Quercetin is powerful antioxidant

The most important ingredient is Quercetin, a powerful antioxidant found in the skins of grapes, apples and vegetables that has known anti-inflammatory effects. Experts believe Quercetin helps extend your natural energy by inhibiting an enzyme called COMT. Additionally, FRS's patented formula of Quercetin and green tea extracts promote thermogenesis, which increases the metabolic rate and helps the body burn excess carbohydrates and fat.
