Thiroyd Dosing??

Hey everyone

Today I just got my Thiroyd tablets from Thailand in the mail. Does anyone know what dosage 1 tablet is ? For example, is 1 tablet considered to be 1 grain? Is 1/2 tablet considered to be 0.5 grain. I just wanted to make sure because I am switching from 50 mcg synthroid. Any advice would be appreciated.

NOTE: I am on regular Thiroyd NOT Thiroyd-S ( just thought I would mention)

Hi, according to the Table in Izabella Wentz book 1 grain (or 1 tablet) is equivalent to 100mcg of Synthroid. Half a grain would therefore be equivalent to 50mcg of Synthroid. As you are already taking replacement hormone you can just do a straight swap but remember Thiroyd has the active T3 in it.

I don't think there is any difference between Thiroyd and Thiroyd-S in terms of potency, some people prefer one or the other but Thiroyd-S does have more fillers than Thiroyd.

Hope all goes well for you.

Thanks Cassie...its good to know about the fillers!

One tablet is one grain or NDT or about 65mcg levo equivalent - using the measure of T3 being T4 x 3. 35 mcg T4 and about 8.5 mcg T3 = 35+26 approx = 61mcg. Even if you think t3 is T4 x 4, it only comes to 35+34 = 68.
