What is PS (phosphatidylserine)?
Phosphatidylserine is extracted from natural soybeans-also known as serine phospholipids, diacylglycerol acyl phosphatidylserine, is a unique bimolecular phospholipid-containing substance that is itself soluble in both water and fat, and is also a class of ubiquitous phospholipids, usually located in the inner layer of cell membranes, phosphoglycerides of phosphate compounds, which are one of the cell membrane components and are associated with a range of membrane functions.
Especially in the human nervous system, it is one of the important components of the cell membrane of the brain and plays an important role in regulating various functions of the brain (especially the memory and emotional stability of the brain), such as it affects the fluidity and permeability of the cell membrane, and activates the metabolism and synthesis of various enzymes, improves the function of nerve cells, regulates the conduction of nerve impulses, and enhances the memory function of the brain.
What is the role of PS (phosphatidylserine)?
1. Enhances memory
In Japan, the United States and other countries, it is believed that supplementation with phosphatidylserine can increase the number of brain synapses and the fluidity of brain cell membranes, and promote glucose metabolism in brain cells, thus making brain cells more active, enabling people to focus more, and improving brain alertness and memory levels. An Israeli study found that phosphatidylserine supplementation improved memory cognition in volunteers, while a study by the Center for Nutrition and Food Safety at the Third Military Medical University in China also showed that phosphatidylserine significantly improved and enhanced memory in students.
2. Stress relief
As one of the main components of the nerves in the brain, phosphatidylserine can nourish and activate the activity of various enzymes in the brain, helping to repair and renew damaged cells in the brain. This unique effect helps to reduce excessive levels of stress hormones in the body of brain workers, reducing stress and relieving brain fatigue and bad mood. Nutrition experts point out that phosphatidylserine nutrients are mainly extracted from soybean phospholipids, a rare and essential component of soybean phospholipids containing only 0.5%. The usual increase in the supplementation of soy is beneficial to enhance and improve memory, but it is difficult to achieve a significant improvement in memory in the short term just by consuming soy, and for those who need it, the nutrient supplementation can be done appropriately. Clinical trials have shown that therapeutic benefits in terms of intellectual function can be obtained by consuming 200 to 500 mg of phosphatidylserine daily.
Progress of "PS" in various countries, and the recommended amount in China
Korea: In May 2006, the Korea Food and Drug Agency (KFDA) allowed products containing phosphatidylserine to be highlighted and advertised as having the function of "preventing cognitive impairment in the elderly".
Japan: On February 5, 2010, PS (phosphatidylserine) was included in the list of foods (not drugs) to which the Japanese Food and Drug Administration (FDA) belongs, following an individual review of food additives.
U.S.A.: In October 2006, the U.S. Food and Drug Administration approved phosphatidylserine as a functional food material for nutritional fortification in yogurt, milk powder, bread and other foods through GRAS (Generally Recognized as Safe).
EU: In October 2009, the application for phospholipids rich in soy phosphatidylserine was approved as a new resource food.
China: In November 2010, phosphatidylserine was approved by the Ministry of Health as a new resource food, which is mainly extracted and purified from natural soybean oil extraction by-products.
