■ Research content and results
　 In this study, the subjects were divided into two groups, a food intake group containing 3,000 mg Euglena and a placebo food intake group * 3, and four time points before the start of intake, 2 weeks after intake, 4 weeks after intake, and 2 weeks after the end of intake. So, I measured the brain waves during sleep. The subject stayed at the same facility and went to bed and woke up at the designated time.
* 3 A test meal that is indistinguishable from the test meal by blending a substance that does not easily affect the human body instead of the test substance.

Euglena intake has been suggested to be involved in sleep depth
　The subject's sleep status was monitored by measuring the brain waves during the subject's sleep. From the pattern of brain waves, sleep is divided into three stages of light sleep, deep sleep, and REM sleep (sleep stage) "* 4, and as a result of measuring the number of occurrences of each, Euglena continuously for 4 weeks, The number of deep sleeps increased significantly compared to before the start (figure below). In addition, two weeks after the end of intake, the number of occurrences of deep sleep returned to a level close to that before the start of intake. This result suggests that continuous intake of Euglena
* 4 When you fall asleep, you first go into deep sleep, and after about an hour, your sleep gradually becomes lighter, and then you move to REM sleep. This cycle of about 90 minutes is repeated 3 to 5 times a night. It is generally said that you dream during REM sleep, and it is known that deep sleep affects sleep satisfaction.

　In addition, the sleep quality evaluated by the St. Mary's Hospital Sleep Questionnaire * 5 also showed a tendency to improve by taking Euglena for 4 consecutive weeks, similar to the deep sleep confirmed from brain waves.
　This study Euglena intake may improve sleep satisfaction through deeper sleep.
　At our company, we will further elucidate the potential of Euglena that supports the cycle of "making, working, and protecting" that the body originally has, Euglena and its ingredients in health foods, medical fields, etc. and add them as foodstuffs. We will carry out research and development with the aim of increasing value.
* 5 Answer the degree of sleep depth, mid-alertness, deep sleep, sleep satisfaction, refreshment when waking up, difficulty falling asleep, and presence / absence of early awakening from the options, and evaluate the quality of sleep based on the total score. Questionnaire for
