Kristine Bearce, known professionally as KB, is a wellness consultant and the host of the Toxic Free with KB podcast. Drawing on her history as a high-level SoulCycle instructor in New York City, she transitioned into the holistic health space to address environmental toxin exposure and its impact on the endocrine system. She regularly facilitates long-form interviews with medical authorities, such as Dr. Steven Gundry and Dr. William Li, to dissect topics like microbiome health and cellular detoxification protocols. A recent win for her brand includes the successful launch of the 30-Day Reset series, an interactive initiative where she guides participants through comprehensive household audits to eliminate PFAS and heavy metals. Her content features specific product swaps with partners like AirDoctor and AquaTru, focusing on clinical data rather than surface-level trends. By simplifying the science behind leaky gut and nervous system regulation, Bearce provides actionable frameworks for individuals managing autoimmune challenges and chronic inflammation.
