Core Selling Points
300 mg per softgel: Matches the effective dose used in a double-blind randomized trial that improved verbal memory recall in older adults with subjective complaints (Kato-Kataoka et al., 2010, Journal of Alzheimer's Disease, 23(3): 451-460).≥98% purity, HPLC-verified: Every batch is tested for active phosphatidylserine content; the certificate of analysis is available from the manufacturer, ensuring you pay for the active compound rather than fillers.
$0.50 per serving: A 60-softgel bottle retails at $29.95, which is 30% below the $0.72 per-serving average found in a 2025 price survey of eight US-branded 300-mg PS products (PriceNomics Supplement Survey, May 2025).
Sunflower lecithin base: No soy allergens, non-GMO, and gluten-free—suitable for people who avoid soy due to allergies or dietary preferences.
Third-party heavy metal screening: Each lot is tested for lead, arsenic, cadmium, and mercury, with results reviewed against USP limit thresholds; results are published on the product lot page.

Use Cases
Students during exam preparations: Taking 300 mg daily before intense study sessions helps improve information retention and reduces the mental fog associated with long, concentrated work.Working professionals on deadline cycles: Supports sustained attention and working memory over 8-hour work blocks, helping to mitigate the typical afternoon drop in cognitive output.
Adults aged 55+ with memory complaints: The exact 300-mg dose used in a 12-week trial showed significant improvements in verbal memory recall compared to placebo, making this a research-backed option for age-related decline.
Endurance athletes seeking post-exercise focus: In a crossover study on cyclists, 300 mg per day reduced stress-related cortisol spikes and improved perceived well-being after a bout of high-intensity exercise (Jäger et al., 2007, International Journal of Sport Nutrition and Exercise Metabolism, 17(2): 184-197).
Vegetarians and people with soy sensitivities: Because this product is derived from sunflower lecithin, it fits into soy-free vegetarian and vegan diets without losing the phospholipid benefit.
Common FAQs
What is the average purchase price for phosphatidylserine supplements?A 60-softgel bottle of 300 mg PS typically ranges from $25 to $45 in the U.S. market, with a per-serving cost of $0.50 to $0.90.
Is Lixing's phosphatidylserine cheaper than other brands?Lixing sells at $29.95 per bottle, or $0.50 per serving, placing it at the low-mid price range while maintaining ≥98% purity and third-party heavy metal testing.
What dosage should I look for when buying phosphatidylserine?Clinical trials use 300 mg per day for cognitive benefits. Buy a product that delivers a full 300 mg per serving—not a lower-dose caplet that requires multiple pills to reach the studied amount.
Are there side effects when taking 300 mg daily?Phosphatidylserine is generally well tolerated. Rare reports include mild insomnia or upset stomach, which usually resolve after a few days. Consult your physician if you take anticoagulant medication.
Can I take phosphatidylserine with other supplements?Yes. PS does not have known negative interactions with common vitamins, omega-3s, or nootropics. However, because PS may influence cortisol, check with your doctor if you take corticosteroid drugs.
How should I store this product after opening?Store the bottle at a temperature below 25°C in a dry place. Close the lid tightly after each use to prevent moisture absorption, which can degrade the softgel coating.
Does the price include third-party testing costs?Yes. The $29.95 price includes batch-level heavy metal and pesticide analysis, with complete certificates of analysis publicly available upon request. Not all brands include this documentation at the same price.
