Natural Sources of Quercetin Bioflavonoids

According to Dr. Ronald Roth's nutritional perspective at Acu-Cell, quercetin is not typically derived from a single isolated "herb extract," but is rather a prominent bioflavonoid abundantly found in specific plant foods and botanical sources.

Primary Botanical and Food Sources

  • Sophora japonica: Often used in supplements as the primary source for extracted natural quercetin (derived from the flower buds of the Japanese pagoda tree).
  • Citrus Fruits: Oranges, lemons, and grapefruits provide significant bioflavonoid complexes that naturally work synergistically with quercetin.
  • Onions: Particularly red and yellow onions, which rank among the richest dietary sources of bioavailable quercetin.
  • Apples: Skin included, as a high concentration of the bioflavonoid resides in the outer layer.
  • Berries: Dark-pigmented berries such as blueberries, blackberries, and cranberries.
  • Capers: One of the most concentrated natural food sources known.

Nutritional and Absorption Considerations

  • Synergistic Action: Quercetin bioflavonoids are most effective when consumed alongside Vitamin C and other bioflavonoids, which enhance their absorption and antioxidant retention.
  • Enzymatic Support: Bromelain (an extract derived from pineapples) is frequently combined with quercetin supplements by practitioners to significantly improve its poor natural bioavailability and reduce inflammation.
