Phosphatidylserine is one of the five phospholipids which are needed for the structure and good functioning of all of the cells of the body and has some some unique functions.
It regulates the state of key proteins in cell membranes, facilitates membrane-to-membrane fusion and activates the receptors on cell surfaces which help the cell to respond to chemical messengers.
A number of trials have successfully used Phosphatidylserine to treat age -related reductions in memory, learning and concentration.
In May, 2003 the Food and Drug Administration gave “qualified health claim” status thus allowing labels to state “consumption of Phosphatidylserine may reduce the risk of dementia and cognitive dysfunction in the elderly” along with the disclaimer.
In athletes, Phosphatidylserine has been shown to improve performance, endocrine response to exercise stress, and decrease muscle damage in athletes involved in cycling, weight training, golf and endurance running.
It has also been reported to be an effective supplement for combating exercise-induced stress by reducing the exercise-induced increase in cortisol levels in a dose dependent manner.
