Most doctors only test TSH. It’s the standard, it’s what insurance covers, and it’s what most practitioners are trained to assess. But TSH only gives you a surface-level view of thyroid function.
What actually determines how you feel is Free T3 — the active thyroid hormone your cells use for metabolism, energy, and mood. You can have a “normal” TSH and T4, yet still experience low thyroid symptoms if Free T3 is low or not being properly converted.
This is why so many people are told everything looks “fine” when they clearly don’t feel fine.
If you’ve been struggling with fatigue, weight changes, brain fog, anxiety, cold hands/feet, or hair thinning, you may need a deeper look.
