Common Questions

What is the recommended dosage?
Take one capsule daily with a meal containing some fat to improve absorption. In high-demand periods, you may increase to two capsules daily but do not exceed three capsules.
How long before seeing improvement?
Most users report noticeable changes in focus and recall after four to six weeks of continuous use, while clinical studies have measured effects within 6–12 weeks.
Can I take this alongside omega-3 or vitamin B12?
Yes, phosphatidylserine pairs well with omega-3 fatty acids, B vitamins, and magnesium. If you are on anticoagulant medication, speak with your doctor first.
Is this product really soy-free?
Yes. The entire phosphatidylserine is extracted from sunflower lecithin, so there are no soy proteins or soy derivatives in the product.
Is long-term use safe?
Published trials have used doses of 200–300 mg daily for up to 12 months without serious adverse events. Use the minimum effective dose and take breaks if needed.
Does the product contain animal-derived ingredients?
No. The capsule shell is vegetable-based HPMC, and neither the active ingredient nor the excipients come from animal sources.
What if I have a sunflower seed allergy?
Do not use this product if you have a sunflower seed allergy, because the lecithin is derived from sunflower seeds.
How should I store it to keep its potency?
Store it below 25°C (77°F) in a dry, dark place. Avoid storing in the bathroom where humidity and heat can degrade the capsules.

Differentiation Summary

Compared with conventional soy-derived phosphatidylserine on the market, this product eliminates soy allergen risk and delivers a verified purity of ≥98% via HPLC analysis. The delayed-release capsule design also reduces stomach irritation common with standard immediate-release supplements. Clean-label features, including no magnesium stearate and transparent batch contaminant reports, make it a suitable choice for health-conscious adults over 45, vegetarians, and individuals who need consistent cognitive support but have prior experience with poor-tolerated nootropics.
