Updated:
The liver processes over 100 gallons of blood daily while performing over 500 vital functions, yet its capacity can be compromised by factors ranging from alcohol consumption to metabolic disorders. Recent clinical studies have demonstrated that specific probiotic strains can modulate liver enzyme levels, reduce inflammation markers, and influence bile acid metabolism through gut-liver axis interactions.
The key challenge lies in identifying and validating probiotic strains that can effectively target specific liver pathways while maintaining stability and viability in the gastrointestinal environment.
This page brings together solutions from recent research—including Lactobacillus strains that reduce hepatic inflammation, bile acid-metabolizing bacteria that prevent cholestasis, targeted probiotics for alcoholic liver disease, and novel bacterial compositions for treating fatty liver conditions. These and other approaches focus on practical therapeutic applications while addressing the complex interactions between gut microbiota and liver health.
