What is psyllium?
Psyllium is a bulk-forming fiber laxative. Psyllium works by absorbing liquid in the intestines and
swelling to create a softer, bulky stool that is easier to pass.
Psyllium is used to treat occasional constipation or bowel irregularity. Psyllium may also be used
to treat diarrhea and may help lower cholesterol when used together with a diet low in cholesterol and
saturated fat.
Psyllium may also be used for other purposes not listed in this product guide.
What should I discuss with my healthcare provider before taking psyllium?

What should I avoid while taking psyllium?
