Metabolic Freedom With Ben Azadi #1220 Microplastics Are Wrecking Your Metabolism - The Shocking Detox Science You Need to Know with David Roberts and Dr. John Gildea
What if the biggest metabolism disruptor today is not carbs or calories, but the toxic load you cannot see?
In this episode of the Metabolic Freedom Podcast, Ben Azadi sits down with Mara Labs co-founders David Roberts and Dr. John Gildea for a deep dive into microplastics, detox pathways, and the science of sulforaphane. They break down how microplastics and the chemicals that leach from plastics can interfere with cellular function, including lysosomes, autophagy, inflammation, and hormone signaling. You will learn why sulforaphane is known for activating Nrf2, what that means for detox and repair genes, and why the conversation around metabolic health is also a conversation about toxin exposure.
They also discuss berberine as a tool for metabolic flexibility, blood sugar support, ketosis, and even sleep, plus new product innovations like BarkElite for dogs.
If you want practical strategies backed by research and real-world testing, this one is packed.
