Phosphatidylserine (PS) is a phospholipid that is a structural component of cell membranes throughout the body, but is most concentrated in the brain and cerebral cortex. Research has demonstrated that supplemental PS possesses the ability to enhance cognitive function, specifically improving learning and concentration. Clinical trials have also shown PS to be effective in other forms of cognitive dysfunction such as age-associated memory impairment, and to improve mental stamina in high-end athletes.
Additionally, there is evidence that phosphatidylserine can significantly reduce levels of the hormone cortisol, which is released by the body in response to stress. Research has focused on the connection between lower cortisol levels and elevated mood.
Middle-aged and elderly people, and those with cognitive impairments, may benefit from phosphatidylserine’s memory-enhancing and brain-protecting powers. It can also support athletes and those under stress by reducing cortisol levels. Memory, learning, concentration and overall cognitive stamina can be improved by its use.
