Summary

This study looked at whether a probiotic called Weizmannella coagulans BC99 can help athletes digest protein and build muscle. 72 healthy adults took the probiotic for 12 weeks. Researchers measured changes in digestion, amino acids, body composition, and hormone levels to see if the probiotic improves nutrient absorption and athletic performance.
