"The primary cause of altitude sickness is lack of oxygen. Ginkgo can help protect against altitude sickness through its ability to improve blood flow, and thus oxygen delivery to the brain."
— Dr. Edward Rosick, Physician, Pennsylvania State University
Ginkgo biloba has a remarkable ability to increase blood flow, enabling it to cope better with decreased atmospheric oxygen levels. Antioxidant properties in the leaf extract increase vasodilation and peripheral blood flow in capillary vessels. Better blood flow at altitude delivers more oxygen to your brain — eliminating — and to your muscles, allowing you to bike, run or ski all day without feeling weak.*
