Phosphatidyl L-serine Background and Benefits

Phosphatidyl l-serine, also known as phosphatidylserine, is a chemical classified as a phospholipid. It is a primary component of cell membranes and also plays a key role in apoptosis, which is the process of programmed cell death (PCD) that occurs in many multi-celled organisms.

Some bacteria can biosynthesize phosphatidyl l-serine from the amino acid serine by activating phosphatidic acid with cytidine diphosphate-activated phosphatidic acid. Mammals can synthesize phosphatidyl l-serine from phosphatidylethanolamine and phosphatidylcholine. Conversely, the liver can also synthesize phosphatidylcholine from phosphatidyl l-serine.

Humans typically obtain most of the phosphatidyl l-serine they require from dietary sources. People in Western countries consume an average of 130 mg phosphatidyl l-serine per day, primarily from animal protein. The most abundant animal-based sources of phosphatidyl l-serine include Atlantic mackerel and Atlantic herring. 

Phosphatidyl l-serine is also available via plant sources, phosphatidylserine (from sunflower lecithin) is non-GMO and vegan. This form is used in Xtendlife products, including the Total Balance range and Think Sharp. It is a concentrated form and also contains lesser amounts of other dietary phospholipids including phosphatidylcholine and phosphatidic acid.

Uses of Phosphatidyl L-serine

The primary use of phosphatidyl l-serine in health supplements involves the support of cognitive functioning. Additional uses deal with memory, moods, and digestion.

Cognitive Function

Preliminary research shows that plant-based sources of phosphatidyl l-serine may help support cognitive functions such as attention span and language skills. This application is most common for older people.

Mood Support

Early research suggests that phosphatidyl l-serine may help to support low moods, especially in the elderly.

Memory Support

Phosphatidyl l-serine may help to support memory by improving absentmindedness and maintaining recall. This regimen often requires six to 12 weeks of regular use to obtain the best results.

Exercise Recovery

Phosphatidyl l-serine may help to maintain normal recovery after strenuous exercise, especially for athletes.

Signs You May Need Phosphatidyl L-serine

Age-related declines in cognitive function are generally the most significant signs that you may need phosphatidyl l-serine supplements. These signs primarily include problems with mood, memory, language skills and attention span.

Children who exhibit hyperactive behavior and have difficulty concentrating may also benefit from phosphatidyl l-serine, as well as athletes who experience muscle soreness.
