Psyllium Husk
Also known as Ispaghula, Plantago ovata, Psyllium fiber
Psyllium husk is a soluble, gel-forming fiber from the seeds of Plantago ovata. It absorbs water to form a gel that softens stool, eases both constipation and diarrhea, and slows digestion. It has strong evidence for improving regularity, lowering LDL cholesterol, and blunting post-meal blood sugar.

StrongDaily psyllium reliably reduces LDL and total cholesterol by binding bile acids, an effect recognized by health authorities.
