ENHANCED ABSORPTION: Our formula combines quercetin with vitamin C and bioflavonoids, which are often found together in nature and work in mutually enhancing ways. Vitamin C helps the absorption of quercetin and may boost its effectiveness by recycling quercetin in the body.* IMMUNE SUPPORT SYNERGY: Quercetin and vitamin C have overlapping benefits for immune support and respiratory health, and research suggests they may work better when combined.* Emerging research suggests that quercetin may also help limit respiratory allergy symptoms.* CARDIOVASCULAR SUPPORT: Quercetin and citrus bioflavonoids help support arterial health by protecting against damage from free radicals, helping blood vessels dilate for healthy circulation, and protecting against cholesterol oxidation (which can eventually harden arteries).* HEALTHY AGING: Quercetin is a potent antioxidant that can cross the blood-brain barrier and help protect against oxidative stress, a key contributor to cellular aging.* Emerging research suggests that quercetin may also help reduce cellular senescence, another aging contributor.* FROM NATURE WITH LOVE: Our plant-based formula features quercetin, a plant pigment found in elderberry and red wine grapes, along with vitamin C from acerola cherry and bioflavonoids from citrus fruits. Non-GMO and vegan with no preservatives, coloring or flavoring.
