A new study reveals how a common dietary supplement may significantly alter gut bacteria in ways that could impact long-term health. Researchers found that regular consumption of the supplement led to measurable changes in microbial diversity, with potential effects on metabolism and immune function. The findings suggest a previously understudied connection between dietary additives and gut microbiome composition, raising questions about broader implications for public health. Experts caution that more research is needed before definitive conclusions can be drawn.
