Impact of Levagen+® Palmitoylethanolamide (PEA) in a Cross-Over Trial Examining Stress and Cognition in University Students (IMPRESS)
The Effect of Levagen+® Palmitoylethanolamide (PEA) Supplementation on Parameters of Stress, Wellbeing and Cognition in University Students
The goal of this randomised cross-over trial is to learn about the effects of Levagen+® Palmitoylethanolamide (PEA) supplementation on cognition, wellness and well-being in young and healthy university students.
The main question it aims to answer is:
• Does the PEA supplementation affect parameters of stress, mood, cognition and well-being in university students?
Participants will complete 2 baseline on-site visits during which they will be assigned to Levagen+® Palmitoylethanolamide (PEA) treatment or placebo arm each time and:
- complete anthropometric measurements, questionnaires and surveys,
- undergo blood and saliva sampling
- complete a cognitive assessment (CANTAB)
- a randomly chosen cohort will also measure heart rate variability (HRV) over 3 days.
Researchers will compare the PEA treatment group to the placebo to see if there is a significant difference.

Detailed Description
The study will investigate the effect of Levagen+® Palmitoylethanolamide (PEA) supplementation on parameters of stress, well-being and cognition at defined time points. Assessments will be made using a combination of a range of stress measures, which will include physiological and psychometric parameters.
Physiological measures will include assessments of known biomarkers of the principal stress-sensitive physiological systems, the hypothalamic-pituitary-adrenal axis, and the autonomic nervous system, while psychometric measures will include established instruments to assess general health, somatic stress symptoms, academic stress, response to stress, cognition, and mood.

Measure Description |
Time Frame |
---|---|---|
To assess the influence of PEA supplementation on HRV in female population.
Time Frame: The parameters were measured for 3 continuous days following the baseline visit (day 1, day 2 and day 3) and for 3 continuous days following the endpoint visit (day 42, day 43 and day 44) of the study period.
|

|
The Perceived Stress Scale (PSS) a 10-item questionnaire was used to measure the degree to which situations in the participant's life were appraised as stressful. The questions investigate how often certain feelings and thoughts were experienced on a five-point scale from 'never' to 'very often' (never =0, almost never = 1, sometimes = 2, fairly often = 3 and very often = 4) during the 3-day observation periods. To calculate a total PSS score, responses to the four positively stated items (items 4, 5, 7 and 8) first need to be reversed (i.e. 0 => 4; 1 => 3; 2 => 2; 3 => 1; 4 => 0). The PSS score were then obtained by summing across all items. Higher scores indicate higher levels of perceived stress. |
The parameters were measured for 3 continuous days following the baseline visit (day 1, day 2 and day 3) and for 3 continuous days following the endpoint visit (day 42, day 43 and day 44) of the study period.
|

|
The parameters were measured for 3 continuous days following the baseline visit (day 1, day 2 and day 3) and for 3 continuous days following the endpoint visit (day 42, day 43 and day 44) of the study period.
|
To study the influence of PEA supplementation on well-being in females.
Time Frame: The parameters were measured for 3 continuous days following the baseline visit (day 1, day 2 and day 3) and for 3 continuous days following the endpoint visit (day 42, day 43 and day 44) of the study period.
|
Student Well-being Process Questionnaire (WPQ) a 44-item questionnaire was used to examine predictors of positive well-being, adverse mental health, and cognitive function.
The responses to questions 1 - 42 were assessed on a 10-point scale and or questions 43 and 44 on a 4-point scale.
Where with outcomes related to positive well-being high scores = more positive; with outcomes related to adverse mental health high scores = more negative and with outcomes related to cognitive function high scores = more cognitive problems.
Positive well-being was predicted by high positive personality, high social support and low stressor and low negative coping scores.
Negative outcomes were predicted by high stressor, coping and conscientiousness scores, and low positive personality and low social support scores.
Cognitive problems were predicted by high stressor and negative coping scores and low positive personality scores.
|
The parameters were measured for 3 continuous days following the baseline visit (day 1, day 2 and day 3) and for 3 continuous days following the endpoint visit (day 42, day 43 and day 44) of the study period.
|

|
Salivary Cortisol levels were measured during morning, afternoon and evening for 3 days following each baseline and endpoint visit at home.
|
The parameters were measured in morning and afternoon samples collected over 3 continuous days following the baseline visit (day 1, day 2 and day 3) and 3 continuous days following the endpoint visit (day 42, day 43 and day 44) of the study period.
