Switching from NDT to T3

So 7 months ago, after getting my labs done and seeing my FT3 and FT4 were ROCK BOTTOM and no doctor would help me, I decided to take matters into my own hands and started taking an NDT. I started at a low dose and worked my way up to 2 grains a day. I was feeling fantastic for about 3 weeks and then it all started to slowly come down. I eventually got my labs redone and it showed that while my FT3 and FT4 were now in optimal ranges, my RT3 was through the roof. I've read that you don't want your RT3 to be higher than 11.....mine was 25. So I immediately lowered my dosage to 1.5 grains per day, and this worked well for about another week but then I started feeling worse again. I may drop down to just 1 grain per day, but so long as I keep taking a medication that has T4 in it I think my RT3 will always be high. So I'm thinking about dropping the NDT and taking a pure T3 medication. Thoughts? And if I do switch to pure T3, how much should I be taking per day?

Any help would be greatly appreciated!

  • I was reading Paul Robinsons recent update to his using T3 only book and he was explaining why he thought he cannot use T4. It seems to boil down to lack of cortisol. T4 seems to use up more cortisol basically.

    Initially we feel good when we take thyroid hormone, but after just a few weeks we are not so good again.

    A possible solution is to try T3, but i would first see if you can generate more cortisol naturally using Pauls early morning T3 routine.

    This is where we wake in the middle of the night, usually around 4am and take a small amount of T3 to start with. I just use 3mcg T3 and this amount really helps me, but many other people need bigger doses. I think Paul takes 20cmg.

    You should always start with the lowest dose first and slow,y build up.

    If using NDT i would look at trying 1/2 a grain at this time and then taking the rest spread through the rest of the day.

    Obviously there may be other reasons to see why you are creating so much RT3. This maybe down to low iron, Vitamin D, or other nutritional difficiencies.

    Trial and error of different products, systems is the best way to regain health.
