting, I don't understand why they don't check T3 and reverse T3 for Alzheimers.This is all I can find at the moment. Study showing T3 is low in Alzheimers patients . Low Levels...

    Is This Quote From RP On Excess T3 Correct? Can T3 Turn Into RT3?

    I know he apparently later clarified that Reverse T3 is from T4, but I am curious to know why he said the Liver is likely to convert much of the T3 as a defensive response? Is this true? An interesting mistake he made if its not true, thats for sure.
