Not Applicable

Completed

• Conditions: Healthy
• Interventions: Other: Placebo; Dietary Supplement: Investigational

• Registration Number: NCT05548595
• Lead Sponsor: Hong Kong Prospect Group Co. Limited

Brief Summary

Nutritional products such as spearmint extract, alpha-glyceryl phosphoryl choline and phosphatidylserine may have anti-oxidative and anti-inflammatory effect that may be effective in improving cognition. This study aims to evaluate the impact of a nutritional product on cognition in healthy teenagers.

Detailed Description

There is a growing interest in the nootropic properties of nutritional supplements, especially for improving cognitive processes such as attention, perception, evaluation, and working memory. Spearmint extract, alpha-glyceryl phosphoryl choline, and pyrroloquinoline quinone have antioxidative properties that may contribute to cognitive function, and spearmint extract has demonstrated attention-enhancing effects in young adults and memory-improving effects in elderly population. Phosphatidylserine is a phospholipid found abundantly in the brain that has also been evidenced to be effective in improving cognition.

This randomized, double-blind study will be conducted to determine whether a nutritional supplement containing spearmint extract, phosphatidylserine, alpha-glyceryl phosphoryl choline, and pyrroloquinoline quinone ("Brain Doctors Formula Mega Brain Boost") is safe and effective in improving cognitive function in healthy participants aged 12 to 18 years.

Primary Outcome Measures

Name	Time	Method
To determine the impact of test product on the executive cognitive function in healthy adolescents within the group and when compared to the placebo	after 3 and 6 weeks	Change from baseline in national institute of health (NIH) Toolbox Dimension Change Card Test (aged 12+ version) after 3 and 6 weeks. Dimensional Change Card Sort Test is a measure of cognitive flexibility. The scoring range is provided as an age-corrected normative score. A score of 100 indicates performance that is at the national average for the participant's age. A score of 115 or 85 would indicate that the participant's performance is 1 SD above or below the national average, respectively, when compared with like-aged participants
To determine the impact of test product on the attention and executive cognitive function in healthy adolescents within the group and when compared to the placebo	after 3 and 6 weeks	Change from baseline in NIH Toolbox Flanker Inhibitory Control and Attention Test (12+) after 3 and 6 weeks. The Flanker task measures both attention and inhibitory control. A score of 100 indicates performance that is at the national average for the participant's age. A score of 115 or 85 would indicate that the participant's performance is 1 SD above or below the national average, respectively, when compared with like-aged participants
To determine the impact of test product on the cognitive processing speed of healthy adolescents within the group and when compared to the placebo	after 3 and 6 weeks	Change from baseline in NIH Toolbox Pattern Comparison Speed Test after 3 and 6 weeks. This test measures speed of cognitive processing. A score of 100 indicates performance that is at the national average for the participant's age. A score of 115 or 85 would indicate that the participant's performance is 1 SD above or below the national average, respectively, when compared with like-aged participants
To determine the impact of test product on the working memory of healthy adolescents within the group and when compared to the placebo	after 3 and 6 weeks	Change from baseline in the Symmetry Span Task after 3 and 6 weeks. The symmetry span task is a measure of working memory capacity. Scores on the task range from 0-42 with higher scores representing greater working memory capacity
To determine the impact of test product on self reported mind wandering of healthy adolescents within the group and when compared to the placebo	after 3 and 6 weeks	Change from Week 1 in the self assessment of mind wandering, as captured in a study daily diary, after 3 and 6 weeks by using the The Mind Wandering Questionnaire. The Mind Wandering Questionnaire is a retrospective measure of mind wandering in a everyday life. A scoring range is between 1-6. Higher scores on this scale represent greater levels of mind wandering experienced
To assess the safety and tolerability of the test product in healthy adolescents	6 weeks	Assessing the severity of adverse events (mild, moderate, severe) over the study period
