Phosphatidylserine 51446-62-9 Manufacturer Price
Time：2026-11-10The Phosphatidylserine (PS) powder manufactured by Lixing is a natural, soy-free phospholipid supplement designed for dietary supplement brands and adult users seeking evidence-backed support for age-related memory decline and elevated stress-related cortisol levels.
Core Selling Points
Purity ≥ 90% (HPLC Verified): Quantifies active phosphatidylserine content per gram, ensuring a 100–300 mg daily serving delivers the exact dosage used in clinical trials, without the filler found in 50%–70% commodity premixes.Sunflower-Derived Extraction: Sourced exclusively from non-GMO sunflower lecithin, eliminating the risk of soy allergens and phytoestrogen interactions, making it safe for sensitive populations and strict vegan or allergen-free labeling.
Particle Size (≥80% passing 80 mesh): Guarantees homogeneous blending with other excipients, reducing manufacturing variability and ensuring precise capsule weight distribution in high-speed production lines.
Rigorous Third-Party Safety Data: Certified lead content at ≤ 2 ppm and arsenic at ≤ 1 ppm per ICP-MS testing, meeting USP and EU contamination thresholds for daily long-term supplementation.

Application Scenarios
Aging Population (Ages 60+): For older adults noticing forgetfulness, a daily intake of 100 mg improves episodic memory performance within 8 weeks by replenishing cell membrane fluidity.High-Stress Professionals: For executives undergoing constant cognitive load, consuming 300 mg daily helps reduce elevated serum cortisol concentrations by up to 26%, preserving sustained attention during prolonged work hours.
Students in Exam Periods: For students preparing for postgraduate or professional exams, combining 200 mg phosphatidylserine with Omega-3 (DHA) accelerates neuroplasticity and improves complex information processing speed.
Sports Recovery Formula Designers: For formulators creating recovery drinks, the powder's neutral taste profile integrates cleanly into maltodextrin carriers to help athletes lower training-induced cortisol spikes.
Nutraceutical Startups (B2B): For supplement brands creating nootropic stacked capsules, this raw ingredient provides a certified allergen-free base with documented manufacturing lot-to-lot consistency.
Common FAQs
1. What dosage of phosphatidylserine is effective for reversing memory loss?
Clinical trials validate a daily intake of 100–300 mg per day. For memory support, target 100 mg three times daily. This specific ingredient offers 90% purity, meaning a 111 mg powder capsule delivers exactly 100 mg of active phosphatidylserine.
2. Is this raw material derived from soy or sunflower?
This specific Lixing raw material is sourced entirely from sunflower lecithin, not soy. This allows the final product to be labeled as safe to consume for those with soy allergies and reduces the risk of non-GMO cross-contamination issues.
3. Can I mix this powder directly into water and drink it?
No. The natural phospholipid is lipophilic and heavily clumps when mixed into an aqueous solution. It is best consumed as a pre-filled capsule, or homogenized thoroughly into a lipid-rich base like yogurt or a prepared smoothie emulsion.
4. How stable is this powder under standard warehouse temperatures?
Based on a 6-month accelerated stability test conducted at 40°C and 75% RH, the active content remains above 95% of its initial assay value. When stored sealed in the nitrogen-flushed bag, the practical shelf life extends to 24+ months.
5. Does this ingredient work effectively when combined with DHA?
Yes, phosphatidylserine works synergistically with DHA to improve neuronal membrane structure. Modern formulations typically pair this ingredient at a 1:1 weight ratio with algae-derived DHA for enhanced memory recall outcomes, showing superior results than either compound used alone.
6. Can this powder be safely given to children with attention deficit disorders?
Several meta-analyses indicate that a lower dosage of 50–200 mg daily improves learning symptoms in children with ADHD. However, since phosphatidylserine is a concentrated active ingredient, pediatric administration must be strictly restricted to licensed physician prescription levels.
7. What is the confirmed lead concentration in this specific batch?
The production batch specification strictly caps lead concentration at ≤ 2 ppm. In the most recent third-party heavy metal report, actual lead content was measured at 0.08 ppm, which falls well below global compliance limits for infant-safe categories.
While standard commodity phosphatidylserine often relies on inexpensive soybean extraction, yielding purities of only 50%–70%, the Lixing manufacturing process utilizes specialized cold-press sunflower technology, resulting in a validated ≥90% HPLC purity with precise batch-to-batch chromatographic reproducibility. This distinction eliminates the allergen and hormonal concerns associated with soy while offering dosage accuracy unattainable in diluted premixes. For precision-focused cognitive supplement brands and demanding adult consumers who require transparent sourcing, strict contaminant boundaries, and clinical-grade active concentrations, this ingredient represents a functionally robust alternative to generic and unpredictable lecithin extracts.
