Objectives
Narrative objectives1
Subjective evaluation of cognitive function using a cognitive function evaluation application will be conducted in healthy Japanese adult males and females aged 18 to 80 years old who have some problems or troubles with sleep in order to clarify the effects of Labret's Bacillus subtilis intake on cognitive function.

Assessment
Primary outcomes
Evaluate the relationship between the various parameters of the MIRUDAKE cognitive function assessment application for each subject and the presence or absence of the test food intake.
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 assessment will be compared with the results of 4 weeks and 8 and 12 weeks of Labret bacteria and placebo intake to evaluate daily changes and intervention effects.These two points will evaluate the effects of Bacillus labre intake on subjective sleep assessment, stress and cognitive function.

Interventions/Control_1
During the intervention period, Group A (30 participants) will perform 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.Each of the assigned test products will be consumed daily with breakfast, either the test food containing Bacillus labre or a placebo (no consumption during the Washout period), and the consumption will be recorded daily (see Test Food Summary Form).In addition, at weeks 4, 8, and 12 of the intervention period, objective evaluation of sleep using EEG and other bioelectrical potential measurements from bedtime to awakening, and subjective evaluation of sleep using a bedtime questionnaire and an OSA-MA (On Sleep Sensation upon Awakening) questionnaire were conducted for 3 consecutive days (Tuesday, Wednesday, and Thursday, in principle), and on the morning following the last day of the 3-day sleep evaluation period, the most recentSubjective assessment of sleep status and other factors (Athens Insomnia Scale, Epworth Sleepiness Scale) and stress (PSS, STAI) for one month will be conducted on the morning following the last day of the three-day sleep assessment period.An eye tracking cognitive function assessment test will be conducted on the day of the first visit at week 0 of the intervention period and on the day of the second visit within 3 days of the last day of the 12-week period.Subjects will be asked to visit the hospital at Weeks 0 and 12 of the intervention period for blood tests and urine collection.
Interventions/Control_2
During the intervention period, Group B (30 participants) will perform 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.Each of the assigned test products will be consumed daily with breakfast, either the test food containing Bacillus labre or a placebo (no consumption during the Washout period), and the consumption will be recorded daily (see Test Food Summary Form).In addition, at weeks 4, 8, and 12 of the intervention period, objective evaluation of sleep using EEG and other bioelectrical potential measurements from bedtime to awakening, and subjective evaluation of sleep using a bedtime questionnaire and an OSA-MA (On Sleep Sensation upon Awakening) questionnaire were conducted for 3 consecutive days (Tuesday, Wednesday, and Thursday, in principle), and on the morning following the last day of the 3-day sleep evaluation period, the most recentSubjective assessment of sleep status and other factors (Athens Insomnia Scale, Epworth Sleepiness Scale) and stress (PSS, STAI) for one month will be conducted on the morning following the last day of the three-day sleep assessment period.An eye tracking cognitive function assessment test will be conducted on the day of the first visit at week 0 of the intervention period and on the day of the second visit within 3 days of the last day of the 12-week period.Subjects will be asked to visit the hospital at Weeks 0 and 12 of the intervention period for blood tests and urine collection.
