Product Description

Finest Sophora Japonica Extract | Quercetin | Natural Antioxidant ingredient | Direct Supply
Sophora Japonica Extract Quercetin is a natural flavonoid compound extracted from dried Sophora japonica flower buds. Quercetin’s unique properties allow it to interact synergistically with other bioflavonoids, and it may improve the absorption of other supplements as well.

Quercetin is an effective antioxidant, and it scavenges free radicals. Free radicals can damage cells and cause oxidative stress. Antioxidants prevent free radicals from accumulating and causing health problems. Quercetin also has anti-inflammatory properties and helps support the immune system.
