Frequently Asked Questions

Is soy or sunflower phosphatidylserine better?

Both forms have identical molecular structures and comparable bioactivity. Soy-derived PS has more clinical trial data behind it, but sunflower-derived PS avoids soy allergen concerns and is non-GMO. Either source is effective at standard doses of 100-300mg daily.

How long does phosphatidylserine take to work?

Most clinical trials show measurable cognitive improvements after 6-12 weeks of consistent daily use. Some users report subtle improvements in focus within 2-4 weeks. For cortisol reduction, effects may be noticed sooner, within 2-3 weeks.

Can phosphatidylserine help with ADHD?

Emerging research suggests PS may benefit children and adults with ADHD. A 2012 study by Hirayama et al. found that PS supplementation improved attention and impulsivity in children with ADHD. However, the evidence is still emerging and PS should not replace standard ADHD treatments without medical guidance.
