Phosphatidylserine Interactions

Phosphatidylserine bound to omega-3 fatty acids (particularly DHA) is more readily incorporated into neuronal membranes than either nutrient alone, supporting membrane fluidity, neurotransmitter release, and memory consolidation. Clinical trials of PS-DHA preparations show improvements in memory and sustained attention in older adults with subjective memory complaints.

Ginkgo biloba improves cerebral blood flow and has antioxidant effects; complexing it with phosphatidylserine substantially enhances absorption of its active terpene lactones and flavone glycosides. The Virtiva complex (ginkgo + phosphatidylserine) showed improved secondary memory and faster memory task performance versus ginkgo alone in a placebo-controlled crossover trial.
