the Role of Probiotic in Protein Metabolism

Assessing the Impact of Weizmannella Coagulans BC99 on Protein Digestion and Metabolism: A Randomized, Double-Blind Controlled Trial

This study investigates the functional effects of probiotics on athletes by administering Weizmannella coagulans BC99 for 12 weeks. It aims to assess the probiotic's influence on skeletal muscle content, athletic performance, and protein digestion and metabolism. This is achieved by monitoring changes in digestive enzymes, amino acids, body composition, and hormone levels. The research seeks to offer a theoretical foundation for optimizing athletes' training and nutrition strategies and suggests the potential of probiotics in enhancing nutrient absorption and utilization, particularly in individuals with compromised digestive capabilities.
