The Active Ingredient Is: Glucomannan (Konjac Root)

Glucomannan is basically a water-soluble fibre sourced from konjac root, acting as a bulking fibre in the gut. This fibre is mainly recognised for its pure konjac root make-up in this product.

This form is sourced from konjac root and sold as a single-ingredient fibre supplement to help support dietary fibre intake as part of a balanced diet.

What Does Glucomannan Do?

Glucomannan helps with satiety by absorbing water and forming a bulky gel in the stomach, which helps keep you feeling full and supports normal digestion. It also helps slow gastric emptying and may influence the rate of glucose and cholesterol absorption in the gut, while acting as a prebiotic to support gut health.

Additionally, this fibre helps support normal bowel function through its bulking action, contributing to regularity as part of a fibre-rich diet.
