Frequently Asked Questions
What is the recommended dosage for Lixing phosphatidylserine?
The standard serving is one 100 mg capsule per day with a meal. Some clinical studies use 200–300 mg total per day in divided doses, but you should consult a healthcare professional before exceeding the labeled amount.
How long does it take to see improvements in memory?
Most clinical trials assess cognitive changes after 6 to 12 weeks of daily supplementation. Some individuals report earlier improvements in focus, but consistent intake over several weeks is generally needed for measurable benefits.
Is this product safe for long-term use?
Phosphatidylserine has been used in human studies for up to 16 weeks with no serious adverse effects reported. For continuous use beyond that, ask your doctor or pharmacist, especially if you take blood-thinning or antidepressant medications.
Does Lixing phosphatidylserine contain soy?
No, this product is derived entirely from non-GMO sunflower lecithin. It is appropriate for people with soy allergies or sensitivities, as no soy-based ingredients are used in manufacturing.
Can I take it together with other brain supplements?
Yes, phosphatidylserine is often combined with omega-3 fish oil, vitamin B12, or creatine. Start with one new supplement at a time, and monitor how you feel over two weeks before adding another.
What does “high purity” actually mean in this product?
High purity means at least 98% of the extracted powder is pure phosphatidylserine, as quantified by HPLC analysis. This leaves less than 2% other lipids or residues, unlike typical 20% PS blends found in many commercial products.
Is this product suitable for vegans?
Yes, the capsule shell is made from hypromellose, a plant-derived cellulose. All other ingredients are also free from animal sources, so the entire product is fully vegan-friendly.
How should I store the product to keep it fresh?
Store the bottle in a cool, dry place below 25°C (77°F), away from direct sunlight and moisture. Always close the cap tightly after each use, and do not refrigerate unless stated on the label.
Why This PS Stands Out
Most commercial phosphatidylserine supplements use soy-derived lecithin with purity levels around 20–50%, which means a large portion of the dose is unrelated fat. Lixing’s version is different: it uses sunflower lecithin as the raw material and purifies the PS to 98%, verified by HPLC with a certificate of analysis for every batch. This approach minimizes allergen exposure, avoids genetically modified soy sources, and removes the need for artificial solvents during processing. Combined with a vegetarian capsule and minimal excipients, this product is best suited for individuals who want a clean, traceable, and effective cognitive supplement without relying on animal-derived ingredients or vague concentration claims.
