Sleep, Clarity, Immunity: Start With Your Microbiome - Martha Carlin
by Kevin Danielson August 19, 2025
In this episode of Vitality Made Simple, Martha Carlin, founder of BiotiQuest, joins us to discuss the critical role the gut microbiome plays in our health and how her probiotic formulations are designed to work in harmony—much like a thriving ecosystem. She explains the science behind consortia probiotics, where multiple strains support each other’s growth, producing benefits that extend far beyond digestion. From the BiotiQuest Sugar Shift blend for metabolic health to the BiotiQuest Antibiotic Antidote Probiotics for post-antibiotic recovery, she shares how her products address the interconnected systems of the body.
In a recent interview, Chris Wark spoke with Martha Carlin—author of Connected: Love Loss and the Unseen Forces Behind Chronic Disease, microbiome researcher, and founder of BiotiQuest—about her 24-year journey investigating the root causes of neurodegenerative and metabolic diseases.
At the end of August, I flew from Kentucky to Australia for three weeks. By the time I arrived in Canberra, I had crossed the International Date Line, lost an entire day, and completely flipped my normal schedule. I did what I could to prepare. I fasted before the flight, took my Simple Slumber and another herbal sleep supplement, and managed to get some sleep on the overnight flight. Even so, I arrived expecting my body to have absolutely no idea what time it was. What surprised me was how quickly it began to figure it out.
Behind closed eyes, the brain is carrying out a carefully coordinated night shift. And research into the microbiome raises an intriguing question: how might the activity in our gut influence the sleep that gives this work its opportunity?
