Immune Health Products

With over 70% of the immune system residing in the digestive tract, our gut is the first line of defense against potentially harmful pathogens and is closely related to overall health. Our daily diet directly affects gut health and therefore immune function. Accordingly the demand for dietary ways to support immunity has only been growing. This is why IFF offers a full range of immune health probiotic options perfected for every stage of life.
