Products Description
Soybean Phosphatidylserine Powder 50% is a standardized phospholipid ingredient produced from soybean lecithin through a controlled enzymatic conversion process with L-serine. Designed for dietary supplement and functional nutrition manufacturers, this soy-derived phosphatidylserine powder combines a defined 50% phosphatidylserine specification with controlled powder processing and documented quality parameters.
The production process includes soybean lecithin purification, phospholipase-mediated enzymatic catalysis with L-serine, further purification, vacuum drying, crushing, and 60-mesh sieving. The process also incorporates magnetic separation and X-ray inspection as part of the documented foreign-material control system.
The supplied COA shows a tested phosphatidylserine content of 51.3% on a dry basis, with 1.0% moisture and a peroxide value of 0 meq/kg. The product is supplied as a light-yellow powder with a characteristic aroma and no peculiar smell, making it a practical phosphatidylserine raw material for capsules, tablets, powder blends, and other dry-format nutritional products.
A More Controlled Approach to Soy Phosphatidylserine Production
For buyers sourcing soy phosphatidylserine powder, the source of the phospholipid is only one part of the purchasing decision. The conversion method, purification steps, drying conditions, particle processing, oxidation status, and foreign-material controls all contribute to the overall raw-material profile.
This product starts with soy lecithin and uses L-serine in a phospholipase-mediated enzymatic catalysis step to produce phosphatidylserine. After the conversion stage, the material undergoes further purification before vacuum drying, crushing, and controlled sieving.
This process-based approach gives buyers more than a botanical source statement. It provides a defined manufacturing route that can be reviewed alongside the product specification and batch COA when conducting supplier qualification.
For companies looking for phosphatidylserine 50% bulk, this standardized grade provides a practical balance between defined active content and flexible formulation use.
Product Highlights
Standardized 50% Phosphatidylserine
The product is specified at 50% phosphatidylserine. The supplied COA recorded 51.3% phosphatidylserine on a dry basis for the tested batch, providing a clear analytical reference for formulation and purchasing calculations.
Soy-Derived Phospholipid Ingredient
Soybean lecithin is used as the starting phospholipid material. This makes the ingredient suitable for manufacturers specifically searching for a soy-derived phosphatidylserine ingredient rather than an unspecified phospholipid source.
Controlled Moisture
The moisture specification is ≤2.0%, while the tested batch showed 1.0% moisture. Controlled moisture is an important consideration for manufacturers purchasing and handling powdered phospholipid ingredients.
Low Oxidation Indicator
The peroxide value specification is ≤10.0 meq/kg. The supplied batch recorded a peroxide value of 0 meq/kg, providing a useful batch-level quality indicator for an oxidation-sensitive phospholipid raw material.
Defined Powder Processing
After vacuum drying, the material is crushed and passed through a 60-mesh sieve. This creates a defined powder-processing step for downstream blending and filling applications.
Documented Foreign-Material Control
The process flowchart includes a magnetic separator with a specified magnetic strength of ≥9,000 Gauss, together with an X-Ray machine identified as a CCP. These steps form part of the documented physical foreign-material control process.
Manufacturing Process
The documented production route for this soybean phosphatidylserine powder includes several controlled stages:
Soy Lecithin → Purification → Phospholipase Enzymatic Catalysis + L-Serine → Purification → Vacuum Drying → Crushing → 60-Mesh Sieving → Magnetic Separation / X-Ray Inspection → Inner Packaging → Outer Packaging → Warehousing
The process begins with soybean lecithin and introduces L-serine during the enzymatic catalysis stage. After purification and vacuum drying, the dried material is processed into powder and screened through a 60-mesh sieve.
The documented process also includes physical control measures before packaging. Magnetic separation is performed using equipment specified at ≥9,000 Gauss, while X-Ray inspection is identified as a critical control point.
This combination of enzymatic conversion, purification, controlled drying, particle processing, and physical inspection provides a more transparent basis for evaluating the ingredient as a commercial phosphatidylserine raw material.

Applications of Soybean Phosphatidylserine Powder
Dietary Supplement Formulations
Phosphatidylserine for dietary supplements can be incorporated into nutritional formulas where a standardized phosphatidylserine ingredient is required. The 50% specification allows manufacturers to calculate raw-material usage according to their finished-product target.
Phosphatidylserine Capsules
The powder format is suitable for development of phosphatidylserine capsules, either as a single active ingredient or as part of a multi-ingredient nutritional formula.
Tablets and Powder Blends
For tablet and powdered supplement manufacturers, phosphatidylserine powder can be combined with other nutritional ingredients during dry blending. Final processing parameters should be established according to the specific formulation and manufacturing equipment.
Functional Nutrition Products
The ingredient can be considered for powdered nutritional products, sachets, premixes, and other dry-format functional nutrition applications requiring a defined phosphatidylserine content.
Cognitive Wellness and Healthy-Aging Formulas
Phosphatidylserine is commonly used as a specialized phospholipid ingredient in nutritional products positioned around cognitive wellness and healthy aging. Specific product claims and marketing language should be evaluated according to the regulatory requirements of the destination market.
Why Choose a 50% Soybean Phosphatidylserine Grade?
Not every supplement formula requires the highest available PS concentration. A 50% phosphatidylserine powder can provide a useful option for manufacturers balancing active concentration, formulation design, and raw-material cost.
A standardized assay also makes it easier for procurement and R&D teams to establish internal specifications. Instead of working with an undefined phospholipid concentrate, formulators can calculate their ingredient input around a clearly stated phosphatidylserine content.
For B2B buyers, the more important question is therefore not simply "What is the PS percentage?" but rather:
Can the supplier provide a consistent specification, traceable batch documentation, a defined manufacturing process, and practical support from sampling through export?
That is the purchasing framework this product is designed to support.
Why Choose Us for Soybean Phosphatidylserine?
Choosing a soybean phosphatidylserine supplier is about more than finding a product with the right assay. For international buyers, supplier reliability also depends on how efficiently a company can handle samples, technical documentation, specifications, communication, and export logistics.
1. Product Information Built Around Real Batch Data
We provide product specifications supported by actual batch documentation rather than relying only on a general product description. For this phosphatidylserine 50% powder, customers can review the available COA together with the documented production flow before moving forward with procurement.
This gives purchasing and quality teams a clearer basis for supplier evaluation.
2. Small Samples Before Bulk Orders
We understand that supplement manufacturers normally need to evaluate an ingredient before committing to a large order.

R&D formulation trials
Powder handling evaluation
Ingredient compatibility testing
Preliminary quality assessment
Internal supplier approval
This allows customers to assess the material first and make a bulk purchasing decision based on their own formulation requirements.
3. Familiar with International Export Procedures
For overseas buyers, a raw-material order involves more than production. Product documentation, packaging information, shipping arrangements, customs requirements, and communication between different teams can all affect the purchasing process.
Our team has experience working with international customers and coordinating the practical steps involved in bulk ingredient export, helping reduce unnecessary communication between the buyer, supplier, logistics provider, and documentation teams.
4. Experience Serving Customers in 30+ Countries
Our ingredients have been exported to 30+ countries, giving us practical experience with different purchasing processes, customer requirements, documentation expectations, and shipment arrangements.
For a buyer looking for a phosphatidylserine supplier for international distribution, this experience can be particularly useful when the project involves more than a one-time sample order.
5. Technical Communication for B2B R&D and Procurement
We understand that different departments ask different questions.
R&D teams may focus on assay, powder characteristics, processing compatibility, and formulation requirements. Procurement teams may focus on MOQ, packaging, lead time, and price. Quality teams may need COA and process documentation, while logistics teams focus on shipping and export documents.
We aim to provide information in a way that supports the entire purchasing process rather than simply sending a product quotation.
6. Flexible Support from Sample to Bulk Supply
Whether you are developing a new phosphatidylserine supplement, replacing an existing supplier, testing a new specification, or preparing for recurring bulk purchasing, we can support different stages of the sourcing process.
Our goal is to build a practical supply relationship around your actual requirements - from the first sample and technical evaluation to commercial orders and repeat shipments.
7. Clear Communication, Practical Problem Solving
Ingredient sourcing does not always follow a fixed process. Specifications may change, documentation may need to be adjusted for a destination market, packaging requirements may differ, or an R&D team may need additional information during testing.
We focus on direct communication and practical coordination so that these issues can be addressed efficiently during the purchasing process.
