Research has confirmed that the Lactobacillus Casei Strain Shirota plays a role in suppressing sympathetic nervous activity, specifically inhibiting the excessive sympathetic activity that increases due to stress, but it does not affect normal sympathetic activity. Related studies indicate that this product helps relieve stress and improve sleep quality (increasing sleep depth), allowing one to feel refreshed upon waking, but it does not induce sleep.

The safety of the product for consumption has been confirmed, so you can drink it with peace of mind. Healthy eating habits should start from a young age, and daily supplementation of the Lactobacillus Casei Strain Shirota lays a good foundation for gut flora balance. It can be started from 6 months after birth (for weaning infants) and should be diluted with low-temperature water to about twice the amount while observing the infant's health status. Gradually increase the feeding amount bit by bit each time. However, please note that children may not fully understand the effects of stress relief or improved sleep based on individual circumstances.

For hygiene considerations and to ensure product quality, please consume the product quickly after opening the cap, and it is not recommended to drink from the same bottle multiple times. Additionally, for a better experience, it is advised to drink one bottle per day and make sure to finish it all at once. The research tests are based on a daily intake of one bottle, so if two people each drink half (50ml), it may not achieve the optimal effect experience.

Research indicates that the Lactobacillus Casei Strain Shirota helps suppress the sympathetic nervous activity that increases due to stress. Additionally, studies show that it stimulates the connection between the brain and gut nerves, which can inhibit excessive stress responses.

The study surveyed a group of medical students in their twenties who were about to take exams, observing the physical changes after continuously consuming a drink containing 100 billion Lactobacillus Casei Strain Shirota. Regarding improvements in sleep quality, there is no age difference; generally, it is effective for adults under stress. However, whether to invite different participants in the future to experience the product's functions (stress relief, improvement in sleep quality) will be one of the considerations for future research.

Through multiple tests, no adverse reactions have been observed among participants with a continuous intake of 100 billion or more LcS, indicating that the product has a certain level of safety.

Y1000 (Yakult 1000) is a health drink that is generally safe to consume. However, it is recommended that you consult your family doctor or pharmacist based on your health condition before consumption. This product is not a substitute for the medical effects of any medication.
