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!

[The LODown] Is Your Low Progesterone Actually a Thyroid Issue? Low progesterone is one of the most common hormone concerns I see—but it’s also one of the most misunderstood. In this episode, we unpack why low progesterone is rarely a true progesterone deficiency and is far more often a downstream signal of poor ovulation quality driven by low T3, metabolic stress, or thyroid autoimmunity. You’ll learn why progesterone is best understood as a marker of ovulation strength—not something the body simply “fails to make”—and how thyroid hormone, mitochondrial energy, inflammation, blood sugar, and nervous system safety all determine whether ovulation (and the corpus luteum) can function properly. We also dive into why luteal phase defect is frequently misdiagnosed as PCOS, how Hashimoto’s can quietly disrupt ovulation even with normal cycles, and why progesterone supplementation alone often fails to fix the problem.   A few things we chat about in this episode 👇👇👇 Why progesterone reflects ovulation quality—not ovarian failure The thyroid–progesterone axis and how low T3 weakens ovulation and the corpus luteum How stress, cortisol, and reverse T3 put metabolic “brakes” on progesterone production The overlooked role of thyroid autoimmunity in low progesterone, short luteal phases, and miscarriage risk Luteal phase defect vs. PCOS: how to tell the difference  What labs actually matter for identifying thyroid-driven low progesterone (and how to time them correctly) Why progesterone supplementation is sometimes helpful—but rarely a root-cause solution Treatment priorities that restore ovulation by fixing thyroid conversion, metabolism, and immune stress    Important show links 👇👇👇 Take my free T3 QUIZ to find out if low t3 could be driving your low progesterone levels Episode Period Problems: PCOS vs. Amenorrhea   Book your 1:1 Functional Clarity Session www.functionalfueling.com/clarity-sessions Get discount with inito using code functionalfueling15 Follow me on Instagram Rate the show!
