    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.
