大豆イソフラボンと黒豆ポリフェノールの研究成果

This document reports the results of a study conducted by Fujicco Co., Ltd. in collaboration with Professor Naoko Ishiwata. The research confirmed that the combined intake of soy isoflavones and black soybean polyphenols improves sleep quality in women around menopause. A clinical trial involving 104 women showed that the group taking the combined supplements experienced significant improvements in subjective sleep quality, sleep duration, shoulder stiffness, and eye fatigue. These findings will be presented at the 40th Annual Meeting of the Japan Society for Women's Medicine scheduled for November 2025.
