Gut bacteria may be key to heart health, new study suggests

This study tests whether a probiotic called Limosilactobacillus fermentum CRL 1446 can improve health in 80 adults with heart disease risk factors like obesity, high blood pressure, and high cholesterol. Participants take either the probiotic or a placebo daily, and researchers measure effects on blood sugar, body composition, inflammation, and stress. The goal is to see if this friendly bacterium can help prevent or manage chronic heart conditions.
