Fiver helps to promote bowel movement and holds water in the bowel which is why it can be used as a prevention and treatment for constipation. It is also used in cases of loose stools to provide more bulk and substance which helps to regulate bowel motions also. Many soluble fibers also help to promote bowel health and regulate gut bacteria so it really is an essential and often forgotten dietary component
