BiotiQuest® Gut Health & Probiotics Blog with Martha Carlin

Improve Gut Health to Protect Your Brain, Metabolism & Longevity | Martha Carlin

Martha Carlin | Jan 06, 2026 | podcast

Martha Carlin explains how the microbiome, endotoxin, & the glycocalyx influence energy, cognition, and long-term resilience & why gut repair is central to protecting longevity.

Key takeaways

  • Be mindful of everything you eat & drink Your body reflects daily choices
  • The modern food supply including chemicals & engineering drives or disrupts long-term wellness
  • Your gut microbiome influences nearly every aspect of health, not just digestion
  • Gut bacteria differences correlate with neurological disease profiles such as Parkinson’s
  • Stool analysis reveals more health data than most expect Investigate output for internal clues
  • Genetic material from food & microbes transfers into the body, influencing health in unexpected ways
  • Single-strain probiotics fall short Full microbial teams support stronger gut ecosystems & outcomes
  • Household chemicals damage the gut lining Auditing cleaning products protects barrier health
  • Gut health depends on balance & relationships, not just which organisms exist
  • Quality water & whole foods are the strongest foundational longevity levers—start there

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.
