NCT05177978

Brief Summary

The purpose of this study is to assess the cognitive effects (attention, learning, and memory) of 6 and 12 weeks administration of a supplement containing phosphatidylserine in comparison to a placebo in healthy children aged 8 to 12 years old. The study will utilize Rey Auditory Verbal Learning Test (RAVLT) and Computerised Mental Performance Assessment System (COMPASS, Northumbria University) for a broad assessment of cognitive function/learning, and actigraphy to monitor sleep.

You may not qualify if:

  • Relevant allergy or known hypersensitivity to one of the ingredients contained in the investigational drug.
  • Are currently taking any illicit, herbal or recreational drugs including alcohol and tobacco.
  • Taking any prescribed or OTC medication against chronic or non- chronic illnesses.
  • Have used dietary supplements within the last 4 weeks
  • Are diagnosed with ADHD, dyslexia or any neurodevelopmental disorder or learning difficulty.
  • Suffer from visual (including colour blindness) or hearing impairment (that may impact task performance in the opinion of the PI.
  • Have any serious illness, cognitive impairment or medical disorder that may confound with study results or interfere with compliance.
  • Have any other active or unstable medical condition, that, in the opinion of the PI, may adversely affect the participant's ability to complete the study
  • Are experiencing exceptional social/family stressors.
  • Consume more than one portion (\>100g) per week of the following dietary sources high in phosphatidylserine: Oily fish such as salmon, mackerel, herring, tuna and eel. Animal internal organs such as liver, kidney, brain and heart. Note: Information on continued adherence to this criteria will be captured within treatment diary. If a child continuously consumes more than one portion per week of PS rich food the sponsor will be informed on a case by case basis. If deemed to be significant, they will be excluded, (but allowed to continue the study to the end (day 84)) and will be replaced.
  • Subjects that have followed specific diet, e.g. high protein diet, within 30 days prior to study start
  • Serious diet change, e.g. Ketogenic or vegan, within 30 days prior to study start.
  • Consumption of \> 250 mg/day of caffeine.
