Thank you for leaving your review, and we understand how important it is to have a healthy digestive system. Our Align Digestive Probiotic Supplement contains Bifidobacterium longum 35624, a ‘friendly’ bacteria, which helps to promote and maintain a natural, healthy digestive system. These friendly bacteria provide a natural defense against common digestive upsets. Align has been developed for a wide range of people who experience digestive problems, and everybody’s digestive system adjusts slightly differently. Most people begin to notice differences in their digestive health in the first few weeks. We recommend that you take Align as part of your daily routine, at a time of day that will be easy to remember. If at any time you are concerned about how your body is responding to this product, we recommend visiting your doctor. Your feedback is important to us, and we’d love to learn more. So please give us a call at (800) 208-0112.
