Okay thank you. I monitor my temps and am taking synthroid. My temp goes up to 98.6.

They both kinda do

The T3 is the basal temp regulator but the T4 converter into T3 can control where that level is at.

Does that help you understand?

T$ is converted by the body to T3. The portion of T3 that is not bound to protein molecules is called free T3. This FT3 regulates metabolism (temperature) and many other body functions.
