The digestive system is your body's first line of defense against unwanted organisms consumed with food. An important component of your digestive defense system is a variety of friendly bacteria that aid digestion and enhance your body's own digestive immune response. As we encounter challenges to our digestive system we can severely disturb the delicate balance of our body's intestinal flora which can cause occasional gastrointestinal (GI) discomfort, bowel irregularity, occasional diarrhea, and other digestive and non-digestive discomforts. Fortunately, a healthy balance of intestinal flora can be restored through the consumption of food or food supplement products that contain friendly live bacteria cultures commonly referred to as probiotics.
