Phosphatidylserine is an important phospholipid in the brain and key building block of nerve cell membranes. Research suggests phosphatidylserine may support mental focus and help support a healthy endocrine response to acute mental stress.*
Phosphatidylserine is found in high concentrations in the brain and nervous tissues, primarily found in cell membranes of neurons.¹ The body can make PS, but this important phospholipid is also found naturally in many foods (including meat, fish, and white beans).

Studies suggest levels of PS decline as we age. PS has been shown to support memory function, cognitive function and learning. It may also help support a healthy endocrine response to acute mental stress. As PS is easily absorbed through the blood-brain barrier; taking a PS supplement supports nerve cell health. When taken consistently, a PS supplement may help support cognitive, brain, and overall nerve health.

• Cognitive function

Phosphatidylserine may enhance our ability to store and retrieve memories, learn and recall information, concentrate and communicate, and solve problems. Similarly, a product with a combination of PS and the fatty acid DHA may prevent memory loss in older women.

• Locomotor function

Phosphatidylserine has been shown in studies to promote faster reaction times and reflexes.

• Exercise-induced stress and soreness

Athletes who take a PS supplement during intense periods of training may feel better emotionally after exercising. In addition, athletes who take phosphatidylserine may experience less muscle soreness.

Results of a study suggests this dietary nutrient also has a positive effect on our stress response. In one double-blind study, participants were given a PS supplement over 30 days before completing tests meant to gauge their acute mental stress. Those deemed most susceptible to stress before the study felt more relaxed after taking a PS supplement.
