How are we different?

We source our organic konjac root powder from a certified organic producer in China. The company prioritises close cooperation with local farmers and supports them in the implementation of pesticide-free, organic cultivation. It has many years of experience in the production of certified organic food and animal feed.

Our organic konjac glucomannan is a pure, natural product, which is obtained exclusively from the root tubers of konjac. The freshly harvested konjac roots are gently cleaned, freed from the buds, then cut into slices. These slices are then dried at temperatures of up to 190°C. After drying, the konjac slices are passed through a 2-step grinding process. After the first and second grinding stages, coarser pieces of root are sieved out to produce a fine, beige-brown powder. This is dried again under heat.

Our organic konjac root powder has a glucomannan content of at least 95%.

For the capsule shells we use custom-made HPMC capsules that, unlike most other HPMC capsules that can be found on the market, are 100% free from controversial additives such as carrageenans and PEG. We use environmentally friendly amber glass jars for the packaging of this product.

Konjac (Amorphophallus konjac), also called devil's tongue, is a plant of the Amorphophallus genus from the Araceae family. The perennial herbaceous plant is native mainly to the Asian region and is fairly low maintenance. In spring, the konjac tubers (also called konjac roots) sprout a single leaf. The inflorescences and fruit clusters are similar to those of arum, a plant which is native to Germany and belongs to the same family.

In Asia, the root tubers of konjac are traditionally cultivated and consumed in a way similar to the root tubers of Jerusalem artichokes, potatoes and sweet potatoes.

From a nutritional perspective, glucomannan, like other dietary fibers, is an important dietary fibre that can be used as a natural food source by microorganisms such as bifido-bacteria and lacto-bacteria.

Health Claims (as per EFSA):

  • Glucomannan contributes to weight loss in the context of a low-calorie diet
