Thyroid T3 ok T4 low

[johann]

Hi guys.
Just a little simple question.
My T3 is in a good range using Nature-Troid, but my T4 is low, do I get any benefit to rasie my T4 into normal range, or is it enough to have the T3 optimal?

what are you actual numbers and ranges of labs?

Free T4=0.8 (0.8-1.5)
Free T3=350 (210-440)
T3 =113 (76-181)
TSH =0.85 (0.35-4.0)
Ferritin =80 (25-336)

Been taking 75mg Nature-Throid 3x a day
Just raised it to 97.5mg 3x a day after this blood test.

T3 is the active hormone and is made from T4 and you have fair FT3 so no I don't think you need to do anything else.

I just had a consultation w Dr Saya about the same thing with my thyroid, my Free T3 was 4.5, and Free T4 0.89 2 hours after taking my dose.

His explanation for me was that since Natural Dessicated Thyroid is 4:1 T4:T3 I am converting T4 to T3 very well. Adding T4 to that would only get converted as well, making me hyperthyroid or could be converted instead to RT3 which we don't want. So as long as I am asymptomatic, it's fine.

Yes, I know that, I was just wondering if it would have any benefit, just if it would make me feel 2% better, or overall health. Thanks, I will just leave it, see how my next test comes out after raising it.

would not do a thing if you feel good. Numbers are good. I would run a RT3 next time to just make sure you do not have to much converting there.

Thanks, I already have done that, all good there to.

Note that saying it's "all good" doesn't amount to much given where lab ranges are, we deal in hard numbers from lab results.

RT3=12.0 (9.2-24.1)
Thyroglobulin Antibody=<1.0 (0.0-0.9)
TBO =8 (0-34)

so am I reading this correctly that you are now taking 7.5 grains of NDT per day? that is a big jump from your previous dose.

Hi Mark, Can't see where I did say that. But to clear it up I'm taking 97.5mg (1.5 grain) 3x a day that comes to 4.5 grain.

Johann, got it! my bad. PM me and let me know how the new level is going for you in a month. I am currently taking 2 grains in am and the 2 at 4pm daily. Trying to find the right level and just did full labs last week so waiting to see my numbers. I would have sent this PM but have not figured it out yet. Good luck!

Thanks Mark, will do.
