Phosphatidylserine (abbreviated Ptd-L-Ser or PS) is a phospholipid and is a component of the cell membrane. It is derived from natural soybean.  It plays a key role in cell cycle signaling, specifically in relationship to apoptosis.
Phosphatidylserine is a fatty substance called a phospholipid. It covers and protects the cells in your brain and carries messages between them.

Phosphatidylserine plays an important role in keeping your mind and memory sharp. Animal studies suggest that the level of this substance in the brain decreases with age.

WHY DO PEOPLE TAKE PHOSPHATIDYLSERINE?

Phosphatidylserine is taken to try to prevent memory loss and mental decline that may occur as you get older.

Several studies suggest that it may boost your brain power. People who took the supplement scored higher on short-term memory, mood, and concentration tests. For example, they could better recall names and objects. Much more research is needed to confirm these results.

Phosphatidylserine has been suggested in the treatment of the following conditions, as well:

• Muscle soreness and stress in athletes who overtrain
• Multiple sclerosis

Phosphatidylserine Application & Benefits
To effectively improve the vitality of brain cells, preventing Alzheimer’s disease To stabilize mood and improve sleep To increase attention, improving the symptoms of ADHD, etc. Prevention and treatment of cardiovascular and cerebrovascular diseases To scavenge free radicals, anti-oxidation To improve immunity.

1) Phosphatidylserine Improves Memory

Phosphatidylserine supplementation increased the speed of calculations done in short-term memory by 20% in a group of healthy adult volunteers.

Children with ADHD also saw in improvement in short-term memory after supplementing phosphatidylserine.

Senior citizens who supplemented phosphatidylserine had a lower incidence of short-term memory complaints following supplementation.
2) Phosphatidylserine Improves Stress Response

Supplementing phosphatidylserine lowered the release of cortisol, the hormone which is associated with many of the negative effects of stress.

Studies also found that subjective responses to stress, measured in a survey known as the Trier Social Stress Test (TSST), were improved with the supplementation of phosphatidylserine.
3) Phosphatidylserine Aids Athletic Performance

Phosphatidylserine may also increase the time that it takes for people who are exercising to become tired.  This could help athletes gain more of the positive effects of excercising by exercising more.

While exercise brings a huge number of benefits, it can also cause a temporary increase of stress hormones.Phosphatidylserine measurably reduced the negative hormonal response to exercise in multiple studies, which could be beneficial to athletes.

One study also found a correlation with increased performance in subjective athletic ability in trained golfers following supplementation.
4) Phosphatidylserine Helps Relieve ADHD Symptoms in Children

Phosphatidylserine supplementation improved ADHD symptoms in children with ADHD. More research may be needed to see if the same efficacy is seen in adults.

A DB-RCT showed Phosphatidylserine supplementation (300mg PS-Omega3/day for 15 weeks) was safe and tolerated well.
5) Phosphatidylserine Helps Prevent and Treat Alzheimer’s Disease

The hereditary form of Alzheimer’s is associated with an accumulation of a  chemical waste substance called amyloid beta in the brain.  Studies have shown that phosphatidylserine prevents  amyloid beta from accumulating in the brain, which could help prevent or slow the progression of the disease.
6) Phosphatidylserine Aids Recovery From Injury

Due to the many roles that it plays as an integral part of cell structure, there is evidence that phosphatidylserine may aid recovery from physical injury.

Phosphatidylserine may contribute to recovery from reduced blood flow.

Due to phospatidylserine’s integral role in cell membranes, researchers have suggested that phosphatidylserine could aid in recovery after situations resulting in impaired blood flow, such as heart disease.

Phosphatidylserine also aids in the formation of bones from minerals in the body, and researchers have suggested potential applications for phosphatidylserine as a bone repairing molecule for use in recovery from surgery.
