In a compelling episode of The Kick Sugar Coach podcast, Martha Carlin, founder of BiotiQuest and a pioneering microbiome scientist, shares her journey and groundbreaking research on how gut bacteria influence nearly every system in our body. Her work, inspired by her late husband John’s Parkinson’s diagnosis, has led to innovative probiotic formulations that support gut health, reduce sugar cravings, and improve metabolic function.
The Microbiome: Our Internal Pharmacy
Martha emphasizes the microbiome’s critical role as “your primary factory for hormones, neurotransmitters, and vitamins.” She explains:
“It’s making most of your serotonin... key amino acids like tyrosine, tryptophan, and phenylalanine... dopamine and melatonin... It’s involved in training your immune system and metabolizing medicine.”
This intricate ecosystem of trillions of microbes is essential for overall health, and damage to it can lead to inflammation, mood swings, hormone imbalances, and blood sugar issues.
Major Disruptors of Gut Health
Martha highlights several factors that disrupt the microbiome, including:
- Antibiotics: Often overused from birth, they indiscriminately kill beneficial bacteria.
- Birth Method and Infant Feeding: Cesarean births and lack of breastfeeding can impair initial microbial colonization.
- Surfactants and Chemicals: Found in soaps, shampoos, and cleaning products, these can suppress immune function and damage gut lining.
- Sugar and Glyphosate: Sugar feeds pathogenic bacteria, while glyphosate (a common herbicide) acts as an antibiotic, harming both soil and gut microbiomes.
Sugar Shift®: A Targeted Probiotic Solution
One of Martha’s signature products, Sugar Shift®, is designed to help rebalance the gut microbiome by converting harmful sugars into mannitol, a sugar alcohol that feeds beneficial bacteria but starves pathogenic strains. Martha shares:
“By removing glucose and fructose and putting in mannitol, which feeds the good bacteria but starves the bad bacteria, you start to gradually get this change in the overall microbiome.”
Clinical trials demonstrated that Sugar Shift® significantly reduced endotoxin-producing bacteria and inflammation markers, while increasing keystone species like bifidobacteria. Remarkably, one user reported:
“After taking Sugar Shift for a year, his A1C dropped four points without changing diet or medications.”
Martha stresses that while some see rapid results, for most people, it’s a gradual process akin to a “marriage” with their microbiome.
Perfect Peace: Supporting Calm and Stress Relief
Martha also introduced Perfect Peace, a probiotic formula aimed at restoring GABA, the body’s calming neurotransmitter. She recounts her personal experience:
“During a stressful 36-hour trip, I took Perfect Peace and felt incredibly calm despite the chaos. My team notices a change in my demeanor within 15-20 minutes of taking it.”
Beyond Pills: Innovative Uses and Future Directions
Martha encourages exploring diverse ways to incorporate probiotics, such as using Sugar Shift® as a starter culture for homemade yogurt or fermented drinks. She also mentions other specialized products like Antibiotic Antidote and Ideal Immunity for gut reset and pathogen defense.
Final Thoughts
Martha Carlin’s work underscores the profound impact of the microbiome on health and the potential of targeted probiotics to repair and restore balance. Her journey from personal tragedy to scientific innovation offers hope and practical tools for anyone looking to improve gut health, reduce sugar cravings, and enhance overall well-being.

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.
