Supplement Description

Glucomannan is a natural, water-soluble dietary fiber extracted from the roots of the elephant yam, also known as konjac.

Clinically proven to support weight loss

Glucomannan has been proven to contribute to weight-loss as part of an energy-restricted diet.

It is approved by the European Food Safety Authority (EFSA) as a proven and safe supplement to aid weight loss and lower cholesterol levels, when taken as part of a calorie controlled diet. The bulk-forming fibre absorbs water in the stomach and it is believed to promote weight loss via several mechanisms:

  1. It has a very low calorie content.
  2. It takes up space in the stomach and promotes a feeling of fullness (satiety), reducing food intake at a subsequent meal.

What is unique about glucomannan?

Glucomannan absorbs so much liquid that if you empty a capsule into a small glass of water, the entire thing turns into a gel. Because of this, it is important to take capsules with a full glass of water to safely and naturally assist weight loss. 

In addition to being sold as a dietary supplement, it is used as a food additive, specifically as an emulsifier and thickener denoted as E425. It is a common ingredient in foods such as pasta, noodles and tofu.

Premium grade glucomannan

Our supplement is made using 95% glucomannan extract - many competitors don't even declare their content and can use different fillers instead.

Feedback Response: Hi, I'm sorry to hear you are not satisfied with this supplement.
However, it is not supposed to work as an appetite suppressant, rather it can contribute to weight loss in the context of an energy-restricted diet.
Perhaps you may notice the benefits later.
Kind regards,
