Do you suffer from sleep problems such as "I don't sleep as well as I used to" or "I haven't been waking up well lately..."? In fact, such sleep problems can occur to anyone as they age. Suntory has developed "Kaiyumi Sesamin," which contains sesamin and theanine, based on the fact that the body constitution becomes more difficult to sleep well as one ages. Sesamin, which removes rust from the body, improves the quality of sleep*, while theanine, which regulates the nervous system to regulate the body and mind, reduces fatigue upon waking. Recommended for those who want to spend a full and 100% productive day from the morning.
