Quercetin: Sources

Quercetin occurs naturally in many foods from nature. Apples are a major source of Quercetin due to their wide consumption. Other fruits containing Quercetin include cherries, raspberries, blueberries, blackberries, red grapes and citrus fruits. Tomatoes, onion, kale, leek and broccoli are other sources. Beverages such as red wine and green or black tea also contain Quercetin. Other sources include the edible garnish parsley, capers and leafy green vegetables. Although the Quercetin content, as shown below, is relatively small, it is the critical flavonoid found in these foods, making them “superfoods”.

Quercegen’s science team is continually striving to improve its proprietary extraction and purification process so that Quercetin can be readily available to add to foods, replacing the idea of eating 50 apples a day to ingest 500 mg of Quercetin, which can be obtained by eating only 2 Q-Force chews.
