    What is Phosphatidylserine?

    Phosphatidylserine (abbreviated Ptd-L-Ser or PS) is a phospholipid and is a component of the cell membrane. It plays a key role in cell cycle signaling, specifically in relationship to apoptosis.

    Phosphatidylserine is a chemical that is present in the human body. The body can make phosphatidylserine, but most of what it needs comes from foods. Phosphatidylserine can also be taken as a supplement. These supplements were once made from cow brains.Now they are commonly made from cabbage or soy.

    Phosphatidylserine is used for Alzheimer disease, dementia, decline in memory and thinking skills that occurs normally with age,athletic performance, and many other conditions, but there is no good scientific evidence to support most of these uses.

     

    Function of Phosphatidylserine

    1. Decline in memory and thinking skills that occurs normally with age. Phosphatidylserine seems to improve attention, language skills, and memory in aging people with declining thinking skills. Most research has used phosphatidylserine from cow brains.But most phosphatidylserine supplements are now made from soy or cabbage. There is limited research showing that plant-derived phosphatidylserine also improves memory in people with age-related memory loss. Taking phosphatidylserine might also reduce person's risk for a decline in memory and thinking skills with age. But research is limited and unclear.

     

    2. Alzheimer disease. Taking phosphatidylserine can improve some of the symptoms of Alzheimer disease after 6-12 weeks of treatment. It seems to work best in people with less severe symptoms. But phosphatidylserine might become less effective over time. After 16 weeks of treatment, progression of Alzheimer disease seems to overcome any benefit provided by phosphatidylserine.Most research has used phosphatidylserine from cow brains. But most phosphatidylserine supplements are now made from soy or cabbage. Researchers do not yet know how phosphatidylserine made from these plant sources compares with phosphatidylserine made from cow brains in terms of effectiveness for Alzheimer disease.
