Dannon probiotic yogurt contains beneficial bacteria like Bifidobacterium lactis that can aid digestion when consumed daily. These probiotics survive the gastrointestinal system and establish themselves in the intestines to provide effects like supporting the immune system and digestive health. Dannon yogurt provides over 1 billion live, active strains of B. lactis per serving along with Lactobacillus bulgaricus and Streptococcus thermophilus. It works by delivering probiotics to the intestines alive where they can confer benefits. Probiotics from food provide nutrients not found in supplements, though supplements contain higher bacteria counts. Both sources can be beneficial when combined with a balanced diet and lifestyle.
