NDT T4 does it matter?

8 Replies

Hello I am on 2.5 grains NDT and quarter to half T3. I deliberately reduced from 3 grains because I seemed to rT3 crash (go very hypo suddenly). I have never tested positive for antibodies or inflammation. Does it matter if my T4 is lower end or should I try to up my NDT slightly. I have a mutated Dio2 so conversion is an issue.

Any thoughts welcome!

Shingleway,

Most people increase dose when they feel hypo, not reduce. The T3 in NDT and Liothyronine you are taking will overcome poor T4 to T3 conversion.

FT4 is almost always a lot lower on NDT than on Levothyroxine, sometimes below range. It doesn't matter that FT4 is low when FT3 is good and as your FT3 is in the upper range so you will be overmedicated if you increase dose.

Thanks Clutter! I feel good and added the T3 on reducing the NDT. Feel better and more stable. So will keep going!

Shingleway,

Feeling good is the best guide to dosing. I would never adjust dose according to blood results as long as I felt good.

So true!

Just a question please do you take the NDT and T3 together in the morning or what?

Hi I take them through the day. Typically 6am 11am and 3pm. Some people like to take some in the evening because it helps them sleep.

Thanks for the information.
