Acute cognitive effects of standardised Ginkgo biloba extract complexed with phosphatidylserine
Kennedy DO
Published in Human Psychopharmacology
Methodology
Randomized, double-blind, placebo-controlled balanced crossover study in healthy young adults; cognitive performance measured with the Cognitive Drug Research battery at several time points after single doses.
Key Findings
A single dose of Ginkgo biloba extract complexed with phosphatidylserine improved secondary memory and speed of memory performance and modestly improved mood ratings compared with placebo and with standard ginkgo extract.
Conclusions
Ginkgo complexed with phosphatidylserine improved secondary memory and speed of memory performance.
Limitations
Small sample (n=28), acute single-dose design in healthy young adults, and multiple cognitive outcomes raising the chance of false-positive findings.
Supplements Studied
Administration of GBE complexed with phosphatidylserine resulted both in improved secondary memory performance and significantly increased speed of memory task performance.
