Colostrum protein, particularly bovine colostrum, is supported by scientific evidence for its role in supporting small intestine health. Colostrum is the first milk produced by mammals after birth and is rich in immunoglobulins (antibodies), growth factors, and antimicrobial peptides. Several clinical studies have investigated the use of bovine colostrum supplements in humans for gastrointestinal health, particularly for protecting and repairing the intestinal lining.

Studies have shown that colostrum can help reduce intestinal permeability, commonly referred to as "leaky gut," and may protect against damage from non-steroidal anti-inflammatory drugs (NSAIDs) (Playford et al., 2001). Additionally, colostrum supplementation has been studied in athletes and individuals experiencing increased gut permeability due to intense exercise, with results suggesting improved gut barrier function (Davison & Diment, 2010).

The bioactive components in colostrum, such as lactoferrin and growth factors (IGF-1), are believed to promote the growth and repair of intestinal tissues and modulate immune responses. Although most studies are small and more large-scale clinical trials are needed, the existing evidence supports the use of colostrum protein for small intestine support, especially in the context of gut barrier integrity and repair.
