Bulk Phosphatidylserine (PS) Powder | Premium Nootropic Lipid Matrix
Advanced Cognitive & Neurological Support by Xi'an Tihealth
As the global market for cognitive health and "Nootropic" supplements accelerates, formulators require highly stable, bioavailable, and allergen-compliant phospholipid sources. Xi'an Tihealth provides an industrial-grade Phosphatidylserine (PS) engineered specifically for premium brain-health and sports nutrition formulations.
Our Phosphatidylserine is enzymatically synthesized from premium plant-based lecithins using an advanced Phospholipase D (PLD) bio-conversion process. Available in both Soy-derived and Sunflower-derived (Allergen-Free) specifications, our PS accurately mirrors the phospholipids naturally abundant in human brain cell membranes. Offered in standardized purities ranging from 20% to 70%, it serves as a highly functional, flowable powder that is critical for cellular signal transduction, memory support capsules, and cortisol-modulating sports recovery blends
1. Formulation Edge: Why Choose Our Enzymatic PS?
Integrating functional lipids into dry powders or capsules often presents challenges with oxidation, poor flowability, and allergen compliance. Our specialized manufacturing eliminates these industrial bottlenecks:
- Allergen-Free Alternative (Sunflower PS): Traditional PS is derived from soy, which requires mandatory allergen declarations on consumer labels. We offer a premium Sunflower-derived PS that is 100% soy-free and Non-GMO, allowing nutraceutical brands to capture the lucrative clean-label and hypoallergenic market segments.
- Green Enzymatic Bio-Conversion: Rather than relying on harsh chemical extraction, we utilize Phospholipase D (PLD) to naturally convert the phosphatidylcholine in lecithin into phosphatidylserine. This "green chemistry" approach ensures zero harmful solvent residues and maintains the natural stereochemistry of the lipid.
- Customizable Purity Tiers (20% to 70%): We supply PS 20% (highly cost-effective, easily dispersible, ideal for dairy and powder blending) and PS 50% / 70% (ultra-concentrated, ideal for minimizing payload space in softgels and hard capsules).
2. Certificate of Analysis (Nutraceutical Grade TDS)
Strict parameter control over moisture and lipid oxidation is essential for shelf-life stability. Below is the analytical data sheet for our standard PS 50% Powder specification.
| Test Parameter | Specification Limit | Test Method / Standard |

3. Primary Functional Mechanisms (R&D Perspective)
Replacing non-compliant medical claims with scientifically validated cellular mechanisms, our Phosphatidylserine acts as a foundational active ingredient targeting:
Cognitive Function & Memory Support
PS is a major structural component of the neuronal membrane, maintaining cellular fluidity and permeability. It actively supports the release of neurotransmitters (like acetylcholine and dopamine) and the maintenance of synaptic receptors, making it a critical ingredient for supplements targeting age-related cognitive decline, focus, and memory recall.
Cortisol Modulation & Sports Recovery
In the realm of sports nutrition, intense physical exertion triggers a sharp increase in the stress hormone cortisol, leading to muscle catabolism. Clinical studies indicate that PS supplementation blunts the exercise-induced cortisol response, protecting muscle tissue, accelerating recovery, and helping athletes maintain a healthy anabolic state.
4. Targeted B2B Applications
- Dietary Supplements (Capsules & Softgels): The premier active lipid for "Nootropic" brain-health complexes, often formulated synergistically with DHA, Ginkgo Biloba, and Bacopa Monnieri. (PS 50% or 70% recommended).
- Functional Dairy & Infant Nutrition: Added to senior fortified milk powders and infant formulas to support brain development and nervous system health. (PS 20% recommended for easy blending).
- Sports Nutrition & E-Sports Supplements: Utilized in post-workout recovery powders to manage cortisol and in "gamer/e-sports" formulas to enhance focus and reaction times under stress.
- Functional Gummies: Easily incorporated into pectin or gelatin gummy matrices to deliver chewable cognitive support for both pediatric and adult demographics.
5. Secure Packaging & Global Logistics
Phospholipids are sensitive to oxidation when exposed to light and air. Operating under an ISO9001:2015 & GMP Quality Management System, we utilize vacuum-sealed, high-barrier packaging to ensure complete API stability during global transit.
| Order Volume | Packaging Type | Estimated Lead Time |
|---|---|---|
| 1kg - 24kg (R&D Samples) | Vacuum-sealed Opaque Aluminum Foil Bags | 3 - 5 Days (Air Express/FedEx) |
| 25kg - 500kg (Commercial Bulk) | 25kg Heavy-Duty Cardboard Drum with Double PE Liners | 7 - 10 Days (Air/Sea Freight) |
| > 500kg (Mass Production) | Custom Palletized Drums (MOQ supported) | 10 - 15 Days (Sea Freight / DDP Available) |
6. Formulation & Technical FAQ
It depends entirely on your target market and labeling requirements. Soy-derived PS is the industry standard and is more cost-effective. However, it may require an allergen declaration (Soy) on the product label. Sunflower-derived PS is slightly more premium but is 100% allergen-free and Non-GMO, making it the superior choice for "Clean-Label" brands and hypoallergenic product lines.
2：Which purity level (20%, 50%, 70%) is best for my product?
If you are formulating a dry powder blend, meal replacement shake, or dairy product, PS 20% is highly recommended. It is carried on maltodextrin/silica, providing excellent flowability, easy dispersion, and a lower cost per kilogram. If you are manufacturing softgels or hard capsules where physical space is limited, PS 50% or 70% provides a dense payload, allowing you to hit your dosage claims while keeping the capsule size small.
3：Can Phosphatidylserine powder dissolve to form a clear beverage?
No. Phosphatidylserine is a lipid (fat-soluble compound). While our powder disperses very well in water to form stable emulsions or liposomal suspensions (appearing milky or cloudy), it will not dissolve into a transparent, clear solution. Formulators designing clear RTD beverages should consider alternative delivery systems or specialized nano-emulsion technologies.
