Flavonoids in Dark Chocolate
A recent study in the journal Circulation found that flavonoids in dark chocolate improve circulation. That could be good for erection problems that are due to poor circulation. Flavonoids are naturally-occurring antioxidants that protect plants from toxins and help repair cell damage. Studies show that flavonoids and other antioxidants have similar effects on people. They may help lower blood pressure and decrease cholesterol, both of which are factors that contribute to erectile dysfunction.
