Morinaga Milk Industry has announced the results of a summary of clinical trial results for virus-infectious gastroenteritis including norovirus caused by lactoferrin intake and basic research results on the elucidation of the mechanism. According to this, it was suggested that lactoferrin intake leads to suppression of virus-infectious gastroenteritis such as norovirus and relief of symptoms.

Lactoferrin is a protein contained in the milk and saliva of mammals such as humans. It is known to exhibit various physiological functions such as antimicrobial activity and immunomodulatory action. Among them, it is abundant in breast milk, especially in the first milk, and protects babies with weak resistance from infection by pathogens and viruses. It is considered an important ingredient.

In the discussion of the summary of this report, lactoferrin is infectious by binding to the surface of viruses such as norovirus and rotavirus and the gastrointestinal cells that are the sites of infection, and suppressing the infection of the virus to the gastrointestinal cells. It is said that it is possible that the onset of gastroenteritis was suppressed and the symptoms were alleviated.
