Phosphatidylserine
Brief Introduction:
Phosphatidylserine, also known as 1,2-Diacyl-sn-glycero-3-phospho-L-serine or L-α-Phosphatidyl-L-serine, abbreviated as PS, is an important phospholipid that is widely present in biological membranes, especially in animal cell membranes. It is one of the important components of brain cell membranes and can improve brain function, help concentrate attention and repair brain damage, especially playing an important regulatory role in the brain's memory and emotional stability.
Phosphatidylserine can also be extracted from the residue of natural soybean oil extraction.
The Main Functions of Phosphatidylserine (PS):
1. Improve Brain Function and Improve Alzheimer's Disease:
With age, phosphatidylserine and other important brain chemicals will gradually decrease, leading to weakened memory and cognition. Supplementing phosphatidylserine can increase the number of brain spikes, the fluidity of brain cell membranes, and promote glucose metabolism in brain cells, making brain cells more active. Italy, Scandinavia and other European countries widely use phosphatidylserine supplements to treat dementia and memory loss caused by aging.
2. Helps Repair Brain Damage:
Phosphatidylserine is one of the main components of brain nerves, it has the function of nourishing and activating the activity of various enzymes in the brain, slowing down the reduction of neurotransmitters, and helping to repair and renew damaged brain cells and remove harmful substances.
3. Relieve Stress:
Phosphatidylserine can promote recovery from mental fatigue and balance emotions: Many studies have shown that phosphatidylserine can significantly reduce the level of excessive stress hormones in people with work-related stress, reduce stress, relieve brain fatigue, promote concentration, improve alertness and memory, and relieve negative emotions.
4. Phosphatidylserine (PS) can improve the language memory ability of normal adults.

Phosphatidylserine is Suitable for the Following Groups of People:
1. Pregnant Women:
Supplementing phosphatidylserine in moderation during pregnancy can not only work synergistically with DHA, promote mutual absorption, and promote the intellectual development of the fetus, but also effectively relieve tension during pregnancy, reduce stress, and reduce the occurrence of postpartum depression.
2. Fetus & Infants:
Phospholipids are essential for the neural development of fetuses and infants, the human brain has about 15 billion cells, 70% of which have been formed in the mother's body, so the infant period is the most critical period for the formation and development of the brain. Phospholipids can promote the growth and development of the brain's nervous system and brain volume, therefore, the US Food and Drug Administration stipulates that phospholipids must be added to infant formula. The fetus has a huge demand for phospholipids during its formation and development, and the amount of phospholipids required for brain development is 2 to 3 times that of other tissues.
3. Teenagers:
Due to the pressure of studying and taking exams, the brain of teenagers is often in a high-speed operation state, and the amount of neurotransmitters (acetylcholine) consumed increases greatly. If they can not be supplemented in time and in sufficient quantity, it will inevitably affect the normal function of the brain, causing forgetfulness and inattention.
4. Middle-aged & Elderly People:
When people reach middle age, their brain function gradually declines. As they enter old age, brain cells gradually die, and the content of acetylcholine, a neurotransmitter, decreases, leading to slow reactions, slow movements, memory loss, and even Alzheimer's disease.
Applications of Phosphatidylserine in Different Fields:
1. Drug Delivery System:
Liposome Carrier: In the pharmaceutical field, phosphatidylserine is used as a component of liposomes to help target the delivery of anticancer drugs or gene therapy substances and improve drug absorption efficiency.
2. Food & Beverage:
① Solid food: Generally speaking, phosphatidylserine is more stable when added to solid food, such as fortified choline cereal;
② Beverage: Since phosphatidylserine is an active substance, it is suitable for addition to functional beverages;
③ Milk: The added phosphatidylserine can enter the fat droplets of milk, avoiding the hydrolysis reaction of phosphatidylserine and having good stability;
④ Yogurt: After pasteurization, the drinking yogurt fortified with phosphatidylserine has no content loss during the entire validity period, which shows that phosphatidylserine has strong stability in yogurt;
⑤ Milk powder: Phosphatidylserine can be added to adult milk powder and elderly milk powder, and has strong stability;
⑥ Health products: Phosphatidylserine can also be used to add to other health products.
3. Anti-aging and Skin Health:
① Cell membrane repair: As an antioxidant, phosphatidylserine may delay cell aging, especially for the stability of skin cell membranes.
② Application in skin care products: Topical skin care products containing phosphatidylserine may enhance skin barrier function, reduce water loss, and improve dry or sensitive skin.
