Glucomannan is a natural, water-soluble dietary fiber extracted from the roots of the elephant yam, also known as KONJAC ROOT. Konjac, also known as konjak, konjaku, konnyaku potato, devil’s tongue, voodoo lily, snake palm, or elephant yam, is a plant of the genus Amorphophallus.

Glucomannan has an exceptional ability to absorb water and is one of the most viscous dietary fibers known.

How Does Glucomannan Help with Weight Loss?

Glucomannan has the ability to absorb up to twenty times its own weight in water. It expands after ingestion, takes up space in the stomach and this tends to promote a feeling of fullness and satiety. It also delays emptying the stomach.

Glucomannan is very rich in fiber, so like any other soluble fibers, it reduces the absorption of protein and fat. The ADA recommends that adults should consume at least 20 to 35 grams of fiber each day. The typical American diet provides between 12 and 18 grams. While oat bran, at 14% soluble fiber content, offers the most concentrated sources of soluble fiber among those catalogued by the ADA, glucomannan comprises at least 40% of konjac by dry weight, making konjac the richest source of soluble fiber in nature.

Glucomannan has a very low calorie content.

In addition to promoting weight loss, glucomannan may improve a number of risk factors for heart disease, like reducing the blood cholesterol. It decreases absorption of cholesterol in the gut and reduces the amount of fat present in the blood.

According to studies, adding glucomannan to your diet could also lower the risk of developing type 2 diabetes. It attracts water in the digestive system and becomes a gel, slowing digestive processes and trapping carbohydrates so that blood sugar levels are stabilized. Glucommanan has shown potential to reduce blood glucose, insulin and serum lipid levels after meals, an effect that seems to be enhanced by glucomannans relatively high viscosity compared to other soluble fibers.

Being a water-soluble fiber, glucomannan has also been successfully used to treat constipation. Soluble fiber absorbs water, softens digestive contents and increases stool volume.

IMPORTANTGlucomannan can reduce the absorption of oral medications. This can be avoided by taking the medication at least 4 hours after or one hour before ingesting glucomannan.
