Quercetin is a plant flavonoid that provides immunity support, helps with anti-inflammatory functions, and promotes cardiovascular health.1

    Quercetin as oxidative stress-buster
    Quercetin exerts a protective shield against deleterious effects of free radicals and oxidative stress. As evidenced in published research, quercetin reduces oxidative stress in the upper respiratory tract,2 and effectively prevents replication of harmful microbes in our body.3, 4, 5

    Quercetin supports vessels health
    Several published studies have suggested that quercetin supplementation provides unique protection to endothelial health.6 It helps to maintain healthy blood pressure,7,8 total cholesterol, LDL-cholesterol, and blood homocysteine concentration.9

    Inhibits inflammatory factors
    In clinical trials, quercetin supplementation boosted anti-inflammatory responses in women with joints discomfort,10, 11 and inhibited expression of pro-inflammatory factors.12 In another clinical study, quercetin exhibited protection against unhealthy progression of cells in different organs.13, 14

    Quercetin helps to maintain healthy blood sugar levels
    Quercetin is quite an active agent to maintain healthy blood sugar. In a clinical trial, quercetin supplementation improved fasting blood glucose level, hormonal resistance and hormonal profile of women.15 Another study showed similar results in overweight women.16

    Quercetin boosts brain health
    Quercetin’s unique antioxidant properties are gaining attention in maintaining brain health and in getting better cognitive output. It protects neuronal cells from oxidative stress and toxicity in the brain induced by mitochondrial dysfunction.17, 18
