Konjac Extract Fiber is one of Trimoryn's six named ingredients, standardized to 90% glucomannan. Here's what that actually is.
Glucomannan is a water-soluble fiber extracted from the root of the konjac plant, long used in East Asian cuisine and, more recently, in weight-support supplements.
Glucomannan absorbs water and expands significantly in the stomach, which is thought to support feelings of fullness before a meal.
Glucomannan is one of the few fiber ingredients with a meaningful body of research behind its use in appetite and weight support — most weight-support supplements don't include it at all.
Take it with plenty of water as directed, since a fiber that expands needs adequate fluid to work as intended and to be taken comfortably.
