Thyroid Shorts Episode 15: Myth - Low fT3 Means You Just Need More T3

Episode 15 – Myth: Low fT3 Means You Just Need More T3 Many people struggling with chronic hypothyroid symptoms are told the answer is simple: "Your free T3 is low, so you just need more T3 medication." But is that really the solution? In this episode of Thyroid Shorts, Dr. Eric Balcavage explains why low T3 is often an adaptive response to stress, not a sign that your body is broken. He explores how gut health, diet, inflammation, and immune activity drive thyroid conversion, and why simply adding T3 may provide temporary relief but can worsen long-term issues. Key insights include: Why the majority of T3 is produced outside the thyroid gland How dysbiosis, leaky gut, and inflammation reduce conversion The risks of overmedicating with T3 (immune suppression, anxiety, palpitations, and more thyroiditis) Practical strategies to restore healthy T4-to-T3 conversion through gut and lifestyle support If you've been chasing "optimal labs" with more medication but still feel unwell, this episode will give you a new perspective, and tools you can start using right away.
