NDT Thyroid S or Thiroyd

I'm switching to NDT, but it's a bit of a leap of faith. I've seen there's Thyroid S and Thiroyd. Is one easier to judge doses with, or any problems with one or the other? Any advice would be helpful.

Courses for horses I'd say. ThyroidS is slow release I take it and find it excellent. Others here prefer thiroyd which I think has fewer fillers but I speak with no experience of it - I tried ThyroidS it suited me and I have kept with it.

This gives information about what is actually in them:

I use Thyroid S. It's been good for me. At the time of my 'leap' I knew that there were more fillers in it than Thiroyd but all the reviews were good. I later read a few times about people questioning the consistency of manufacture of Thiroyd so just do your research. Moving from Levo to NDT was a life changer for me as I don't convert T4 to T3. Good luck!

Thanks. How did you move over. Part Levo, part Thyroid S, it straight to Thyroid S. Straight onto full dose or start small and build up?

I used the Thyroid patient advocacy guidelines reducing Levo by 25mcg and replacing with 1/4 grain NDT sticking to the time scale they suggested. At one point (1/2 grain) I had to split the dose or I felt odd but otherwise it just got better and better. Some people just switch but I think the T3 blast would have been too much for me. Also if it is no good you can quickly pull out.

I've just switched over and feel a bit odd. Bit spaced out. Maybe it's the T3.

Sounds like it could be. I had heart problems so had to be careful switching but my heart pains are much better now i. I felt spaced out and edgy when I took half a grain with 100 or 75mcg Levo so I took 1/4 am and 1/4 pm and felt ok again.

There's also TR man, but I know nothing about that. I tried Thiroyd and found it OK, but am now on T3 only.

From what I have read Thiroyd NDT is not costed but Thiroyd S is with no other difference.
