With calcium butyrate as the core active ingredient, it combines the dual functions of intestinal maintenance and mineral supplementation. Upon reaching the intestine, it gradually releases butyric acid and calcium ions, directly providing energy to intestinal epithelial cells, promoting villus development and mucosal barrier repair, optimizing the gut microbiota structure, inhibiting harmful bacteria, and alleviating inflammation. At the same time, it can supplement minerals to support skeletal development.
