Your labs came back “normal.” But you’re still exhausted, cold, and can’t move the scale.
Here’s what most doctors aren’t checking — Free T3.
It’s the active thyroid hormone. The one your cells actually use for energy and metabolism. And your body has to convert T4 into T3 to get there. That conversion step is where things quietly fall apart.
Gut inflammation disrupts it. Chronic stress disrupts it. A compromised gut disrupts it.
When conversion is off, thyroid signaling shifts — and even a “normal” number on your panel won’t tell the full story.
This is why I look at conversion patterns, immune activity, stress physiology, and gut function together. Not just TSH. Not just T4. The whole picture.
If your Free T3 is sitting low-normal and you still feel off — comment T3 below and I’ll walk you through exactly what we look at next. 💛
