Ginkgo and Phosphatidylserine Combo Shows Stress and Memory Signals in Exploratory Trials
By Nutranexa News |
Two exploratory randomized trials of a standardized Ginkgo biloba extract combined with phosphatidylserine reported memory and reaction-time signals and mood improvements.
Trial Design
Researchers conducted two exploratory, registered randomized controlled trials of a standardized Ginkgo biloba extract associated with phosphatidylserine, published in Food Science & Nutrition in June 2026.
The first trial tested a 480 mg/day dose, while the second enrolled adults experiencing moderate stress who received either 240 mg/day or 480 mg/day of the combination for four weeks.
Main Findings
In the first trial, participants showed improvements in delayed verbal memory and reaction time versus placebo, suggesting a possible benefit on cognitive performance.
In the second trial, both doses were associated with improvements in mood states and a visually consistent downward trend in reaction times across four cognitive performance tests.
The authors describe the trials as exploratory, meaning larger confirmatory studies are still needed.
Buyer Takeaway
For formulators, the results illustrate continued commercial interest in combining botanical extracts with phosphatidylserine in stress and cognitive support products.
Buyers should treat the findings as preliminary and evaluate supplier dossiers against the need for larger trials and market-specific claim rules.
