FAQ

We have the answers

The product contains quercetin powder with a specification of at least 95% quercetin as its only functional ingredient, without added fillers, colourings or preservatives.

The quercetin is obtained from an extract of the flowers of the Japanese pagoda tree (Sophora japonica), a natural source with a high content of quercetin and the related flavonoid rutin.

Each daily serving of 1 level measuring scoop provides 500 mg of quercetin powder.

No nutrient reference value (NRV) is currently established for Quercetin under the EU Food Information Regulation.

The powder contains only quercetin extract, with no added carrier substances such as starch, gluten or lactose.

Each batch of raw materials is independently tested for heavy metals and contaminants; only raw materials that remain well below the specified limits are used.

The current certificate of analysis, including detailed laboratory results, is available under the “Laboratory Analysis” tab.

As quercetin extracts are generally plant-derived, for example from the Japanese pagoda tree (Sophora japonica), and no animal-derived ingredients are added, the powder is considered suitable for vegetarians and vegans.

One 30 g pouch of quercetin powder provides approximately 60 days' supply at a daily intake of 1 level measuring scoop (500 mg). Three pouches containing a total of 90 g provide approximately 180 days' supply at the same dosage.

One level measuring scoop contains 500 mg of quercetin powder. The recommended number of scoops provides the daily intake stated on the product label.

We recommend mixing 1 level measuring scoop of quercetin powder (500 mg) into a sufficient amount of liquid each day and taking it with a meal, preferably at lunchtime. The appropriate amount of liquid may vary from person to person; we recommend one glass of water (approximately 250 ml).

Food supplements should not be used as a substitute for a varied and balanced diet and a healthy lifestyle. Do not exceed the stated recommended daily amount.

Taking the product with a meal is generally better tolerated. Sensitive individuals may be more likely to experience gastrointestinal discomfort when taking it on an empty stomach.

The powder can be stirred into drinks that are not too hot, such as water, juice or smoothies, or mixed into yogurt and similar foods. Very hot liquids should be avoided so that the substance’s stability is not unnecessarily affected.

If a serving is missed, it can be taken later the same day as long as the recommended total daily amount is not exceeded. Do not take a double dose at once to compensate.

When using the product for the first time, it may be helpful to start with a smaller daily amount and gradually increase to the full recommended daily serving while monitoring individual tolerance.

This can be assessed through individual guidance from medical or nutritional professionals, pharmacies or qualified nutritionists. Your supplement routine, medical history, medication and laboratory values are reviewed together to coordinate suitable doses and combinations.

The best-before date is printed on the back of the pouch. When stored as directed, the product will retain its stated quality until this date.

For larger orders, please contact our customer service team to confirm the best-before date of the current batch.

Store the product in a cool, dry place, tightly closed and protected from light and direct sunlight. Keep out of reach of children.

Refrigeration is generally not required as long as the powder is stored dry and protected from heat. At very high ambient temperatures, slightly cooler storage may help maintain product quality for longer.

Yes. Keep the product tightly closed, dry and protected from excessive heat and direct sunlight while traveling.

Each batch is tested for identity, active-ingredient content, microbiological parameters such as total microbial count, yeasts and molds, and other quality-relevant indicators. The specific parameters are listed in the certificate of analysis.

The analyses for the quercetin powder are performed by Limbach Analytics GmbH, Arotop Laboratories Mainz, an independent German testing laboratory accredited according to DIN EN ISO/IEC 17025:2018 and specializing in food, fat and oil analysis. The laboratory uses standardized, validated methods and has extensive experience analyzing food supplements.

In clinical practice, laboratory parameters used to assess general metabolic status and cardiovascular risk are usually the main focus, for example blood pressure, blood lipids, inflammatory markers or blood glucose. Specific routine tests solely for quercetin are not generally performed. Which examinations are useful in an individual case should always be decided together with qualified medical professionals, particularly in the presence of existing medical conditions, planned long-term use of higher amounts of quercetin or simultaneous use of other food supplements and medicines.
