Phosphatidylserine (PS) is a phospholipid that is naturally found in our cell membranes, particularly in the brain. It is crucial for maintaining the structural integrity and function of the cell membrane, as well as for facilitating intercellular communication. While our bodies can synthesize PS, we can also obtain it through our diet, specifically from animal-based foods such as fish, beef, and dairy.
Phosphatidylserine has been the subject of numerous studies and research that have shown potential benefits in enhancing cognitive function, reducing stress, and improving athletic performance. In fact, the US Food and Drug Administration (FDA) has approved the use of PS as a dietary supplement to support cognitive health.
One of the primary benefits of taking PS supplements is its ability to improve cognitive function, specifically in the areas of memory, attention, and concentration. Several studies have shown that taking PS supplements can enhance cognitive performance in individuals of all ages, but especially in older adults with age-related cognitive decline. A 2010 study published in the journal Clinical Interventions in Aging found that PS supplementation improved cognitive performance and mood in elderly participants with memory complaints.
PS supplements have also been found to reduce stress and improve mood. A 2015 study published in the Journal of Clinical Biochemistry and Nutrition found that PS supplementation reduced the levels of cortisol, a hormone associated with stress, and improved mood in healthy adults. Another study published in the journal Nutritional Neuroscience found that PS supplementation improved subjective feelings of stress in a group of young adults.
Furthermore, PS supplements have been found to improve athletic performance, specifically in reducing muscle damage and accelerating recovery time. A 2017 study published in the Journal of the International Society of Sports Nutrition found that PS supplementation improved muscle recovery in endurance athletes.
In conclusion, phosphatidylserine is a natural compound that is crucial for maintaining the structural integrity and function of cell membranes. Supplementation with PS has been found to improve cognitive function, reduce stress, and enhance athletic performance. While PS can be obtained from our diet, taking supplements may provide additional benefits, especially for those who are experiencing cognitive decline, stress, or engaging in intense physical activity.
