Guarana Seed Extract

Guarana seed extract has ten times more antioxidant catechins than green tea. The U.K. study found that guarana has positive effects on oxidative stress, plasma catechins, and erythrocyte enzyme activity in red blood cells. Guarana extract reduced DNA cell damage and oxidative cell damage in the lymphatic system. The study further showed that guarana provides a long-term antioxidant effect. Researchers concluded that guarana catechins: enhance plasma antioxidant activity minimize plasma lipid oxidation protect erythrocyte DNA increase antioxidant enzyme activity Guarana consumption also had a long-term antioxidizing effect, even after the plasma catechins left the blood. url:http://www.hosunbio.com
