Quercetin, a cousin of Rutin, is a unique bioflavonoid that has been extensively studied by researchers around the world. Bioflavonoids are found as the pigments in leaves, barks, rinds, seeds, and flowers, usually in close association with Vitamin C. Together the two compounds seem to provide antioxidant protection to plants, helping them withstand exposure to climatic variations in wind, rainfall, temperature and sunlight. Bioflavonoids are also important for human health, but unfortunately cannot be manufactured by the body and must be supplied either from supplements or foods.
Bioflavonoids were first discovered by Nobel Prize Laureate Albert Szent-Gyorgy in the 1930’s. Bioflavonoids act to protect and preserve the structure of capillary blood vessels, promote circulation, stimulate bile production and lower cholesterol levels.
Since his groundbreaking work researchers have been able to isolate Quercetin from blue-green algae. Quercetin has been the subject of dozens of scientific reports over the past 30 years. Quercetin has a unique synergistic relationship with Vitamin C, and taken together both improve the efficacy of the other.
