Only small amounts of Phosphatidylserine can be found in dairy products or in vegetables.

Phosphatidyl Serine (PS) has proven to be a safe and effective therapeutic agent in treating memory deficit disorders and for improving other higher brain functions. Here is the information you need to see how this plant-derived substance can improve the quality of your life. Phosphatidylserine enables your brain cells to metabolize glucose and to release and bind with neurotransmitters, all of which is important to learning, memory and other cognitive functions. Phosphatidylserine increases communication between cells in your brain by increasing the number of membrane receptor sites for receiving messages. Phosphatidylserine modulates the fluidity of cell membranes essential to your brain cells' ability to send and receive chemical communication.

Scientific studies demonstrate that phosphatidylserine restores the brain's supply and output of acetylcholine, the neurotransmitter so important to memory, and so may turn back the clock in an aging brain. Phosphatidylserine can increase the availability of endogenous, that which is created within your cells, choline for de novo synthesis and release, while similar treatments with phosphatidylcholine had no effect. Phosphatidylserine also stimulates your brain to produce dopamine and this is likely why patients diagnosed with clinical depression have shown marked improvement in their symptoms as a result of taking phosphatidylserine daily. Reduced dopamine levels are also thought to contribute to attention deficit disorder and this natural substance has proven to be an effective therapeutic agent for ADD and ADHD.

Phosphatidylserine is a member of a class of chemical compounds known as phospholipids. PS is an essential component in all our cells; specifically, it is a major component of the cell membrane. The cell membrane is a kind of "skin" that surrounds living cells. Besides keeping cells intact, this membrane performs vital functions such as moving nutrients into cells and pumping waste products out of them. PS plays an important role in many of these functions. Good evidence suggests that PS can help declining mental function and depression in the elderly, and it is widely used for this purpose in Italy, Scandinavia, and other parts of Europe. PS has also been marketed as a "brain booster" for people of all ages, said to sharpen memory and increase thinking ability. However, the evidence to support this use is incomplete and inconsistent.
