Product Introduction

Phosphatidylserine(abbreviated Ptd-L-Ser or PS) is a phospholipid and is a component of the cell membrane.. The body can make phosphatidylserine, but gets most of what it needs from foods.plays a key role in cell cycle signaling, specifically in relationship to apoptosis. Phosphatidylserine supplements were once made from cow brains, but now are commonly manufactured from cabbage or soy to avoid infections such as mad cow disease.

Uses/Benefits/Effects

Phosphatidylserine is used for Alzheimer's disease, age-related decline in mental function, improving thinking skills in young people, attention deficit-hyperactivity disorder (ADHD), depression, preventing exercise-induced stress, and improving athletic performance.

In May, 2003 the FDA has gave "qualified health claim" status to phosphatidylserine thus allowing labels to state "consumption of phosphatidylserine may reduce the risk of dementia and cognitive dysfunction in the elderly"

Studies also shows that Phosphatidylserine can improve attention, language skills, and memory in aging people with declining thinking skills.

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. PS has been reported to be an effective supplement for combating exercise-induced stress by blunting the exercise-induced increase in cortisol levels in a dose dependent manner. PS supplementation promotes a desirable hormonal balance for athletes and might attenuate the physiological deterioration that accompanies overtraining and/or overstretching.In recent studies, PS has been shown to enhance mood in a cohort of young people during mental stress and to improve accuracy during tee-off by increasing the stress resistance of golfers.

Dosage and Safety

Soy-derived PS is designated Generally Recognized As Safe by the FDA.A 2002 safety report determined supplementation in elder people at a dosage of 200 mg three times daily to be safe.
