Evidence-Based Benefits

  • Memory and cognitive function — a 2010 double-blind RCT (Kato-Kataoka et al.) found 100mg/day PS significantly improved memory scores in elderly subjects with mild cognitive complaints over 6 months
  • Attention and processing speed — Baumeister et al. (2008) demonstrated that 400mg/day PS improved cognitive performance during stressful arithmetic tasks in young adults
  • Cortisol modulation — PS supplementation at 600mg/day blunted cortisol response to exercise-induced stress by up to 30% in a controlled trial (Monteleone et al., 1992)
  • Age-related decline prevention — the FDA permits a qualified health claim stating PS may reduce the risk of cognitive dysfunction in the elderly (2003 qualified health claim)
  • Neurotransmitter support — PS facilitates acetylcholine and dopamine release by maintaining optimal cell membrane fluidity in presynaptic neurons

What the Research Says

Phosphatidylserine has a solid evidence base for cognitive support in aging populations. The FDA issued a qualified health claim in 2003 acknowledging that PS may reduce the risk of cognitive dysfunction in the elderly. Kato-Kataoka et al. (2010) demonstrated memory improvements in a 6-month RCT. Earlier bovine-derived PS studies (Crook et al., 1991) showed significant cognitive benefits, and soy-derived PS has been confirmed to have comparable efficacy. Monteleone et al. (1992) established the cortisol-blunting effect that makes PS valuable for stress management.
