How are we different?

Our Neurox Quercetin Complex is a unique combination of high-dose vitamin B1 and quercetin from Sophora japonica flower extract, EGCG (green tea extract), ginkgo biloba and taxifolin. This results in an extremely potent complex with a high level of synergy.

For the quercetin, we use a 100% natural, purely plant-based extract from the blossoms of the Japanese pagoda tree (Sophora Japonica). This is standardised to at least 95% quercetin content and contains no synthetic quercetin, which has low bioavailability. The pure water-ethanol extraction process eliminates the need for other extraction agents such as N-hexane or methanol.

Our ginkgo biloba extract (45:1) comes directly from its native environment in a nature reserve in southern China. After the harvest, the leaves undergo a gentle extraction process using food-grade alcohol and pure water in a ratio of 45:1. This produces a particularly concentrated extract with 26.86% flavone glycosides at reference values of 22-27% as well as 6.77% ginkgolides with a very low content of ginkolic acid.

The pesticide-free green tea leaves for our highly concentrated and decaffeinated green tea extract, which contains an outstanding 96% EGCG (epigallocatechin gallate), come from the Chinese province of Zhejiang, 400 metres above sea level. The tea grows there in remote regions in optimal climatic conditions. The tea leaves are only harvested for consumption once a year, when the chatechin content, especially EGCG, is particularly high.

Our green tea extract is made from 100% green tea leaves (Camellia sinensis var. sinensis) and is produced exclusively by pure water extraction. Water extraction is the most expensive extraction process for obtaining green tea extracts. No chemical solvents such as N-hexane or acetone are used in this process, so our pesticide-free green tea extract is completely free of residues. The water used for extraction is not re-used for further extractions. This results in an especially pure extract with a total polyphenol content of over 99% and an EGCG content of 96%. Decaffeination takes place during the extraction process, which means that the caffeine content in the extract can be reduced to less than 0.1%.

Our vitamin B1 is present as thiamine hydrochloride, a stable and very effective form of vitamin B1. Since the immediately active form of vitamin B1 is not approved as a food supplement in all countries, we have chosen a particularly high-quality, plant-based premium raw material of the highest possible bioavailability and purity.

The natural taxifolin (dihydroquercetin) is obtained from larch trees (Larix gmelinii) via a highly purified water-ethanol extraction process. The use of carriers such as maltodextrin or silicon dioxide and the use of genetic engineering is deliberately avoided in the production process.

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.

Quercetin complex Neurox

Quercetin

Bioflavonoids, a class of plant compounds which includes quercetin, are the most abundant polyphenols (aromatic compounds) in the plant kingdom. As plant pigments, they are responsible for both the colouring of flowers and leaves as well as for protecting the plants against environmental damage.

Quercetin is particularly concentrated in the outer layers of plants and fruits in order to protect them. Foods rich in quercetin include grapes, apples and onions. Removing the skins or shells of such fruits and vegetables, however, effectively strips these foods of their quercetin. The name of this potent flavonoid is derived from the Latin "quercus" (oak) due to the high concentrations of the potent flavonoid discovered in the tree's bark. However, it is not only oak trees that are rich in quercetin; the bark and outer layers of other trees also contain large quantities of this antioxidative compound.

The Japanese pagoda tree (Sophora japonica), from whose flowers we extract our 100% natural and bioavailable quercetin, contains exceptionally high amounts.

Ginkgo biloba

The Chinese ginkgo biloba tree is considered a sacred tree in its native East Asia and, like the olive tree, is one of the oldest and most resilient trees on earth. The oldest specimens are typically found in Japan and China in temples and pilgrimage sites, where they are revered as a symbol of longevity, love, fertility and hope, reaching a considerable growth height of up to 40m. Ginkgo leaves have also traditionally been used in China to protect books from pests, while the nuts have been used in Chinese traditional medicine. The leaves of the Ginkgo Biloba tree contain valuable terpenes such as ginkgolides and bilobalide as well as flavone glycosides.

Green Tea Extract – EGCG

EGCG (epigallocatechin gallate) is a secondary plant substance that is particularly abundant in the leaves of the plant. Plants produce more of these secondary plant substances to protect themselves from strong sunlight. Due to the concentrated polyphenols, our extract does not contain the amino acids usually found in green tea, making the caffeine more tolerable. Our green tea extract is therefore designed to be caffeine-free and contains less than 0.1% caffeine. This makes it suitable for caffeine-sensitive people and can also be consumed in the evening.

Taxifolin

Taxifolin (dihydroquercetin) is a flavonoid, which occurs naturally in onions, apple peels, citrus fruits and in the wood of various conifers, including the bark of larch trees (Larix gmelinii). Larch is very popular in the timber industry because of its durability and resistance. A number of plant constituents are responsible for these positive properties, including taxifolin, which is present in high quantities.

Vitamin B1 (Thiamine)

Vitamin B1 (thiamine) is the precursor of the coenzyme thiamine pyrophosphate (TPP, also thiamine diphosphate, TDP), which performs many important tasks in the body. Vitamin B1 is found in almost all organs and tissues of the body and has a significant influence on the central and peripheral nervous system. Here it is particularly important for the transmission of signals between the nerves and muscles, thus playing a key role in the function of the nervous system. Vitamin B1 is also an important vitamin for the regeneration of the nervous system.

Vitamin B1 is also involved in the metabolism of some neurotransmitters such as acetylcholine and thus contributes to the maintenance of normal mental function.

Another important area of action of vitamin B1 is the extraction of energy from food. The B1 coenzyme TPP plays an important role in the citrate cycle of the mitochondria. Here it has a key function in the aerobic breakdown of glucose.

Vitamin B1 (Thiamine)

According to the European Food Safety Authority (EFSA), vitamin B1 contributes to:

  • normal function of the nervous system,
  • normal energy metabolism,
  • normal mental function,
  • normal heart function.
