Quercetin, a flavonoid found abundantly in certain fruits, is praised for its antioxidant, anti-inflammatory, and immune-modulating properties. Increasing intake through whole fruits offers a natural, nutrient-rich strategy to support health.
Apples, particularly red varieties like Red Delicious or Fuji, contain around 5 mg of quercetin per 100 g—primarily concentrated in the skin. Eating unpeeled, organically grown apples ensures higher flavonoid intake without pesticide concerns.
Berries are among the most potent sources. Cranberries top the list, offering up to 22 mg per 100 g. Blueberries range between 7–14 mg, while blackberries and elderberries provide additional, though less quantified, amounts. These fruits also contain anthocyanins, which may work synergistically with quercetin to combat oxidative stress.
Cherries, especially tart or Montmorency varieties, supply quercetin along with melatonin and anthocyanins, contributing to improved sleep, muscle recovery, and cardiovascular support.
Red grapes, another notable source, store quercetin in their skins. This contributes to the antioxidant capacity of red wine, although fresh grapes or natural juices are healthier options for daily intake.
Citrus fruits like oranges, grapefruits, and lemons offer moderate quercetin levels. Their natural vitamin C enhances quercetin’s absorption, making them a valuable addition to a bioavailable quercetin-rich diet.
Lingonberries and bilberries, less common outside Nordic regions, are quercetin powerhouses often used in traditional Scandinavian diets and supplements. These berries are rich in polyphenols and may offer protection against inflammation and metabolic disorders.
Bonus Tip: To enhance quercetin bioavailability, combine these fruits with green tea, onions, or vitamin C-rich foods. Quercetin supplements may offer higher doses but lack the synergistic compounds present in whole fruits. Regularly incorporating a variety of these fruits supports long-term health and antioxidant defense.
