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.
The quercetin is derived from a 100% natural, purely plant-based extract from the flowers 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, 400m 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, which is the most expensive 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; further, 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.
