May 26, 2026

In this episode of New Frontiers in Functional Medicine, Richard Horowitz joins Kara Fitzgerald to explore the connection between persistent infections, inflammation, and chronic disease. The discussion highlights emerging research linking Borrelia burgdorferi (Lyme disease) to amyloid production and Alzheimer’s biomarkers, along with the clinical implications of Dr. Horowitz’s MSIDS model. Topics include biofilm persistence, co-infections, treatment resistance, and multi-targeted strategies...

How He Reversed MS & Beat a Stroke | Montel Williams

May 15, 2026

Montel Williams joins Dr. Kara Fitzgerald to share his decades-long journey with multiple sclerosis (MS), including early neurological symptoms that preceded his diagnosis by years and his recovery following a hemorrhagic stroke. In this episode, created in partnership with MitoQ, the conversation explores MS through a functional medicine lens, with a focus on neuroinflammation, oxidative stress, and mitochondrial dysfunction as key drivers of fatigue, cognitive decline, and disease progressi...

The Estrogen Effect Nobody Talks About | Kiran Krishnan

May 05, 2026

Cardiovascular health and longevity are deeply influenced by aging, perimenopause, and systemic changes that extend far beyond cholesterol markers alone. In this episode of New Frontiers in Functional Medicine, Dr. Kara Fitzgerald sits down with Kiran Krishnan to explore the biology of vascular aging, endothelial dysfunction, and metabolic changes that emerge in midlife and beyond. As estrogen declines during perimenopause, patients often experience shifts in lipid metabolism, weight regulat...
