Fiber supplements provide a number of benefits and can be found in many fruits and vegetables. Most people do not get enough dietary fiber, so to promote digestive health, a fiber supplement can help. Fiber functions in multiple ways in the digestive tract. For one, it helps to maintain a healthy intestine. A healthy intestine allows the body to properly digest. It also supports colon health by making sure that food continues to move through the digestive system, and lessens constipation. For several disorders, including irritable bowel syndrome, a daily fiber supplement is highly recommended. Fiber also contributes to health in the immune system, the bones, the heart, and promotes weight loss. Further, long-term daily use of fiber has been shown to have no harmful side effects.
