Time：2026-10-27Phosphatidylserine Price: A Data-Focused Look at Lixing Phosphatidylserine Powder
Lixing Phosphatidylserine is a non-GMO, sunflower-derived phospholipid powder standardized to 20% L-α-phosphatidylserine, designed for adults who want a measurable PS dose for cognitive, memory, or stress support without caffeine or animal-derived ingredients.
Core Selling Points
20% PS assay verified by HPLC – Each 1 g serving provides 200 mg of phosphatidylserine, a level consistent with cognitive-support research. No guesswork on active ingredient.Sunflower lecithin source – Avoids soy allergens and bovine-brain material, which matters for vegan buyers and formulators with clean-label requirements.
80-mesh fine powder – Disperses quickly in cold water, juice, or smoothies, and also mixes cleanly into capsule or sachet production.
Batch-specific COA documentation – Residual solvents, heavy metals, and microbial counts are disclosed per batch, so buyers can verify quality instead of relying on the label.

Suitable Use Cases
Structured work sessions: A software developer adds 1 g PS to lukewarm water before a 4-hour coding block to maintain focus without caffeine.Exam preparation: A student uses 200 mg PS with breakfast to support recall during high-load study periods.
Age-related forgetfulness: Adults over 60 mix 0.5–1 g into soup or juice to maintain memory-related phospholipid levels.
Post-exercise recovery: Athletes use 200 mg PS after intense training to support normal cortisol response, especially in overtraining periods.
Supplement formulation: Manufacturers use this 20% PS powder as a raw input for capsules, stick packs, or functional drinks.
Common Questions
Should I pay more for sunflower-derived phosphatidylserine?
Not necessarily. Sunflower PS is useful if you have soy allergy, prefer vegan sourcing, or want to avoid bovine-derived materials. Soy-based PS can perform well if it meets the same HPLC purity. Compare cost per milligram of active PS, not per gram of powder.
How do I compare phosphatidylserine price per active gram?
Divide the batch price by the actual PS content. For example, 1 kg of 20% PS contains 200 g of pure phosphatidylserine. That number tells you the real cost per active gram, and it lets you compare this product against lower assay powders honestly.
What daily dose should I start with?
Start with 0.5 g of powder, which gives 100 mg PS, and observe how you feel after three days. If needed, increase to 1 g (200 mg PS) once daily. Avoid going beyond 300 mg PS per day without professional supervision.
Is this powder suitable for vegans?
Yes, the powder itself is vegan because it comes from sunflower lecithin and contains no gelatin or animal derivatives. If you put the powder into capsules, confirm that the capsule shells also use plant-based material.
Does hot water destroy phosphatidylserine?
Prolonged heat can degrade phospholipids. Keep the powder in beverages below 65°C, and do not boil it. Mixing into a warm drink for a few seconds is fine, but for long-term stability, cold or room-temperature mixing is safer.
What does 20% phosphatidylserine mean exactly?
It means every 100 mg of dry powder contains 20 mg of pure L-α-phosphatidylserine, measured by HPLC. The remaining material is mostly other natural phospholipids from the sunflower lecithin, such as phosphatidylcholine, which supports emulsification in water.
Differentiation Summary
Unlike generic PS supplements that emphasize capsule count or total powder weight, Lixing Phosphatidylserine states active PS content per serving, uses a 20% HPLC assay, and provides batch-specific COA data. Its sunflower base separates it from soy-based powders and avoids common taste, allergy, and bovine-derived concerns. This makes it a straightforward choice for buyers who judge value by cost per active milligram rather than bulk powder price.
