Bulk Supply Phosphatidylserine 51446-62-9 Powder
Time：2026-11-10What Is Bulk Supply Phosphatidylserine?
Bulk Supply Phosphatidylserine is a commercially available phospholipid compound (CAS No. 514-46-3) provided in powder or liquid form for dietary supplement manufacturers, nootropic formulators, and clinical nutrition brands that require a stable, high-purity raw material to support cognitive function, memory, and stress adaptation in their finished products.
Core Selling Points
Purity ≥ 50% verified by HPLC: Ensures consistent active ingredient concentration in every batch, allowing manufacturers to meet label claims without overage adjustments or costly re-testing.Sunflower lecithin-derived, non-GMO: Avoids soy allergens and GMO regulatory concerns across EU, US, and APAC markets, simplifying international product registration.
Production capacity of 500 kg per month: Supports mid-to-large-scale production runs with lead times of 7–10 business days, reducing inventory holding costs for contract manufacturers.
Batch-to-batch variability ≤ 2% RSD: Delivers reproducible formulation outcomes, which is directly correlated with capsule fill weight consistency and finished product dissolution uniformity.
Certified free of heavy metals (lead ≤ 0.1 ppm, arsenic ≤ 0.1 ppm) and residual solvents (≤ 10 ppm): Eliminates contamination-related rejection risks in finished products destined for regulated markets like Canada and the EU.

Applicable Scenarios
Nootropic formulation labs are sourcing a consistent phosphatidylserine raw material for a new memory-support capsule line; the centralized supplier data and stable batch composition reduce incoming material validation time from 3 weeks to 10 days.Contract manufacturers producing private-label stress-management supplements use this phosphatidylserine powder at 100 mg/serving to achieve a one-dose-per-day delivery format without compromising granulation flow properties.
Sports nutrition brands extending into focus-heavy pre-workout products rely on phosphatidylserine to coordinate with caffeine without instability issues observed in synthetic amino acid stacks.
Clinical research organizations preparing test articles for a double-blind cognitive trial specify this grade because the documented heavy metal results meet good laboratory practice (GLP) acceptance criteria with no additional purification step required.
Export-oriented supplement companies targeting European and Canadian markets use this sunflower-origin phosphatidylserine to avoid soy allergen labeling requirements that could limit retail acceptance.
Frequently Asked Questions
What is the minimum order quantity for bulk phosphatidylserine?
The minimum order quantity is 25 kg, which corresponds to one fiber drum; sample orders of 500 g are available for testing purposes.
How does sunflower-derived phosphatidylserine compare to soy-derived versions?
Sunflower-derived phosphatidylserine contains no soy protein residue and has a lower allergen profile; this allows cross-listing in soy-free product franchises across North America and Europe.
Can I request a certificate of analysis for each specific batch?
Yes, a unique COA is issued per batch and includes all parameters listed in the specification table, with exact values rather than reference ranges.
What is the lead time for a 100 kg order?
Production and third-party quality release require 10 business days, plus 3–5 days shipping depending on destination and incoterms.
Does this ingredient comply with FDA and EFSA regulations for use in dietary supplements?
The manufacturing facility follows cGMP per 21 CFR Part 111; the ingredient is intended for dietary supplement use and requires finished product registration per local jurisdiction guidelines.
How should the powder be stored to maintain stability?
Store the sealed drum below 25°C with relative humidity below 65%; under these conditions, the product retains ≥ 95% of its initial purity for 24 months.
Is phosphatidylserine suitable for use in vegetarian capsules?
Yes, this sunflower-derived phosphatidylserine powder contains no animal-derived components and is compatible with hydroxypropyl methylcellulose (HPMC) capsule lines.
Many suppliers source phosphatidylserine from bovine cortex or soy lecithin with purity variability between 20% and 45%, whereas the certified ≥ 50% HPLC purity in this sunflower-based powder, combined with measured bulk density and particle size assurance, provides a more direct formulation path with fewer downstream corrections. For manufacturers who prioritize batch consistency, documented heavy metal status, and non-GMO compliance across international markets, this Lixing supply option delivers a balance of technical rigor and regulatory preparedness that alternatives do not consistently match. It is best suited for mid-sized to enterprise supplement producers that have established quality control protocols and require verified raw material data for regulatory submissions without relying on armchair guidance from a sales representative.
