The brain requires high amounts of oxygen and nutrients from the blood to function properly.

As we age, our gastrointestinal system is not as efficient in absorbing nutrients from our food, and the circulatory system becomes less effective in delivering oxygen to the tissues, potentially slowing brain activity. In later years the central nervous system needs help to obtain the nutrients needed for optimal functioning. Ginkgo-PS combines two powerful aids to brain function in a single supplement-ginkgo biloba, and phosphatidylserine (PS)-for benefits that include optimal mental performance, memory, and general cognitive function.

1. Combines standardized, high-potency Ginkgo biloba extract, plus phosphatidylserine for healthy mental and cognitive function
2. Acts as a vasodilator to improve blood circulation in the brain
3. Contains phosphatidylserine (PS), which is clinically proven to enhance memory
