Psyllium: Uses & Side Effects

Psyllium (Metamucil) is a bulk-forming fiber laxative. It works by absorbing liquid and swelling in the intestines to create a softer, bulky stool that is easier to pass. Psyllium is used to treat occasional constipation or bowel irregularity. Psyllium may also help lower cholesterol when used together with a diet low in cholesterol and saturated fat.
