Is it normal to have rubber like jelly in the stool when taking Metamucil?

Medically reviewed by Last updated on Oct 26, 2023.

When I have a bowel movement my stool is made up of a substance that resembles tough rubberized jelly. It is sometimes difficult to pass this. It seems as though once it gets into my stomach it becomes a jelly like substance and my stomach does not digest this.

Official answer


Yes, Metamucil can cause you to have a jelly like stool.
Metamucil (psyllium) Psyllium is a bulk-forming fiber laxative. It 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.
