Konsyl is the #1 doctor-recommended all natural psyllium fiber supplement. Konsyl Original and Konsyl Easy Mix psyllium fiber products are all natural, gluten-free and contain no sugar or sugar substitutes. They are safe for celiac patients, diabetics and pregnant and nursing mothers. Dr. Paul Senter, MD of Colon & Rectal Surgery in Fort Worth, Texas says: Konsyl is the best source of natural bulk fiber on the market today. Konsyl is pure psyllium which allows the highest dietary fiber per dose. His patients prefer Konsyl over many other bulk-forming laxatives because post surgically, Konsyl provides them with the easiest elimination.
