Insights from Martha Carlin on Salad With a Side of Fries
Have you ever wondered why some people stay sharp and active into their 90s, while others struggle with "brain fog" or neurological decline in their 50s?
In a groundbreaking episode of the Salad With a Side of Fries podcast, our founder Martha Carlin joined host Jenn Trepeck to reveal a startling truth: the secret to your brain’s health is actually sitting in your gut.
The 15-Year Warning Sign
Martha shared a insight that every health-conscious person needs to hear: chronic constipation is often the first "alarm bell" for Parkinson's Disease—sometimes ringing 10 to 15 years before a diagnosis. When waste sits in the colon, it creates a "toxic burden" that travels straight to the brain.
How BiotiQuest is Changing the Game
Martha didn't just find a problem; she engineered a solution. During the interview, she explained the science behind BiotiQuest and our flagship formula, Sugar Shift®.
- The Goal: To turn your gut into a "production factory" for mannitol, a natural sugar alcohol that helps prevent protein clumping in the brain.
- The Result: Precision microbiome engineering that doesn't just "add bacteria" but actively repairs your internal engine.
Martha’s "Citizen Scientist" Tip
One of the most powerful moments in the episode was Martha’s reminder that we are not helpless. By shifting our microbiome with functional consortia and avoiding "microbiome disruptors" like glyphosate and harsh cleaners, we can change our health trajectory.
“If you change the soil, you change the plant,” Martha told Jenn. “If you change the microbiome, you change the human.”

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.
