Supplementation with 100 mg of sunflower-derived phosphatidylserine daily for 12 weeks showed no differences in primary or secondary cognitive outcomes in healthy neurotypical children aged 8-12 years, though a pre-defined subgroup of children with consistently below-median baseline cognitive performance showed benefit on a visuospatial memory task.
Key Findings
Results
Phosphatidylserine supplementation showed no statistically significant differences in primary or secondary cognitive outcomes in the total cohort of healthy children.
Participants were healthy, neurotypical children aged 8–12 years
Intervention consisted of 100 mg of sunflower-derived PS (Sharp PS green) daily in gummy form for 12 weeks
Assessment battery was completed at baseline, 6 weeks, and 12 weeks
Outcomes monitored included cognitive performance, mood, and sleep
Results
In a pre-defined subgroup of children with consistently below-median baseline cognitive performance, PS supplementation showed a benefit on a visuospatial memory task.
The subgroup was selected based on 'constant below median performance across the cognitive tasks at baseline'
This was a pre-defined subgroup analysis
The specific benefit was observed on a visuospatial memory task
No benefits were observed on other cognitive tasks within this subgroup based on the abstract
Results
Supplementation with 100 mg of sunflower-derived PS daily for 12 weeks was found to be safe and well tolerated in healthy children aged 8–12 years.
The product used was Sharp PS green, a sunflower-derived phosphatidylserine
Dose was 100 mg per day administered in gummy form
Duration of supplementation was 12 weeks
Safety and tolerability were assessed as part of the trial outcomes
Methods
The study was a randomized, placebo-controlled clinical trial comparing sunflower-derived PS to a matching placebo in healthy, neurotypical children.
Trial was retrospectively registered at ClinicalTrials.gov (NCT05177978)
Participants were aged 8–12 years
Placebo was described as 'a matching placebo' in gummy form
The trial included assessments at baseline, 6 weeks, and 12 weeks
Background
Prior literature indicates that phosphatidylserine supplementation is associated with cognitive and neuropsychological benefits in adults and has been shown to mitigate symptoms of inattention in children with ADHD, but there is little data on PS effects in healthy children.
PS benefits have been reported in both healthy and neuro-compromised adults
PS has been shown to mitigate symptoms of inattention specifically in children with attention-deficit hyperactivity disorder
The authors identified a gap in the literature regarding PS effects in healthy, neurotypical children
This gap motivated the design of the current randomized controlled trial
