How gut decongestion works
I-O combines insoluble fibers with mineral adsorbents and vitamin C in a simple, daily ritual. The synergy is designed to help sweep, bind, and support—without stimulants or added sugars.
Cellulose + oat fibers act like a gentle brush to support regularity and help move things along.
Minerals (diatomaceous earth + calcium silicate) have high surface area—designed to bind and carry out unwanted buildup.
Vitamin C provides antioxidant support; sunflower lecithin helps emulsify fats—supporting a comfortable, balanced gut environment.
