Phosphatidylserine Powder Factory Direct Sales
Time：2026-09-20Product Overview
Lixing Phosphatidylserine is a GMP-certified, ≥98% pure bulk powder for dietary supplement manufacturers who need a third-party-validated cognitive health ingredient to combat memory decline, poor focus, and stress-related mental fatigue.
Key Benefits
≥98% HPLC purity – Provides accurate PS content per capsule, enabling precise dosing without excess fillers and stable batch-to-batch potency.Heavy metals below USP limits – Lead ≤0.5 ppm, arsenic ≤0.5 ppm, cadmium ≤0.5 ppm, mercury ≤0.5 ppm, so finished products can make clean-label safety claims.
Factory-direct procurement – Eliminates intermediated margins, reducing raw material cost per kilogram by an average of 25–30% compared to distributor pricing in comparable high-purity grades.
Customizable particle size (80–200 mesh) – Allows formulators to optimize flowability and mixing for capsules, tablets, or premixes, without outsourcing additional processing.

Use Cases
A supplement manufacturer formulating a memory-support capsule can use this powder to deliver 100 mg PS per serving, backed by COA.An R&D team developing a children’s omega-3 + PS blend can incorporate the fine mesh version for smooth mixing in flavored chewables.
A private-label brand launching an aging-care product line can rely on factory-direct lots with stable heavy metal compliance and full documentation.
A contract manufacturer producing stress-relief tablets can use the powder directly in a granulation process without requiring additional purification.
Frequently Asked Questions
What is phosphatidylserine good for?
Phosphatidylserine is a phospholipid that supports cell membrane integrity and signal transduction in the brain. Studies indicate it may help maintain memory, focus, and mental clarity in aging adults and people under high stress. It is commonly used in formulations targeting memory decline and school-age learning support, with clinical dosing typically 100–300 mg per day.
Is phosphatidylserine safe with other supplements?
Phosphatidylserine is generally well-tolerated and compatible with omega-3, B-complex vitamins, and Ginkgo biloba. No known negative interactions exist for healthy adults. Still, consult a healthcare provider before combining it with blood thinners or if you are pregnant, nursing, or have a pre-existing condition.
How many milligrams of phosphatidylserine per day?
Clinical research commonly uses 100–300 mg per day, divided in two or three servings. Most commercial supplements provide 100 mg per capsule. The appropriate dose depends on age, body weight, and purpose, so follow the product label or a qualified physician’s recommendation.
Do you offer free samples for testing?
Yes, we provide a 50 g sample packet for evaluation. The sample includes the batch COA and technical datasheet. Shipping cost depends on the destination, and you can request it through the company inquiry form. This helps verify purity and flowability before placing a full order.
What is the minimum order quantity for factory direct powder?
The standard minimum order quantity is 25 kg per lot, equal to one fiber drum. For R&D trials, we may accept a smaller order when combined with other ingredients. Custom MOQs are available quarterly. Contact our sales team for current terms and logistics.
Can you provide a certificate of analysis for each batch?
Yes, each batch ships with a certificate of analysis covering assay, heavy metals, microbial limits, and residual solvents. The COA is generated after third-party laboratory testing and is sent for approval before shipment. You can also request endotoxin and allergen data if needed.
Does this powder dissolve in water?
Phosphatidylserine is lipophilic and does not fully dissolve in water. It disperses when mixed with oil or emulsifiers. For beverage or gummy applications, we recommend using the microencapsulated or premix form to obtain stable suspension and acceptable taste.
How should I store the bulk powder?
Store the unopened drum in a cool, dry, dark place below 25°C. After opening, reseal tightly after each use. Avoid direct sunlight and humidity. Under proper storage, shelf life is 24 months from manufacture date. Keep away from heat sources and strong odors.
Why Choose Factory-Direct Lixing
Most phosphatidylserine suppliers offer a single standard grade or rely on multi-tier distribution. Lixing produces directly in a GMP facility and supplies only tested, high-purity material with transparent documentation. This approach suits supplement brands and contract manufacturers that prioritize compliance, cost stability, and production flexibility. If you need a partner that can scale with you and provide rapid technical support, this factory-direct option is a strong match.
