Description

Phosphatidylserine is a vital phospholipid and an essential component of cell membranes, particularly in the brain. Its primary commercial value lies in its role as a key ingredient for cognitive health and neurological support in dietary supplements and functional foods. This high-purity material is critical for manufacturers in the nutraceutical, pharmaceutical, and cosmeceutical industries seeking to develop evidence-based formulations. We supply Phosphatidylserine CAS NO 51446-62-9 to meet the stringent quality demands of global B2B customers.

Application

• Dietary Supplements & Nootropics: Core active ingredient in formulations targeting memory enhancement, cognitive function, stress reduction, and mood support.
• Functional Foods & Beverages: Fortification of health drinks, nutritional bars, and dairy products to add cognitive health benefits.
• Pharmaceuticals: Used in research and development of drugs for age-related cognitive decline, Alzheimer's disease, and other neurological disorders.
• Cosmeceuticals & Skincare: Incorporated into anti-aging creams and serums for its purported skin barrier repair and cell membrane-stabilizing properties.
• Sports Nutrition: Added to products aimed at reducing exercise-induced cortisol levels and supporting post-exercise recovery.
• Infant Formula: Used as a structural phospholipid to mimic the nutritional profile of human breast milk for optimal brain development.
• Veterinary Nutrition: Component in specialty pet foods and supplements for senior pet cognitive health.
• Cell Culture & Research: Essential lipid for neuroscience research, membrane studies, and in vitro cell culture applications.
