Colostrum, the first milk produced by mammals after giving birth, is rich in immunoglobulins, growth factors, and antimicrobial peptides. Scientific evidence suggests that bovine colostrum supplementation may support the health and function of the small intestine, particularly by enhancing gut barrier function and modulating immune responses. Several studies have demonstrated that colostrum can help reduce intestinal permeability (“leaky gut”) and protect against gastrointestinal challenges, such as infections and inflammation. For instance, research published in Clinical Nutrition (2010) and Gut (1999) showed that colostrum supplementation reduced intestinal permeability in athletes and patients taking non-steroidal anti-inflammatory drugs (NSAIDs). Additionally, colostrum appears to have beneficial effects in conditions such as infectious diarrhea and inflammatory bowel disease, though findings are mixed and often based on small or preliminary trials. The growth factors in colostrum, such as IGF-1 and TGF-β, are believed to promote repair and maintenance of the intestinal lining. While further large-scale, high-quality clinical trials are needed to firmly establish its efficacy, current scientific evidence does support a role for colostrum in supporting small intestine health, especially in situations of increased gut permeability or stress.
