A Exploratory Study of NatureU Sweet Dream on Sleep Outcomes (NUSD)

May 13, 2026 updated by: OmniSolutions Laboratory Holdings Limited

A Single-Center, Open-Label, Exploratory Self-Controlled Study of NatureU Sweet Dream on Deep Sleep Duration and Deep Sleep Percentage in Adults With Sleep Disturbance

This was a single-center, open-label, exploratory self-controlled study evaluating NatureU Sweet Dream on sleep outcomes in adults with mild to moderate sleep disturbance. Seventeen participants were enrolled, 2 participants were lost to follow-up, and 15 participants provided valid effectiveness data. Participants completed two independent test-food sessions using wearable sleep monitoring. The comparator session used a commercially available melatonin product, and the test-product session used NatureU Sweet Dream. The main outcomes were deep sleep duration and deep sleep percentage measured by a wearable device and exported through the Huawei Health application. No adverse reactions were reported during the study.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The study evaluated the effect of NatureU Sweet Dream, an oral functional food product containing GABA and Lactium, on sleep outcomes. During the screening period, study staff explained the study procedures, product intake method, and wearable monitoring method, and participants signed informed consent before enrollment. Participants were issued a Huawei Band 8 wearable device and the study product. Participants maintained normal diet and routines, avoided alcohol, and used the wearable device for sleep monitoring. In each independent test-food session, participants avoided excessive exercise 2 hours before sleep, took the assigned product with warm water 1 hour before sleep, turned off light sources before sleep, and exported sleep monitoring data the next morning from the Huawei Health application. Study enrollment started on April 15, 2024. Primary completion and last follow-up occurred on April 17, 2024. This exploratory study had no blinding and was intended to generate preliminary within-participant evidence for sleep-related outcomes.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult

Accepts Healthy Volunteers

No

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Difference in Deep Sleep Duration Between NatureU Sweet Dream and Comparator Product
Time Frame: 24 hours
Deep sleep duration in minutes was measured using the Huawei Band 8 wearable device and exported from the Huawei Health application after each test-food session. The primary endpoint was the difference in deep sleep duration after NatureU Sweet Dream compared with the commercially available melatonin product.
24 hours

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Difference in Deep Sleep Percentage Between NatureU Sweet Dream and Comparator Product
Time Frame: 24 hours
Deep sleep percentage was measured using the Huawei Band 8 wearable device and exported from the Huawei Health application after each test-food session. The secondary endpoint was the difference in deep sleep percentage after NatureU Sweet Dream compared with the commercially available melatonin product.

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
