Episode 127: [The LOdown] Low T3 With Normal TSH: How Energy Availability Impacts Thyroid Function

Low T3 With Normal TSH: How Energy Availability Impacts Thyroid Function If your TSH looks “normal” but you still feel exhausted, with irregular cycles and slowed metabolism, this episode will help you understand what standard testing often misses. In this episode, we break down energy availability—the balance between the energy you take in and the energy your body expends—and why it is one of the most overlooked drivers of thyroid dysfunction, particularly low T3, the active thyroid hormone that actually controls metabolism, energy, and the menstrual cycle. A few things we chat about in this episode 👇👇👇 What T3 (active thyroid hormone) actually controls in the body How you can have normal TSH and T4 but still feel exhausted The connection between low energy availability and suppressed T3 Key variables that push the body into metabolic conservation mode Why adequate nutrition is essential for T4 → T3 conversion Hormones that inhibit thyroid function under stress or low fuel states Common signs and symptoms of low T3 Why thyroid medication alone often falls short How fueling, timing, and safety signals support thyroid and hormone restoration If you are an active woman, athlete, or high-performing individual struggling with fatigue, stubborn symptoms, or “normal” TSH levels that don’t match how you feel, this episode will give you a new framework for understanding—and supporting—your thyroid from the inside out.   Important show links 👇👇👇 Find out if you may be experiencing low T3 levels - Take our t3 quiz Uncover the labs that influence T3 levels - Get my Thyroid Inflammation Lab Decoder Guide Follow me on Instagram Rate the show!
