Vitamin D Study Hour with GrassrootsHealth: Vitamin D, Insulin Resistance & Type 2 Diabetes Featuring Dr. Barbara Boucher
Dr. Barbara Boucher, an internationally respected physician-scientist and Honorary Professor of Metabolic Medicine, explores the growing body of evidence linking vitamin D deficiency to insulin resistance, metabolic syndrome, prediabetes, and type 2 diabetes. Drawing on decades of clinical experience and large population studies, Dr. Boucher explains how vitamin D influences insulin secretion, insulin sensitivity, and metabolic health across the lifespan.
In this presentation and Q&A, Dr. Boucher highlights why low vitamin D status is consistently associated with greater insulin resistance and metabolic dysfunction, and why correcting deficiency may be especially important during early stages such as prediabetes, when beta-cell function is still preserved. She discusses how improving vitamin D status may help reduce progression to type 2 diabetes when combined with broader lifestyle and clinical strategies.
This talk underscores the importance of measuring vitamin D levels, identifying deficiency, and viewing vitamin D sufficiency as a foundational component of metabolic health and diabetes prevention, particularly in high-risk populations.
