Gut health is a complex and fascinating field, increasingly recognized as deeply interconnected with our nervous system, emotional well-being, and even chronic diseases like Parkinson’s. In a compelling episode of the Make Peace with Food podcast, host Sherry Shabban sits down with Martha Carlin, founder of The BioCollective, to explore how unresolved trauma and stress can disrupt gut health and how innovative probiotic solutions are emerging to address these challenges.
The Gut-Brain-Trauma Connection
Martha’s journey into gut health science began with a personal crisis: her husband John’s Parkinson’s diagnosis at just 44 years old. This unexpected diagnosis propelled her to question conventional medical narratives and seek deeper answers. She discovered that a dysregulated nervous system, often rooted in early trauma or chronic stress, can set the stage for major gut disruption, commonly known as dysbiosis or leaky gut.
“Your gut is your internal pharmacy—if it’s out of balance, every system in your body feels it,” Martha explains. This internal ecosystem, the microbiome, is profoundly affected not only by diet but also by emotional stress and toxic exposures accumulated over a lifetime.
Trauma’s Hidden Impact on the Microbiome
Through interviews and research, Martha uncovered a striking pattern: many people with Parkinson’s had experienced significant unresolved trauma or loss prior to their diagnosis. These emotional wounds, often unaddressed due to generational stigma around discussing feelings, can silently disrupt the microbiome and nervous system balance.
One poignant insight from Martha’s work is the importance of addressing these psychological and emotional roots alongside biological treatments. “It’s never too late to do this work,” she emphasizes, sharing stories of clients in their 70s healing childhood traumas and seeing improvements in their health and quality of life.
Food, Environment, and Bioindividuality
Martha highlights the critical role of diet in gut health but cautions against one-size-fits-all approaches. Whether plant-based, carnivore, or ketogenic, the best diet depends on the individual’s unique microbiome and their body’s ability to detoxify environmental chemicals like pesticides and herbicides.
She notes, “The total toxic burden of what’s in your food is part of that missing connection,” urging awareness of chemical exposures that disrupt gut lining and nutrient absorption.
Innovative Probiotic “Microbial Teams”
Breaking from traditional probiotic supplements that often contain single strains, Martha and her team developed a revolutionary approach: probiotic blends designed as “microbial teams.” These teams work synergistically to restore the gut’s internal pharmacy and repair gut-brain communication.
Using computational models, they design specific microbial communities targeted for outcomes like improved sugar metabolism, immune support, better sleep, and cardiovascular health. For example, their “Sugar Shift” probiotic helped Martha’s husband reduce Parkinson’s symptoms and sugar cravings by producing mannitol, a free radical scavenger.
Clinical trials showed promising results, including improved insulin sensitivity and reduced inflammatory endotoxins linked to chronic diseases.
Managing Stress and Nervous System Regulation
The conversation also delves into the importance of nervous system regulation. Stress and trauma can exacerbate gut issues, but resilience—the ability to return to a parasympathetic (rest-and-digest) state—is key. Martha shares how modifying her own behavior to reduce household stress positively impacted her husband’s health.
Final Thoughts
Martha Carlin’s work is a powerful reminder that true healing requires a holistic approach—addressing not just the gut, but also the mind and heart. Her innovative probiotic formulations and emphasis on emotional healing offer hope for those struggling with chronic gut issues and neurological conditions.

Quotes from Martha Carlin:
“Your gut is your internal pharmacy—if it’s out of balance, every system in your body feels it.”
“We move towards what we see. If you can present a different picture, it’s very powerful.”
“The total toxic burden of what’s in your food is part of that missing connection.”

With gratitude,
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.
