The conversation around T3 is one of the most confusing — and divisive — topics in thyroid care.

Conventional medicine often ignores T3 entirely.
Integrative and functional medicine frequently treats free T3 as the number that must be optimized at all costs.

Patients are left stuck in the middle, unsure who to trust, what their labs actually mean, and whether a "low" free T3 is something that needs to be fixed.

In this episode of Thyroid Answers, Dr. Eric Balcavage breaks down what free T3 really represents, where T3 actually comes from, and why lower free T3 is often an adaptive, protective response, not a sign of failure or deficiency.

You'll learn:

• Where T3 actually comes from — and why most of it isn't made by the thyroid

• The difference between thyroid homeostasis and thyroid allostasis

• Why the body intentionally reduces T4-to-T3 conversion under strain

• How free T3 and total T3 tell different stories — and why both matter

• Why raising free T3 can feel better short-term but worsen physiology long-term

• When lower free T3 is actually the body's solution, not the problem

• How to ask better questions instead of chasing numbers

This episode is not about protocols or "optimizing labs."
It's about understanding state, adaptation, and recovery — so you stop fighting your physiology and start working with it.
