About Psyllium

Whole Psyllium Husk Powder is a natural, water-soluble fiber derived from the seed husks of the Plantago ovata plant. It consists primarily of hemicellulose, a polysaccharide that forms a viscous gel when mixed with water. This gel-forming property is responsible for its primary physiological effects as a bulk-forming laxative and stool softener. The 'whole' designation indicates minimal processing, retaining the natural husk structure. It is classified as a dietary fiber supplement and is widely used for gastrointestinal health, cholesterol management, and blood sugar regulation.
