Fibosyl is a natural, bulk-forming laxative formulated with Psyllium (Ispaghula) Husk, derived from the seeds of Plantago ovata. It contains approximately 70% soluble and 30% insoluble fibers, capable of absorbing up to 40 times its weight in water. This property allows it to swell in the bowel, increasing stool bulk and promoting regular bowel movements.
