Quercetin is a plant-sourced antioxidant used in herbal medicine as a blood-vessel protectant. Ongoing research proves exciting for the current role of quercetin in global health.

Quercetin is a naturally occurring flavonoid (plant pigment) which is found in many plants including onions, apples, kale, green tea, and multiple species of berries. Its antioxidant activity makes these plants resilient and protects their cells from environmental stressors. This in turn bodes well for their antioxidant potential in supplement form.

The antioxidant action of quercetin is recognized for numerous human health benefits including use in herbal medicine as a blood-vessel protectant. Quercetin has a long history of traditional use, with current research showing promise for potential added health benefits.

Consuming quercetin-rich foods is a good start; however, quercetin in supplement form gives an exponentially greater quantity of this critical compound. It delivers an amount which more closely reflects dosage used in current therapeutic research.  

Each capsule of New Roots Herbal’s Quercetin contains 500 mg of naturally sourced, potency-validated quercetin.
