Objectives

Narrative objectives1

In order to clarify the effects of Labret's Bacillus subtilis intake on sleep in healthy Japanese adult males and females aged 18 to 80 years who have some problems or troubles with sleep, objective evaluation of sleep by measuring EEG and other bioelectrical potentials from bedtime to waking and subjective evaluation of sleep using a sleep questionnaire will be conducted.

Assessment

Primary outcomes

The subjective sleep quality parameters scored in the subjective sleep assessment (OSA-MA) will be averaged over 3 or 2 nights at weeks 4, 8, and 12 of the labree and placebo intake periods, respectively, to assess changes over time and intervention effects.

Key secondary outcomes

1. To evaluate the daily changes and intervention effects by calculating the average values of each sleep parameter (total sleep time, sleep efficiency, sleep onset latency, mid-wake time, total time and percentage of deep sleep time, etc.) for 3 or 2 nights at weeks 4, 8, and 12 of the B. labrata intake period and placebo intake period, respectively, and to explore the relationship between the intake of B. labrata and sleep. The relationship between the ingestion of Bacillus labrata and sleep will be examined in an exploratory manner.
2. Insomnia tendency and daytime sleepiness data (Athens Insomnia Scale, Epworth Sleepiness Scale Questionnaire), stress and cognitive function assessments will be compared with the results of 4 weeks and 8 and 12 weeks of Labret bacteria intake and placebo intake to evaluate daily changes and intervention effects. These two points will evaluate the effects of Bacillus labree intake on subjective sleep assessment, stress and cognitive function.

Interventions/Control_1

During the intervention period, Group A (30 participants) will conduct a stool sample to measure the intestinal microbiota as a pre-measurement, one day before the start of intake (week 0) and on the last day of week 12 of the first intervention period and on the day before the second intervention period and the last day of week 12.In addition, sleep control will be administered from 7 days prior to the start of intake until the day the study is completed.Each participant will also consume the assigned test product, either the test food containing Bacillus subtilis Lovre or placebo, for breakfast each day (no intake during the washout period), and record the intake daily (see Test Food Summary).In addition, a sleep diary will be kept daily during the intervention period.On the fourth, eighth, and twelfth weeks of the intervention period, objective sleep assessment using EEG and other bioelectrical potential measurements from bedtime to awakening, and subjective sleep assessment using a bedtime questionnaire and an OSA-MA (On Sleep Sensation upon Awakening) questionnaire will be conducted for three consecutive days (Tuesday, Wednesday, and Thursday in principle), and on the last morning of the three-day sleep assessment period, a subjective assessment of the last one month'sOn the morning of the last day of the three-day sleep evaluation period, a subjective evaluation of sleep status, etc. (Athens Insomnia Scale, Epworth Sleepiness Scale) will be conducted.Subjects will be asked to visit the hospital at Week 0 and Week 12 of the intervention period for blood tests and urine collection.

Interventions/Control_2

During the intervention period, Group B (30 participants) will have a stool sample to measure the intestinal microflora one day before the start of intake (week 0) as a pre-measurement, as well as on the last day of week 12 of the first intervention period and on the day before and last day of week 12 of the second intervention period.In addition, sleep control will be administered from 7 days prior to the start of intake until the day the study is completed.Each participant will also consume the assigned test product, either the test food containing Bacillus subtilis Lovre or placebo, for breakfast each day (no intake during the washout period), and record the intake daily (see the test food summary).In addition, a sleep diary will be kept daily during the intervention period.On the fourth, eighth, and twelfth weeks of the intervention period, objective sleep assessment using EEG and other bioelectrical potential measurements from bedtime to awakening, and subjective sleep assessment using the Pre-Bedtime Questionnaire and the Onset of Sleep Assessment (OSA-MA) will be conducted for three consecutive days (Tuesday, Wednesday, and Thursday, in principle), and on the last morning of the three-day sleep assessment period, a subjective assessment of the last one month'sOn the morning of the last day of the three-day sleep evaluation period, a subjective evaluation of sleep status, etc. (Athens Insomnia Scale, Epworth Sleepiness Scale) will be conducted.Subjects will be asked to visit the hospital at Week 0 and Week 12 of the intervention period for blood tests and urine collection.
