About this study

Official title: The Effects of Natural Bioactive Compounds on Sleep and Stress: A Randomized Double-Blind Placebo-Controlled 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:

Read more
  • 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.

Read the detailed description

The Effects of Natural Bioactive Compounds on Sleep and Stress: A Randomized Double-Blind Placebo-Controlled Trial This four-arm, parallel-group trial evaluates bioactive compounds targeting stress-sleep pathophysiology (lavender oil, PEA, and OEA). The 8-week intervention employs validated psychometric instruments alongside salivary biomarkers providing objective HPA axis and circadian rhythm assessment. The trial enrolls 240 participants (60 per arm) with moderate stress (PSS ≥14) and sleep complaints.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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.

    Measured: Day 1 to day 57

  2. 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.

    Measured: Day 1 to day 57

  3. 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.

    Measured: Day 1 to day 57

Secondary outcomes (15)
  1. 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.

    Measured: Day 1 to day 57

  2. 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.

    Measured: Day 1 to day 57

  3. 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.

    Measured: Day 1 to day 57

  4. 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.

    Measured: Day 1 to day 57

  5. Sleep efficiency

    Change from baseline to the end of the study period in Sleep efficiency as measured by ratio of total sleep time to time in bed (PSQI). 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.

    Measured: Day 1 to day 57

  6. Daytime sleepiness

    Change from baseline to the end of the study period in Daytime sleepiness via Functional Outcomes of Sleep Questionnaire (FOSQ-10). The FOSQ-10 consists of 10 items distributed among 5 subscales i.e. general productivity (2 item), activity level (3 items), vigilance (3 items), social outcomes (1 item) and sexual relationship (1 item). Items are rated on a scale of 1-4 (1 = extreme difficulty, 2 = moderate difficulty, 3 = a little difficulty, 4 = no difficulty). The total score is the sum of the 5 sub scores.

    Measured: Day 1 to day 57

  7. Eating in response to experienced stress

    Change from baseline to the end of the study period in Eating in response to experienced stress via the Salzburg Stress Eating Scale (SSES). The SSES is a questionnaire use to measure eating in response to experienced stress. The response categories range from 'I eat much less than usual' to 'I eat much more than usual' and are scored on a 5-point Likert scale, i.e., a score from 1 - 5. Higher scores indicate that the respondent eats more when stressed is experienced.

    Measured: Day 1 to day 57

  8. Serotonin

    Change from baseline to the end of the study period in serotonin via saliva test.

    Measured: Day 1 to day 57

  9. Cortisol

    Change from baseline to the end of the study period in cortisol via saliva test.

    Measured: Day 1 to day 57

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 23 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Australia. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Amanda Rao, PhD (+61 (0) 7 3102 4486, research@rdcglobal.com.au), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Perceived stress via Perceived Stress Scale (PSS) (time frame: Day 1 to day 57). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Apr 2026.
