What Is Phosphatidylserine 50%?

The product is a phospholipid concentrate, made by enzymatic transphosphatidylation of high quality lecithin with L-serine. The result is a standardized powder that is precisely 50% active phosphatidylserine.

It is a significant structural component of cell membranes, notably in brain tissue, and enables communication between neurons. The 50% concentration is the industry gold standard, giving you excellent potency without the additional bulk.

This approach addresses frequent formulation issues. You get an efficient dose in smaller capsules, higher resistance to oxidation and clean sensory profiles. If you are formulating nootropic stacks or fortified food this concentration is a happy medium between material efficiency and theraputic potency.

Applications Across Industries

Nootropic Nutritional Supplements

Phosphatidylserine 50% is the active ingredient in capsules and tablets for brain health. Formulators generally use daily doses of 200-600mg to aid memory, focus and age related cognitive maintenance.

High concentration means you can make successful single-ingredient products or combine with other nootropics without the limits of capsule size.

Functional Food & Beverage Enrichment

Phosphatidylserine fortification benefits premium milk powders, nutritional snacks and specialist dairy products This 50% concentration provides important doses (100-300mg) without sacrificing texture, taste or stability.

Our powder is highly compatible with existing production methods. You can add brain health claims to items for students, professionals and elders.

Senior Pet Feeding

Our substance is used by veterinary formulators to combat Canine Cognitive Dysfunction. High purity assures efficacy in tiny dose treats and soft chews, even under high shear extrusion production conditions.

As pets get older, owners are looking more and more for help for their cognition. This is an emerging business potential.

Cosmetic & Skincare Formulations 

Phosphatidylserine is well known for internal use, but its cell membrane support abilities can also be helpful in topical applications. Stable in cosmetic formulations, it helps to improve skin barrier function and cell health.

Quality Control & Testing

For each batch we follow a strict quality assurance protocol:

Active Content Verification: HPLC coupled with Evaporative Light Scattering Detection (ELSD) validates the ≥50% phosphatidylserine specification.

Heavy Metal Screening: using the latest testing methods we can identify lead, arsenic, cadmium and mercury at trace levels to meet the most stringent international standards.

Microbial Safety: Each lot is tested for pathogens including E. coli, Salmonella and total plate count to ensure food grade safety.

Oxidation Testing : Acid Value and Peroxide Value Testing Prevents Degradation, So Your Products Stay Potent For Their Entire Shelf-Life.

GMO & Allergen Testing: We can use PCR and ELISA to confirm that your product is non-GMO and screen for the presence of potential allergens so you can label accurately.

We have an in-house laboratory with HPLC, GC, TLC, UV-Vis spectrophotometers and moisture analyzers. Third party testing services available on request. Certificates of Analysis are provided with each shipment.

FAQ

Q: How do I choose between soy-based and sunflower-based product?

A: Sunflower-derived product is ideal for allergen-free and non-GMO labeling, appealing to health-conscious consumers. Soy-based options remain cost-effective for standard formulations without specific allergen restrictions. We can help you evaluate based on your target market and positioning.

Q: Is the product heat stable for functional baking applications?

A: The ingredient remains stable at moderate temperatures, but prolonged exposure above 120°C may cause degradation. We recommend incorporating it post-thermal processing or into no-bake formulations for optimal activity retention.

Q: Why does the color vary slightly between batches?

A: Natural variations from light yellow to tan occur due to the botanical lecithin source and enzymatic processing conditions. These aesthetic differences don't affect the guaranteed 50% active assay or functionality in your products.

Q: What is the recommended dosage for cognitive support claims?

A: Clinical studies typically use 100mg of pure phosphatidylserine three times daily (300mg total active). With our 50% concentration, this translates to 600mg of powder daily. We recommend consulting regulatory guidelines in your specific market for claim substantiation.

Q: Does your product comply with California Prop 65 requirements?

A: Yes. Our high-purity extraction process ensures heavy metal levels, particularly lead (<0.5 ppm), fall well within California Prop 65 safe harbor limits. Documentation is available upon request.
