How are we different?

We are the world's first provider worldwide to offer caffeine products from 100% natural, plant-based sources, with competitors typically using synthetically produced caffeine. Our natural caffeine is obtained as a highly pure water extract (50:1) from the unroasted green coffee beans (Coffea arabica) and contains a full 90% of caffeine, as well as many other valuable plant substances.

Our L-theanine is naturally derived from the green tea plant and not from generic synthetic sources. As a natural extract, this product not only has a high L-theanine content, but also includes other valuable substances from the plant including catechins and flavonoids.

Our green tea extract with hight L-theanine content comes from specialised production. We ensure not only that our green tea plants are sourced from pesticide-free cultivation, but also that the machines used for extraction are fully cleansed after every batch so that there is no possibility of extraction residues from previous batches contaminating our product.We prevent contact with any pesticides and pollutants through a special cleaning process after each individual extraction. 

For the capsule shells we use custom-made HPMC capsules that, unlike most other HPMC and pullulan capsules on the market, are 100% free from controversial additives such as carrageenans and PEG. We then package this product in environmentally friendly amber glass.

Effects

Caffeine is an alkaloid from the xanthine group. It can be found in over 60 plants, including the coffee plant, the tea bush, guarana, mate, and cola nut. Thanks to its stimulating effect on the brain and its ability to enhance motivation and concentration, caffeine is the most popular stimulant in the world. L-theanine is an amino acid similar to glutamine that occurs naturally almost exclusively in the green tea plant (Camellia sinensis). L-theanine has antioxidative properties and can protect healthy cells against oxidative stress. L-theanine can also help to regulate various neurotransmitter systems and can have a relaxing effect. Combining caffeine with L-theanine can enhance caffeine's concentration-boosting and stimulating effects, while minimising negative side effects such as uneasiness and nervousness.

Caffeine is a xanthine alkaloid found in high amounts in the seeds of the coffee bush (coffee beans). It also occurs naturally in over 60 other plants, such as the tea plant, guaraná, the mate bush and the kola nut. The discoverer of caffeine is Friedlieb Runge, who first succeeded in isolating the pure compound from coffee beans in 1819. Caffeine is also frequently added to energy drinks.

L-Theanine

L-theanine is an amino acid similar to glutamine. In nature, L-theanine occurs almost exclusively in the green tea plant (Camellia sinensis). This special compound is partly responsible for the flavour of tea, reducing the bitterness and ensuring a full flavour. It cannot be produced endogenously (by the body) and is not converted into proteins.
