Episode 117: How Hidden Toxins & Gut Health Impact Chronic Disease with Martha Carlin
What if chronic illness, inflammation, anxiety, neurodegeneration, and nervous system dysregulation were all connected through one powerful system in the body — the microbiome?
In Episode 117 of the Mind Body Detox Podcast, Kara Lovehart sits down with microbiome researcher and BiotiQuest founder Martha Carlin for a fascinating conversation about the hidden links between environmental toxins, stress, gut health, Parkinson’s disease, and chronic illness.
Martha’s journey into microbiome science began after her husband was diagnosed with Parkinson’s disease at just 44 years old. Frustrated by a medical system that offered few answers beyond symptom management, she began investigating the deeper root causes of chronic illness through a systems-based lens — eventually becoming a leading voice in microbiome research and environmental health.
Together, Kara and Martha explore how everything from glyphosate and mold toxins to chronic stress and nervous system dysregulation can influence the gut-brain connection and long-term health outcomes.
What You’ll Learn
In this episode, you’ll discover:
- How the microbiome influences chronic disease and inflammation
- The connection between constipation, detoxification, and toxic burden
- Why environmental toxins may disrupt gut health and nervous system regulation
- How stress and trauma impact the gut-brain axis
- The surprising relationship between Parkinson’s disease and the microbiome
- Why glyphosate and household chemicals may affect beneficial bacteria
- How detox pathways support healing and resilience
- The role of probiotics, fermented foods, and lifestyle shifts in restoring gut health
This conversation blends cutting-edge science with practical wellness insights, helping listeners understand the bigger picture of healing through a mind-body systems approach.
About Our Guest
Martha Carlin is a pioneering citizen scientist, systems thinker, and founder of BiotiQuest and The BioCollective. After her husband’s Parkinson’s diagnosis, she left a successful corporate career to investigate the deeper connections between the microbiome, metabolism, environmental toxins, and chronic disease.
Her work focuses on restoring microbial balance through research-backed probiotic formulations and systems-based wellness strategies that bridge science, detoxification, and holistic healing.

Key Insights & Takeaways
Everything Is Connected
One of the strongest themes throughout this episode is the reminder that the body does not function in isolated systems.
The gut, brain, nervous system, immune system, emotional health, and environmental exposures all interact continuously. Martha explains how modern medicine often separates symptoms into categories, while many chronic illnesses may actually share common root imbalances within the microbiome and detoxification systems.
This systems-based perspective is central to understanding chronic health challenges more deeply.
The Gut-Brain Connection Is Real
The microbiome plays a major role in neurotransmitter production, nervous system regulation, mood, and inflammation.
Martha discusses how certain bacteria can influence stress hormones, serotonin pathways, GABA production, and inflammatory processes that affect both physical and mental health.
This helps explain why gut imbalances may contribute to symptoms like:
- Anxiety
- Depression
- Brain fog
- Fatigue
- ADHD symptoms
- Nervous system dysregulation
- Chronic inflammation
Kara also shares parts of her own detox and healing journey involving lead toxicity, microbiome disruption, nervous system overload, and sensory sensitivity.
Environmental Toxins & Chronic Disease
The conversation also dives into how toxins may influence the microbiome and overall health.
Topics discussed include:
- Glyphosate
- Mold toxins
- Heavy metals
- Mercury exposure
- Household chemicals
- Water contamination
- Dry cleaning chemicals
- Chronic toxic burden
Martha explains how toxins can disrupt beneficial bacteria, impair detoxification pathways, and contribute to inflammatory conditions over time.
She also highlights the importance of supporting elimination pathways, including healthy bowel movements, hydration, minerals, sweating, and nervous system regulation.
Healing Is Possible
Despite the complexity of chronic illness, this episode carries a deeply hopeful message.
Healing does not happen all at once. It happens layer by layer through awareness, support, nervous system safety, and gradual lifestyle changes.
Martha emphasizes that microbes are not the enemy — many are powerful allies that help support detoxification, nutrient production, immune health, and resilience.

FAQ
What is the microbiome?
The microbiome refers to the trillions of bacteria, fungi, viruses, and microorganisms that live in and on the human body, especially within the gut.
Can gut health affect mental health?
Yes. Research continues to show strong connections between the gut-brain axis, neurotransmitter production, inflammation, and emotional well-being.
What environmental toxins were discussed in this episode?
The episode discusses glyphosate, mold toxins, heavy metals, mercury, dry cleaning chemicals, household cleaners, and water contaminants.
Why is constipation important for detoxification?
Regular bowel movements help remove waste and toxins from the body. Impaired elimination may contribute to toxic burden and inflammation.
Can probiotics help support the microbiome?
Certain probiotic strains may help restore microbial balance, support digestion, immune health, and nervous system regulation.
