Phosphatidylserine(PS) with CAS 51446-62-9
What is Phosphatidylserine?
Phosphatidylserine (PS) is a naturally occurring phospholipid — a fatty substance that forms a critical structural component of cell membranes throughout the body, with the highest concentrations found in brain neurons.
As the primary anionic phospholipid in the inner leaflet of the plasma membrane, PS plays an indispensable role in cell signalling, neurotransmitter release, neuronal energy metabolism, and the regulation of apoptosis. Because dietary intake alone is insufficient to meet demand, PS is widely supplemented in nutraceutical and functional food formulas. Runtai Chemical supplies food-grade Phosphatidylserine powder. Each batch is HPLC-tested and accompanied by a full Certificate of Analysis (COA).
Runtai Chemical is a professional and reliable China manufacturer of Phosphatidylserine with CAS 51446-62-9 with higher purity and lower price. If you are interested in our Phosphatidylserine, PLS free to contact us for a free sample!
Product Advantages
- Cognitive Function & Memory: PS supplementation is clinically shown to support memory recall, learning capacity, concentration, and overall cognitive performance.
- Neuronal Energy Production: As a key component of neuronal membranes, PS facilitates glucose utilisation and enhances neurotransmitter synthesis, directly supporting brain energy metabolism.
- Stress Response Regulation: Studies demonstrate that PS blunts exercise- and psychological-stress-induced cortisol elevation, helping to normalise the HPA-axis stress response.
- Athletic Performance: PS is increasingly used in sports nutrition to reduce exercise-induced muscle damage, decrease DOMS, and improve endurance and recovery in high-intensity training.
- Antioxidant & Neuroprotective: PS exhibits antioxidant activity that helps protect neurons from free-radical damage, supporting long-term brain health and potentially slowing age-related cognitive decline.
