Description

Quercetin Powder is extracted from the Sophora flavescens Ait. Quercetin is a potent antioxidant and has anti-inflammatory activity, protecting cellular structures and blood vessels from the damaging effects of free radicals. It improves blood vessel strength.

Quercetin not only participates in the oxidation in vitro, can inhibit DNA oxidative damage, but also can protect tissues from oxidative damage by reducing the concentration of peroxide in tissues in vivo.As an antioxidant, it reduces LDL cholesterol and offers protection from heart disease. Quercetin blocks an enzyme that leads to accumulation of sorbitol, which has been linked to nerve, eye, and kidney damage in diabetics.
