In this eye-opening episode, David Avocado Wolfe sits down with microbiome researcher, entrepreneur, and BiotiQuest Founder Martha Carlin to explore the fascinating connections between gut health, Parkinson’s disease, aging, environmental toxins, and human resilience. What began as Martha’s search for answers after her husband’s Parkinson’s diagnosis evolved into years of groundbreaking research into the trillions of microbes that influence every aspect of our health.

Together, David and Martha discuss how environmental exposures can alter the microbiome, why certain beneficial bacteria may hold the key to better health, and how emerging microbiome science could reshape the future of medicine.

Martha Carlin photo Martha Carlin, is a “Citizen Scientist”, systems thinker, wife of Parkinson’s warrior, John Carlin, and founder of The BioCollective , a microbiome company expanding the reach of science and BiotiQuest, the first of it’s kind probiotic line. Since John’s diagnosis in 2002, Martha began learning the science of agriculture, nutrition, environment, infectious disease, Parkinson’s pathology and much more. In 2014, when the first research was published showing a connection between the gut bacteria and the two phenotypes of Parkinson’s, Martha quit her former career as a business turnaround expert and founded The BioCollective to accelerate the discovery of the impact of gut health on all human disease. Martha was a speaker at the White House 2016 Microbiome Initiative launch, challenging the scientific community to “think in a broader context”. Her systems thinking background and experience has led to collaborations across the scientific spectrum from neuroscience to engineering to infectious disease. She is a respected out of the box problem solver in the microbiome field and brings a unique perspective to helping others understand the connections from the soil to the food to our guts and our brains.
