We are conducting a study to see how a probiotic supplement, resB, might help protect gut health and improve recovery in elderly patients with pneumonia. People aged 60 and above, admitted to the ICU, are taking part in this research. These findings suggest that resB may help maintain a healthy balance of good bacteria, reduce harmful ones, and possibly strengthen the body’s defenses — which could help in fighting pneumonia. This is an ongoing study, and these findings are preliminary.
