Phosphatidylserine is a type of fatty substance called a phospholipid. Your body uses phosphatidylcholine to form the membranes that surround your brain cells. Phosphatidylserine plays an important role in keeping your brain cells healthy and allows your brain cells to communicate with each other. Your body makes phosphatidylserine from other chemicals in your body, including another phospholipid called phosphatidylcholine. When you take phosphatidylserine by mouth, it can increase the levels of phosphatidylserine in your brain. Your body seems to make less phosphatidylserine as you age. Some people may also have lower levels of this substance, including people with attention deficit hyperactivity disorder (ADHD), Parkinson’s disease, dementia, and other neurological conditions. This has led to interest in taking phosphatidylserine to improve symptoms of these conditions. But its benefits for any use are not well defined. Some studies show that it may help improve certain types of memory or recall, but these benefits were not seen in all studies or in all people. More research is needed to understand who may benefit from taking phosphatidylserine for brain health. Some people have proposed that phosphatidylserine can help reduce swelling (inflammation) in muscles, which could help reduce muscle soreness after extreme exercise. But it is unclear if phosphatidylserine can actually reduce muscle swelling or soreness.

There are no known interactions between phosphatidylserine and foods or drinks. It is unknown if drinking alcohol will affect phosphatidylserine.

Phosphatidylserine is a dietary supplement. It cannot be marketed to treat or cure a disease. Read and follow the directions on the specific product you are taking, or take it as recommended by your health care provider. Keep phosphatidylserine out of the reach of children.

These other ingredients may have different effects and side effects in the body. Read the product label closely to understand which ingredients it contains. Many years ago, phosphatidylserine supplements were made from cows. However, there were concerns that these products might be able to spread infections. Now, most phosphatidylserine products are made from soy. It is not clear if the phosphatidylserine that comes from cows is the same as the phosphatidylserine that comes from soy. These substances may have slightly different effects in the brain and body. The FDA has not tested phosphatidylserine products to confirm that they contain the ingredients stated on their labels. Some dietary supplements have been tested by third-party organizations to confirm that they contain the ingredients listed on their labels and do not contain any harmful chemicals.
