Improves gut health
Berberine is tricky for the body to absorb, allowing a good portion of it to reach the colon intact, where it influences the gut microbiome. By interacting with gut bacteria, berberine promotes the growth of healthy bacteria and enzymes needed to synthesize critical metabolites, including branched-chain amino acids (BCAAs) and components of brain-friendly dopamine. Berberine also strengthens the intestinal barrier, which plays a central role in immunity and metabolic health.
