Episode 215: Total T3 And Free T3 – What They Mean, What They Don’t, and Why Treating T3 often backfires

T3 is the most talked-about thyroid hormone — and the most misunderstood.

In this episode of the Thyroid Answers Podcast, Dr. Eric Balcavage breaks down Total T3 and Free T3 using a clear, Q&A-style format to address the most common questions, mistakes, and treatment traps patients and clinicians fall into.

You'll learn:

• What T3 actually represents — and what it does not

• The difference between Total T3 and Free T3 (and why you need both)

• Why low T3 is often an adaptive response, not a deficiency

• Why adding T3 medication can help short-term but worsen physiology long-term

• Why "chasing Free T3" is one of the biggest mistakes in functional medicine

• How stress, inflammation, illness, dieting, and medications alter T3 levels

• Why labs can improve while patients feel worse

• How to interpret T3 correctly within the full thyroid panel

This episode is essential listening if:

• You've been told your T3 is "low-normal" but still feel terrible

• You feel better on T3 medication at first — then worse

• Your labs look good, but your symptoms don't match

• You want to understand thyroid physiology beyond numbers and ranges
