The Active Ingredient Is: Glucomannan

Glucomannan is a soluble fibre sourced from the Konjac plant that contributes to a fibre-rich diet and normal digestive function. This ingredient is included as part of a multi-source soluble fibre blend to support gentle bulk in the gut.

This form is derived from the Konjac root and is used to help absorb water and swell, supporting a comfortable, regular digestion process as part of a balanced diet.

What Does Glucomannan Do?

Glucomannan participates in normal gut function by absorbing water and forming a gel-like substance in the digestive tract, which can help support regularity and fullness after meals in line with EFSA guidance.

Scientific research suggests soluble fibres like glucomannan can influence digestion and satiety, contributing to daily fibre intake and gut comfort according to NHS and EFSA principles.
