What began as a personal health crisis for McCall McPherson quickly evolved into a lifelong mission to help others reclaim their health. At just 27, she was exhausted, overlooked, and dismissed by conventional medicine—even after being diagnosed with a thyroid condition. It wasn’t until she sought out integrative care that her health dramatically turned around. Inspired by her own healing, McCall dove deep into thyroid science, studied under expert mentors, and eventually founded Modern Thyroid Clinic, where she now helps thousands of women get their lives back. Her clinic focuses on optimizing thyroid function—not just checking outdated lab values—and has seen tremendous success with even the most complex cases.

In her conversation with Christian, McCall discusses why most standard thyroid tests are failing patients. While conventional care typically relies solely on TSH, true thyroid health requires a deeper look at a full panel—including free T3, free T4, reverse T3, and thyroid antibodies. Symptoms like fatigue, brain fog, weight gain, and hair loss are often brushed off, but McCall has found that when these signs are addressed holistically, patients often experience complete transformation. According to her, more than 90% of her patients—many of whom have seen multiple doctors with no results—go on to regain full energy, mental clarity, and metabolic balance.

They also explore the incredible synergy between thyroid health and stem cell support. As Christian shares, there are remarkable stories of individuals recovering thyroid function even after partial removal or long-term damage—thanks to the regenerative power of their own stem cells. This new frontier of healing could radically change what’s possible for those living with Hashimoto’s, post-surgical hypothyroidism, or other autoimmune thyroid conditions. In an exciting development, McCall and Christian announce a collaborative research project to explore how stem cell stimulation through natural means could help rebuild thyroid tissue and restore function.

Ultimately, McCall’s message is one of hope, empowerment, and education. She urges women to stop settling for “normal” labs when they still feel unwell—and to advocate for deeper, data-driven, and more compassionate care. As both she and Christian agree, it’s time to bring a new level of science, curiosity, and humanity into how we approach thyroid health—and the future looks incredibly bright.
