Phosphatidylserine Powder Wholesale
Time：2026-09-14Lixing Phosphatidylserine is a sunflower-derived nootropic ingredient designed for supplement manufacturers and wholesalers who need a reliable, high-purity bulk supply for cognitive health formulations.
Core Selling Points
≥50% Phosphatidylserine (PS) content – Reduces required raw material quantity by up to 20% compared to 40% PS powders, lowering final product costs per dose.Non-GMO sunflower lecithin source – Eliminates soy allergen concerns and supports clean-label positioning in markets where soy-derived PS is restricted.
Batch-to-batch HPLC quantification – Every lot is shipped with a Certificate of Analysis including real measured PS content, not just a reference range, ensuring consistent formulation across orders.
Heavy metals ≤ 0.5 ppm (lead, arsenic, mercury, cadmium) – Meets USP 232 guidelines, which is essential for export to North America and European Union markets.
Flexible packaging from 1 kg to 25 kg – Allows pilot batches at 1 kg scale and full production with double-layer polyethylene bags, with lead time of 7–10 days for standard quantities.

Applicable Scenarios
Nootropic powder blends – Manufacturers creating daily focus formulas can use PS as a base ingredient at 100 mg–300 mg per serving, paired with citicoline or L-theanine.Cognitive health capsules – Supplement brands targeting adults 40+ for memory support can directly incorporate PS with no taste modification needed.
Sports nutrition pre-workout – Athletic brands add 200 mg PS per serving to support stress response and training concentration, using the sunflower version to keep a gluten-free and soy-free label.
Keto/clean-label products – Formulators producing vegan or allergen-free lines use non-soy PS to meet consumer expectations for natural, non-GMO ingredients.
Contract manufacturing – CMOs can stock the 25 kg drum size and repackage into private-label blends while relying on the provided COA for regulatory fillings.
Common Questions
What is the minimum order quantity for wholesale?
The standard MOQ is 10 kg. For first-time trials, 1 kg samples are available at commercial grade price, which is credited to your larger order.
How do you guarantee the actual PS content is above 50%?
Third-party lab testing (using HPLC) is performed on each batch. The COA shows the exact percentage, and we can share prior batch reports upon request.
Can this PS powder be used in tablets directly?
Yes, the powder compresses well due to its phospholipid nature. If you need direct compression, we can granulate with silica or other excipients without incompatible additives.
Is the sunflower source verified non-GMO?
We provide an IP (Identity Preserved) certificate from the farmer to the extraction site. Annually audited by Valid-U, the document confirms no GMO contamination during growing or processing.
What is the shelf life and storage condition?
Shelf life is 24 months from the manufacturing date. Keep in a cool, dry place below 25°C, away from sunlight, and seal the bag after each use to prevent lipid oxidation.
Do you provide samples for stability testing?
Yes, we supply 100 g free samples with a courier cost. For stability studies requiring a 3-year period, we can provide batch retention samples from the same production lot.
How does this compare to soy-derived PS in terms of allergen risk?
Sunflower lecithin is inherently gluten-free and soy-free. The difference is absolute – soy-derived PS may carry traces of soy proteins that trigger cross-reactivity, while sunflower does not.
Are there any special import restrictions for this ingredient?
This PS is permitted in dietary supplements in the US (GRAS for certain uses), EU, and Australia. You will need a certificate of analysis and some countries require a free sale certificate which we can issue within 5 business days.
Why Choose This Supplier Over Others?
Most bulk PS on the marketplace comes from soy lecithin, which lowers costs but creates allergen warning labels. Lixing takes a different route: the entire production line uses sunflower lecithin, maintaining a full traceability from crop to powder without mixing batches. This means your brand can claim "soy-free" and "non-GMO" without spending on separate facility lines. Additionally, while many suppliers offer only one standard powder, Lixing provides custom particle sizing (e.g., 60–100 mesh for tablet pressing) and blends with binders at your request, which shortens your production timeline. The trade-off is a slightly higher unit price—usually 8–12% more than soy-based PS—but you remove allergen risk, reduce labeling restrictions, and obtain a cleaner label that supports a premium pricing strategy. If you serve health-conscious consumers, the total cost of ownership is lower because you avoid compatibility testing for soy-free claims and potential batch rejections from retailers. Lixing is not for free-spending buyers chasing the cheapest tonnage; it’s for manufacturers who value consistent quality, audited sourcing, and a long-term partner for cognitive health products.
