Phosphatidylserine, also known as compound nerve acid. Referred to as PS, extracted from the residue of natural soybean oil extraction. Is a cell membrane active substance, especially in brain cells. Its main function is to improve the function of nerve cells, regulate the conduction of nerve impulses and improve the memory function of the brain. Due to its strong lipophilicity, it can rapidly enter the brain through the blood-brain barrier after absorption, relieve vascular smooth muscle cells and increase the brain The role of blood supply.

Phosphatidylserine is processed into capsules, tablets and powders for students, office workers and seniors to improve memory, concentration and stress resistance, as well as slow cognitive decline in the elderly. It works better when mixed with DHA, GABA or magnesium glycinate.
As an authorized new food raw material, phosphatidylserine can be added to milk, yogurt, cereal bars, meal replacement powders and brain health drinks to supplement cognitive nutrients.
In sports nutrition formulas, phosphatidylserine lowers cortisol levels after exercise, relieves inflammation and speeds up physical recovery for athletes and fitness lovers.
Adjacent nutrient for mild cognitive impairment and mood imbalance; also serves as emulsifier and liposomal drug delivery carrier.
Moisturizing, anti-oxidation and barrier-repair ingredient for serums, creams and masks, targeting stress-induced dullness and fine lines.
Pet cognitive supplements, special medical foods and premium nootropic blends.

Phosphatidylserine (PS) is a cell membrane active substance, highly concentrated in brain cells. It is extracted from the residue of natural soybean oil extraction, making it a natural and effective ingredient for cognitive support.
We offer multiple variations including Sunflower Lecithin, Phosphatidylcholine (20%-90%), and Phosphatidylserine in concentrations ranging from 10% to 80%. Our standard quality specification guarantees an L-α-Phosphatidyl-L-serine content of over 20% by HPLC-ELSD.
Yes, our Phosphatidylserine conforms to strict Non-GMO standards. It is tested in accordance with standard SN/T 1195-2003 to ensure absolute quality and safety compliance.
Phosphatidylserine is widely used in dietary supplements (capsules, tablets, and powders), functional food and dairy products, sports nutrition to manage post-exercise cortisol levels, clinical auxiliary products, and neurocosmetics for skin-barrier repair.
For smaller volumes (1kg), we package with double plastic bags inside, an aluminum foil bag, and an outer box. Bulk orders (10kg, 25kg or more) are packed in drums or cartons. Delivery is available globally via Express (EMS, DHL, UPS, FedEx), Air, or Sea, depending on order size and destination.
