Brief summary

The goal of this clinical trial is to test in Japanese adults who feel sleepy when they wake up. The question it aims to answer are: •Does taking plasmalogens reduce sleepiness upon waking? Participants will be given the following tasks: * Take 4 capsules daily containing plasmalogens for 12 weeks. * Answer the questionnaire on sleepiness1 when they wake up. * Answer the questionnaire on daytime sleepiness2. Researchers will compare plasmalogens and placebo groups to see if plasmalogens reduce sleepiness upon waking.

Interventions

DIETARY_SUPPLEMENTFood containing plasmalogen

Take four capsules per day in the morning.

DIETARY_SUPPLEMENTFood without plasmalogen

Design outcomes

Primary

MeasureTime frameDescription
The measured value of Zc score of sleepiness on rising in the OSA sleep inventory MA version (OSA-MA) after the 12-week interventionAfter the 12-week interventionThe OSA-MA is used to assess sleep quality. Individuals are asked to complete the questionnaire immediately after waking on the examination day and two days before the examination. The raw scores from each examination day will be converted to Zc scores, and the three-day mean, rounded to one decimal place, will be used as the measured value. Sleepiness on rising consists of four questions. Higher score indicates better outcome.

Secondary

MeasureTime frameDescription
The measured value of Zc score of sleepiness on rising in the OSA-MA after the 6-week interventionAfter the 6-week interventionThe OSA-MA is used to assess sleep quality. Individuals are asked to complete the questionnaire immediately after waking on the examination day and two days before the examination. The raw scores from each examination day will be converted to Zc scores, and the three-day mean, rounded to one decimal place, will be used as the measured value. Sleepiness on rising consists of four questions. Higher score indicates better outcome.
The measured values of Zc score of initiation and maintenance of sleep, frequent dreaming, refreshing, and sleep length in the OSA-MA after the 6 and12-week interventionAfter the 6 and12-week interventionThe OSA-MA is used to assess sleep quality. Individuals are asked to complete the questionnaire immediately after waking on the examination day and two days before the examination. The raw scores from each examination day will be converted to Zc scores, and the three-day mean, rounded to one decimal place, will be used as the measured value. Initiation and maintenance of sleep consists of five questions, frequent dreaming consists of two questions, refreshing consists of three questions, and sleep length consists of two questions. Higher scores indicate better outcomes.
The measured value of total score of the Athens Insomnia Scale (AIS) after the 6 and12-week interventionAfter the 6 and12-week interventionThe AIS is used to assess sleep-related issues over the past month. Individuals are asked to answer eight sleep-related questions by selecting one of four response options, indicating experiences they have had at least three times per week in the past month. Lower score indicates better outcome.
