Frequently Asked Questions
How much phosphatidylserine should I take per day?
There is no FDA daily allowance, but published human trials use between 100 and 300 mg daily. For this supplement, 100 mg twice a day is the recommended dose. Beginners can take one capsule each morning for the first week to check tolerance before going up to two.
How long does it take to notice a difference?
In an eight-week intervention study on older adults with self-reported memory complaints, 300 mg/day of phosphatidylserine improved word recall compared to placebo. The results of that trial are available on PubMed. At 200 mg/day, you should allow at least four weeks before evaluating changes.
Can I take it with coffee or other supplements?
Yes. Phosphatidylserine has no known negative interaction with caffeine. Combining it with your morning coffee should not reduce absorption. If you take a multivitamin, you can swallow both together, as it does not compete with minerals for uptake.
What's the difference between sunflower-derived and soy-derived phosphatidylserine?
Soy-derived phosphatidylserine is cheaper and more common, but it can be a problem for people with soy allergies. Sunflower-derived phosphatidylserine has an identical molecular structure and is extracted without hexane or chemical solvents, making it a hypoallergenic alternative.
Is it safe for long-term use?
Human studies indexed in PubMed have used doses of 300 to 400 mg daily for up to six months without serious side effects. The 200 mg daily intake suggested for this product is below that level. If you take blood thinners or have a medical condition, speak with a doctor before adding any supplement.
Does phosphatidylserine cause drowsiness?
Some users report slightly deeper sleep when taking phosphatidylserine later in the day, but daytime drowsiness is not typically reported. If you think it makes you tired, move the second capsule from lunchtime to dinner rather than taking two in the morning.
Does Lixing Phosphatidylserine contain soy or gluten?
No. The active ingredient comes from sunflower lecithin, and the remaining capsule ingredients contain no soy, gluten, dairy, or eggs. The finished product is tested for allergens; the facility is not gluten-free certified, but the formula is free of gluten sources.
How It Compares with Other Phosphatidylserine Supplements
Most phosphatidylserine pills use soy-derived lecithin, and many include gel capsules containing animal gelatin and microcrystalline cellulose fillers. This product stands apart because it uses sunflower-derived phosphatidylserine, a hexane-free extraction route, and a plant-based capsule. The per-capsule 100 mg dose and third-party batch testing also mean you can verify exactly what you are taking. That appeals to vegans, people with soy sensitivities, and anyone who wants a clean-label no-filler cognitive supplement.
