Phosphatidyl Serine

Phosphatidylserine is an amino acid derivative and is found in high amounts in the brain. It helps cells keep intact and is proven to improve mental focus, memory, mood, and bone health.

Supporting research & information


Phosphatidylserine (PS) is a phospholipid and is a component of the cell membrane.

1) Phosphatidylserine Improves Memory

Phosphatidylserine supplementation increased the speed of calculations done in short-term memory by 20% in a group of healthy adult volunteers[R].

Children with ADHD also saw in improvement in short-term memory after supplementing phosphatidylserine [R].

Senior citizens who supplemented phosphatidylserine had a lower incidence of short-term memory complaints following supplementation [R, R].

2) Phosphatidylserine Improves Stress Response

Supplementing phosphatidylserine lowered the release of cortisol, the hormone which is associated with many of the negative effects of stress [R].    

Studies also found that subjective responses to stress, measured in a survey known as the Trier Social Stress Test (TSST), were improved with the supplementation of phosphatidylserine [R, R].

Phosphatidylserine is a fatty substance called a phospholipid. It covers and protects the cells in your brain and carries messages between them.

Phosphatidylserine plays an important role in keeping your mind and memory sharp. Animal studies suggest that the level of this substance in the brain decreases with age.

Why do people take phosphatidylserine?

Phosphatidylserine is taken to try to prevent memory loss and mental decline that may occur as you get older.

Several studies suggest that it may boost your brain power. People who took the supplement scored higher on short-term memory, mood, and concentration tests. For example, they could better recall names and objects. Much more research is needed to confirm these results.

Scientists have used phosphatidylserine in studies to treat symptoms of Alzheimer's disease. Again, there is not enough evidence that phosphatidylserine is of any help in treating this condition.
