What Is It?
Quercetin belongs to the flavonoid class of antioxidants commonly found in citrus fruits. Its use has been widely established, particularly in Europe, for the treatment of a variety of ailments including allergy symptoms, diabetic complications and cardiovascular concerns, all thanks to its anti-inflammatory effects.
What Does It Do?
Primary Uses: Quercetin promotes cardiovascular health due to its antioxidant and anti-inflammatory effects. It reduces the oxidation of low density lipoproteins (LDL), promotes healthy blood pressure and blood clotting, enhances nitric oxide (NO) production, and reduces the risk of metabolic syndrome.
Secondary Uses: Quercetin inhibits the production of inflammatory signaling molecules by a mechanism similar to that of aspirin. Quercetin also inhibits the release of histamine from certain immune cells and is therefore widely used by those who suffer from constant allergies (such as dust) and seasonal allergies (such as hay fever).
Who Should Take It?
Quercetin can add a boost for anyone at risk or suffering from any cardiovascular condition, battling allergies or plagued with headaches.
