About this trial
The goal of this clinical trial is to learn if natural supplements (lavender oil, PEA, and OEA) work to improve sleep and reduce stress in adults with moderate stress levels and sleep difficulties. It will also learn about the safety of these natural supplements.
The main questions it aims to answer are:
* Do these supplements improve sleep quality? * Do they reduce perceived stress levels? * Do they reduce anxiety symptoms? * What medical problems do participants have when taking these supplements?
Researchers will compare three active treatment groups (lavender oil, PEA, Trpti which contains OEA) to a placebo (a look-alike capsule that contains no active ingredients) to see if these natural supplements work to improve sleep and reduce stress.
Participants will take 1 capsule (either active supplement or placebo) every day for 8 weeks and attend 2 clinic visits with a phone check in in between.

Treatment groups
Trial outcomes
Primary outcomes
Perceived stress via Perceived Stress Scale (PSS)
Change from baseline to the end of the study period in Perceived stress via Perceived Stress Scale (PSS). The Perceived Stress Scale is a self-reported tool for measuring psychological stress. A total PSS-10 score from 0 to 40 is presented, with higher scores representing higher levels of stress.
Anxiety via Beck Anxiety Inventory (BAI)
Change from baseline to the end of the study period in Anxiety via Beck Anxiety Inventory (BAI). The BAI is a 21-item self-report questionnaire evaluating anxiety symptoms, rated on a 4-point scale.
Sleep quality
Change from baseline to the end of the study period in Sleep quality. This will be measured via Pittsburgh Sleep Quality Index (PSQI) and Consensus Sleep Diary. The PSQI is a self-report questionnaire used to evaluate overall sleep quality. Each of the 19 items belongs to one of seven subcategories: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleeping medication, and daytime dysfunction. The Consensus Sleep Diary is designed to gather information about daily sleep patterns.
Secondary outcomes
Mental wellbeing
Change from baseline to the end of the study period in Mental wellbeing via The World Health Organization-Five Well-Being Index (WHO-5). The WHO-5 is a self-report instrument measuring mental well-being. It consists of five statements relating to the past two weeks. Each statement is rated on a 6-point scale, with higher scores indicating better mental well-being. A score ≤ 50 (or \< 13 in the raw score) is associated with poor well-being or psychological distress and a score ≤ 28 may denote possible clinical symptoms of depression.
Mood
Change from baseline to the end of the study period in Mood via Profile of mood states (POMS). The POMS is a self-reported questionnaire consisting of 65 items, designed to evaluate individuals within seven different mood domains: fatigue-inertia, anger-hostility, vigor-activity, confusion-bewilderment, depression-dejection, tension-anxiety, and friendliness.
Sleep duration
Change from baseline to the end of the study period in Sleep duration via PSQI and Consensus Sleep Diary. The PSQI is a self-report questionnaire used to evaluate overall sleep quality. Each of the 19 items belongs to one of seven subcategories: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleeping medication, and daytime dysfunction. The Consensus Sleep Diary is designed to gather information about daily sleep patterns.
Sleep onset latency
Change from baseline to the end of the study period in Sleep onset latency as measured by duration of time (minutes) from turning light off to falling asleep (PSQI and Consensus Sleep Diary). The PSQI is a self-report questionnaire used to evaluate overall sleep quality. Each of the 19 items belongs to one of seven subcategories: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleeping medication, and daytime dysfunction. The Consensus Sleep Diary is designed to gather information about daily sleep patterns.
