Overview
Phosphatidylserine (PS) is a naturally occurring phospholipid and a structural component of cell membranes. GreeneryBio supplies plant-derived PS as a high-purity, stable nutritional raw material for global dietary supplement, functional food and nutraceutical manufacturers.
Raw Material Source
This product uses non-GMO soybean lecithin from standardized planting bases as raw material, with multi-index screening. Plant-based PS avoids the zoonotic-contamination considerations of animal-derived material and suits clean-label and vegetarian positioning. Material is produced to FDA GRAS, EU and Chinese food-safety standards.
Extraction Process
We use an enzymatic transesterification + low-temperature supercritical CO₂ extraction process in place of traditional chemical extraction. Low-temperature, closed, sterile processing helps avoid denaturation of the active component and organic-solvent residues. Purification, catalytic synthesis, membrane filtration and sterile packaging support high purity and batch stability.
Active Ingredient Content
PS is supplied in four standard purity grades: 20%, 50%, 70%, 98%. The 20% / 50% grades are typical for conventional dietary supplements; the 70% / 98% high-purity grades are used in high-end functional preparations and nutraceutical intermediates. Batch-to-batch content is controlled within ±2% for consistency.
Key Active Compounds
Phosphatidylserine is the core component, accompanied by associated phospholipids:
- Phosphatidylserine — the primary characterized active and the basis of standardization.
- Phosphatidylethanolamine (PE) — an associated membrane phospholipid present in lower-purity grades.
- Unsaturated fatty acids — naturally associated lipid components.
Researched Activities
PS is among the more extensively studied phospholipids. The following reflect areas reported in published research and are provided for formulation context, not as product claims:
- Cognitive research — studied in research relating to memory and concentration endpoints.
- Stress / cortisol research — studied for its association with cortisol response in exercise and stress models.
- Sports nutrition research — investigated in relation to post-exercise recovery markers.
Application Areas
- Dietary supplements — brain-health and stress-management capsules and tablets; commonly combined with DHA or ginkgo extract.
- Functional foods & beverages — nutritional fortification of powders, beverages and cereals without altering flavor or texture.
- Sports nutrition — recovery-oriented formulations.
- Nutraceutical intermediates — high-purity (70–98%) grades for advanced formulation work.
