Psyllium is a type of fiber commonly used as a gentle, bulk-forming laxative.
Being a soluble fiber, psyllium is able to pass through your digestive system without being completely broken down or absorbed.
This article tells you all you need to know about psyllium, including 7 ways it can benefit your health.
Psyllium is a soluble fiber derived from the seeds of Plantago ovata, an herb mainly grown in India (1).
It’s used as a dietary supplement and is usually found in the form of husk, granules, capsules or powder. However, it can also be obtained through fortified breakfast cereals and baked goods (2).
Psyllium husk is the main active ingredient in Metamucil, a fiber supplement often used to reduce constipation.
Because of its excellent water solubility, psyllium can absorb water and become a thick, viscous compound that resists digestion in the small intestine.
Moreover, unlike some other potent sources of fiber, psyllium is well tolerated (4).
