Phosphatidylserine 51446-62-9 Supply price
Time：2026-11-11Phosphatidylserine, supplied by Lixing, is a sunflower-derived phospholipid powder for dietary supplement and functional beverage manufacturers, solving the need for a high-purity, allergen-free raw material to support memory and cognitive products.
Core Strengths
Content ≥90.0% measured by HPLC — one kilogram delivers 900 g of active phosphatidylserine, allowing a 100 mg per-serving dosage with a smaller fill weight and reduced excipient cost.Sunflower-derived and non-GMO — the powder is extracted from sunflower lecithin and contains no soy or gluten, which removes common allergen declarations and supports clean-label positioning.
Batch-specific Certificate of Analysis (COA) — every lot lists content, heavy metals, residual solvents, and microbial counts, making incoming quality checks and supplier qualification faster for buyers.
36-month shelf life — nitrogen-padded 25 kg drums protect the powder at 15–25°C, reducing the risk of expiry during long-distance shipping or warehousing.
Third-party laboratory verification — each batch is independently verified for HPLC purity, with the report attached to the COA for the buyer’s quality department.

Typical Use Scenarios
Memory supplement brands — formulate 100 mg phosphatidylserine per hard-gel capsule; the high concentration cuts capsule fill weight and lowers total production cost.Functional beverage manufacturers — add the powder to dry beverage mixes aimed at daily cognitive support; sunflower lecithin helps dispersibility under simple agitation.
Sports nutrition companies — use phosphatidylserine in recovery or stress-management formulas, where human intervention trials guide dosage at 100–400 mg per day.
Private-label importers — source the 90% powder for white-label memory supplements, relying on the COA, non-GMO declaration, and origin documents for customs registration.
Frequently Asked Questions
What is the recommended daily intake of phosphatidylserine?
Published human studies on cognitive outcomes have used 100–300 mg per day. For the 90.0% powder this equals 111–334 mg of bulk material. Formulators should confirm that the intended use level is compliant with local food supplement regulations. Final dosage must be verified by stability and safety evaluation in the finished product.
Does phosphatidylserine help with memory loss in older adults?
A 2010 systematic review by Kato-Kataoka reported benefits on memory in elderly subjects with cognitive decline after 100–400 mg/day supplementation. Trial heterogeneity was noted, so consumer-facing claims require their own qualified evidence and legal review. Source: PubMed-indexed review. Consult the full text for inclusion criteria and effect size.
Is this powder suitable for vegetarian and vegan products?
Yes. The raw material is sunflower lecithin, and the enzyme used for enrichment is of microbial origin and removed during processing. No animal-derived processing aids remain in the final powder, according to the batch records of the quality management system.
How do I store the product after opening the drum?
Reseal the inner bag immediately after sampling and store in the original drum at 15–25°C, away from light, heat, and water. Under recommended conditions, the material remains within specification for at least 12 months after opening, based on stability study data.
What certificates are provided with export shipments?
Each shipment includes a Certificate of Analysis, Certificate of Origin, Non-GMO Declaration, and MSDS. A phytosanitary certificate is issued when the destination country requires it. Buyers should verify the required format with their forwarding agent to avoid customs delays. Allow 5 working days for the phytosanitary request.
Will I get samples before a bulk order?
Yes. A 100 g evaluation sample is available with the buyer covering freight charges. Samples ship with the batch COA and Non-GMO Declaration. Once the bulk order is placed, the sample cost is deducted from the invoice. A custom sample amount can be sent after the first order.
How It Differs from Similar Ingredients
Several suppliers offer phosphatidylserine in 20% or 50% concentrations, usually blended with soy lecithin. Lixing’s 90% sunflower-derived version differentiates through a measurable lower allergen profile, a higher proportion of active phosphatidylserine per capsule, and a COA package that lists solvent residue and heavy-metal results for each lot. It suits importers and manufacturers that prefer an audit-ready, clean-label ingredient rather than a diluted bulk blend.
