This product is a supplement containing sake yeast GSP6 as a functional ingredient, focusing on sleep quality (deep sleep) and morning drowsiness. Sleep quality, not just quantity, is important. Clinical trials demonstrate an approach to "deep sleep." In response to the sleep concerns of many modern individuals, the new product "Gussuri Mameko" focuses not just on securing sleep time, but on enhancing the "quality" of sleep itself. A clinical trial conducted on healthy adults dissatisfied with their sleep showed that when "sake yeast GSP6," the ingredient in this product, was consumed, the "Stage 1 delta wave power value," known as an indicator of deep sleep, significantly increased by 110% compared to a placebo. Reliable data supporting the daily support of "deep sleep power" was confirmed. Furthermore, in the same clinical trial, as part of research on the body's rhythm during sleep, "urinary growth hormone levels upon waking" were measured and showed a significant increase of 137% compared to the placebo.
