In this episode of Modern Thyroid Wellness, McCall McPherson unpacks one of the most common frustrations in thyroid care: why levothyroxine-based medications (like Synthroid) often leave patients feeling unwell, even when their labs look “normal.” Drawing from her own experience as a thyroid patient and her extensive clinical work, McCall explains the flawed assumption that every body seamlessly converts T4 into active T3—and why that’s simply not the case for many people.
She breaks down the three stages of levothyroxine treatment, reveals the gaps in standard thyroid testing, and explains how adding T3 therapy can change everything. This episode is a must-listen for anyone who feels unheard, dismissed, or stuck in their thyroid journey—and wants practical, actionable advice for regaining energy, balance, and hope.
