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 Xtend-Life 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.
The primary uses of phosphatidyl l-serine in health supplements involves the support of cognitive functioning. Additional uses deal with memory, moods and digestion.
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.
Early research suggests that phosphatidyl l-serine may help to support against low moods, especially in the elderly.
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.
Phosphatidyl l-serine may help to maintain normal recovery after strenuous exercise, especially for athletes.
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.
As you know, our bodies don’t like stress. Whether it’s physical stress, like a dog chasing you or emotional stress, such as presenting a speech in front of a large group of people, our bodies release signalling molecules called inflammatory cytok...
