One course of antibiotics has the power to wipe out certain strains from your microbiome forever. Like everything in health, it’s all about dose and right use, but when it comes to antibiotics we are reaching for it too causally without grappling with the real-world consequences. Unfortunately, Martha Carlin was unable to ignore them when it impacted her family in the most fundamental of ways. She has since become a master of gut health, and is serving the public and fight against chronic disease with offerings of the highest quality gut medicine possible. 

Martha Carlin is a systems thinker, entrepreneur, and founder of The BioCollective, whose journey began when her husband John was diagnosed with Parkinson’s disease at age 44. Refusing to accept a future of inevitable decline, she applied her expertise in corporate turnarounds to uncover new approaches to managing and potentially altering the course of chronic disease. Her research  led her to recognize the central role of the gut, which she describes as the “general ledger” of health. In 2014, emerging science confirmed her insights, sparking her to leave her career and begin funding microbiome research at the University of Chicago with Dr. Jack Gilbert.
