099: Guidance on what time of day it is best to take T4 and/or T3?

Masterjohn Q&A Files Episode 99


Carrie: It actually depends if you're taking immediate release T4 or T3 especially or sustained release because T4 has a much longer half-life which is why we traditionally say to take it in the morning since it helps with energy and metabolism and all those things. Although I do know some people choose to take their T4 at night before bed. But T3 has a very short half-life, and so what I'm finding is some practitioners are now doing what's called a sustained release T3. They take their T3 and it helps sustain longer throughout the day, or they will take their T3 twice. They'll take it in the morning and then they'll sort of take it again in the mid-afternoon.

Now, if you're taking a combination T4/T3 such as Armour or Nature-Throid, you can't get the sustained part. I do know some people who will take their Armour or their Nature-Throid in the morning, and then they will take in additional dose of T3 in the early afternoon like an extra, whatever it is, 2.5 or 5 micrograms of T3.
