Phosphatidylserine: Natural Support for Memory and Learning*

Phosphatidylserine (PS) is a nutritional supplement that has been shown to help maintain healthy cognitive brain function in adults. Chemically, PS is a naturally occurring phospholipid, or “good fat”, that is found in cell membranes and is essential to the functioning of all cells in the body. It is, however, particularly abundant in brain cells where it functions as a brain cell regulator with regard to neurotransmission and synaptic communication.*

Both neurotransmission and synaptic communication are key elements in maintaining memory, supporting the ability to learn, and promoting sustained concentration. As the brain ages, people naturally experience a noticeable decline in the ability to recall facts and events, learn new things, and concentrate for extended periods. Preliminary research has shown that PS supplementation, when combined with a healthy diet and lifestyle, can help maintain healthy memory and mental clarity.(1) An individual’s quality of life can be substantially improved by supporting memory, learning, and concentration.*

Existing clinical data suggest that PS is most effective at an initial dosage of 300 to 500 mg of phosphatidylserine per day for the first month, taken at one time or evenly split into two or three dosages taken throughout the day. It takes approximately 30 days to notice positive effects. After 30 days, supplementation may be reduced to a maintenance level of 100 to 200 mg per day.
