There are many benefits to taking probiotics, including preventing constipation. Probiotics can help to maintain a healthy balance of bacteria in the gut by producing substances which inhibit harmful bacteria from growing. They also produce substances that stimulate the growth of helpful bacteria, so they can quickly take up residence when someone is sick or has taken antibiotics for example. This means less chance for bad things to happen - like clostridia infections- and more chance for good things- like maintaining a healthy pH level within your intestines!
