Psyllium is a form of fiber made from the husks of the Plantago ovata plant’s seeds. It sometimes goes by the name Ispaghula or Isabgol. 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.
Psyllium is mainly used as a dietary fiber to relieve symptoms of both constipation and mild diarrhea, and occasionally as a food thickener. It is commonly used as a food ingredient in manufactured breakfast cereals which may contribute to a healthy lifestyle by improving blood cholesterol levels and gastrointestinal function.
