Main highlights

Made in Germany – our vegan Quercetin capsules high dose are carefully manufactured in Germany and thoroughly tested by a certified laboratory for harmful substances such as heavy metals, bacteria, mould and strain caused by ethylene oxide (EtO).
High dose and natural - we obtain our Quercetin high dose from the flowers of the Japanese string tree (Sophora japonica). We use a high-dose 15:1 extract – i.e. from 15 parts of the starting material, we obtain 1 part of the final product as part of the extraction process. This is standardised to at least 95% quercetin content and contains no synthetic quercetin, which has a low bioavailability.
Glass instead of plastic - Our Quercetin high dose is produced exclusively in sustainable pharmacist jars with aluminium lids or in environmentally friendly refill bags made of kraft paper. So you do not only good for your body, but also the environment.
100% True Clean Label - Our Quercetin capsules contains only what we also declare on the product label. We do not use auxiliaries, fillers or fluids. Since quercetin is a particularly difficult raw material to fill, many suppliers use fluids. We therefore fill our Quercetin very elaborately on semi-automatic machines and can therefore do without it.
*Test winner – in the test 02/2023 in the category "Quercetin" from "Test winner Online" our Quercetin capsules were rated with a high dose of 1.1. In particular, the fact that, in addition to the usual analyses for heavy metals, microbial or ethylene oxide exposure, we also have the active ingredient content, i.e. the actual proportion of quercetin per capsule, checked positively in distinction from most competitors.

Proven formula – finally available again – for almost 6 years, our team around Dr. Stockmann has been researching and developing the basic raw material quercetin from Japanese string tree. Due to our many years of experience and partnerships with local farmers/suppliers, we can always offer the best raw material quality. Quality is our top priority, not the quick sale of a cheap product. Our goal is that you buy our product again and again because it convinces you - that's why we offer you the best product at a fair purchase price.
Optimised bio-availability - Thanks to the gentle drying process, powdering and subsequent water-ethanol extraction, the bioavailability is many times higher than cheap extracts. Each of our vegan capsules contains 500 mg of pure quercetin - 12500 mg Japanese Schhnur tree were processed per capsule.
Free radical catcher - Quercetin is one of the bioflavonoids. As plant pigments, they are responsible for the colouring of the flowers and leaves and serve the plant as protection against environmental influences and unwanted bacteria. A particularly high content of quercetin is found in the shell of plants and fruits. No shell - no quercetin.
Focus on your health – At Scheunengut it is particularly important that all our products deliver noticeable added value without exposing you to risks due to unnecessary additives. Therefore, we do not use release agents, preservatives, etc. - according to the motto - no additives, only active ingredients.
Convincing 4-month treatment – with regular intake of 1 capsule per day, our Quercetin tin with 120 capsules lasts exactly 4 months. The daily price/capsule does not exceed 25 cents and thus protects your wallet with maximum effect. Permanent application is possible without any problems.
