Our hybrid antioxidant and digestive-enzyme formula scavenges free radicals and reduces oxidative stress which can damage cell walls. Its proteolytic enzymes enhance Quercetin properties and contribute to good health. A great choice for a comprehensive bioflavonoid formula with additional digestive support. Quercetin Bioflavonoid Complex contains naturally sourced citrus bioflavonoids, quercetin-, and rutin-based flavonoids, along with the potent proteolytic enzyme bromelain. Flavonoids are robust compounds that lend bright colours critical for attracting pollinating insects, perform many metabolic roles, and help protect plants from disease. Widely distributed within the plant kingdom, common sources of flavonoids include apples, onions, dark-skinned berries, and the medicinal botanicals Ginkgo biloba and St. John’s wort. They contribute to the therapeutic activity many plants have displayed in experimental studies which contribute to their beneficial effects on the body. All flavonoids have the same basic chemical structure: A three-ringed molecule with hydroxyl (OH) groups attached. Flavonoids, as a rule, are antioxidants, and several of quercetin’s effects appear to be due to its antioxidant activity. Bromelain, sourced primarily from pineapple stems, is a group of proteolytic enzymes that are essential for digesting protein. Although most enzymes are considered to be poorly absorbed, the body can absorb significant amounts of bromelain. People who suffer from malabsorption can employ proteolytic type enzymes to help with their condition. Rutin has strong antioxidant properties; it can also chelate iron, thereby reducing the production of damaging oxygen radicals (Fenton reaction). Rutin also seems to stabilize vitamin C. If rutin is taken together with vitamin C, the antioxidant activity of ascorbic acid will be intensified. Quercetin Bioflavonoids Complex is an excellent supplement to help keep your health in good standing.
