β-Casomorphin, bovine, is a peptide derived from the digestion of bovine milk proteins, particularly casein. It has been studied for its potential effects on the human body, particularly in relation to its opioid-like activity. This peptide is believed to interact with opioid receptors in the gastrointestinal tract and the central nervous system, which may influence pain perception, mood, and digestive processes. Research has explored its role in conditions such as autism and schizophrenia, though findings remain inconclusive. Additionally, β-casomorphin has been investigated for its potential impact on infant health, as it may be released during the digestion of milk-based formulas. Some studies suggest it could contribute to gastrointestinal discomfort or other adverse effects in sensitive individuals. However, its exact physiological significance and applications in health and medicine are still under active investigation.
