Chr. Hansen Launches Largest Probiotic Immune Study

Chr. Hansen’s probiotic portfolio is already among the best scientifically documented in the world, and very recently an immune study with remarkable findings was published in the British Journal of Nutrition.

Oct 4 2011 --- Chr. Hansen now launches the largest probiotic immune study of its kind to further substantiate the scientific documentation behind its probiotic strains. Ultimately, the objective is to prove that consuming probiotics will help people protect themselves against influenza and common cold.

Influenza and other viral respiratory tract infections (VRTI) such as the common cold affect a vast number of people every year, representing a significant societal health issue with massive economic costs.

In the US alone, approx. 500 million non-influenza-related VRTI episodes occur per year. The total economic impact of treating these infections approaches $40 billion annually. Further, the annual influenza epidemics in the US result in an average of direct medical costs of $10.4 billion annually, and the total economic burden of annual influenza epidemics amount to $87.1 billion.

Using an influenza vaccination model, Chr. Hansen’s new study involving 1058 healthy adult participants will investigate how the consumption of ‘L. casei 431’ one of Chr. Hansen’s flagship probiotic strains will support healthy people’s immune system in fighting off viral respiratory tract infections.

“Chr. Hansen’s probiotic portfolio is already among the best scientifically documented in the world, and very recently an immune study with remarkable findings was published in the British Journal of Nutrition. The study which we are now initiating will significantly improve the scientific evidence of the immune health benefits of our probiotics in healthy people,” says Chr. Hansen’s Birgit Michelsen, Director of Scientific Affairs, Health & Nutrition Division. “The study stands out by being very large, by involving healthy people, and by taking advantage of using the same standards and quality tools as pharmaceutical studies.”

The study is conducted in collaboration with the Department of Human Nutrition, Faculty of Life Sciences, University of Copenhagen, Denmark, and the Harrison Clinical Research in Munich, Germany, a contract research organization. Professor Lars O. Dragsted who heads up the University of Copenhagen’s research team involved in the study, says: “We are exceptionally pleased and proud to be collaborating with Chr. Hansen on this prestigious study. Carrying this unusually large and ambitious study through requires clinical excellence and we expect it to add significant new evidence to the research area and also benefit the University of Copenhagen as a trusted and competent academic partner.”
