The gut microbiome's influence on cardiovascular health involves complex metabolic and immune pathways. Clinical studies have shown that specific bacterial strains can modulate cholesterol metabolism, reduce inflammatory markers like CRP and IL-6, and help maintain healthy blood pressure levels through multiple mechanisms including the metabolism of dietary compounds and production of bioactive metabolites.

The key challenge lies in identifying and validating specific probiotic strains that can effectively influence cardiovascular biomarkers while maintaining viable populations in the dynamic gut environment.

This page brings together solutions from recent research—including targeted use of Lactobacillus and Bifidobacterium strains for blood pressure regulation, engineered microbes for cholesterol metabolism, and novel bacterial combinations that strengthen intestinal barrier function. These and other approaches focus on translating microbiome science into practical therapeutic strategies for cardiovascular health.
