| Outline of Final Research Achievements |
Soy isoflavones and equol (EQ), which is a metabolite of isoflavone daidzein, have an ability to cause weak estrogenic effects, and EQ have been reported to improve vasomotor symptoms, such as shoulder stiffness and hot flush, and osteoporosis in menopausal women. The objective of this study is to examine the ability of EQ to prevent the decrease of blood flow, which is the index of vasomotor symptoms as well as bone loss induced by oestrogen deficiency in ovariectomised (OVX) rat.
Dietary supplementation with EQ prevented the decrease of blood flow and bone loss induced by estrogen deficiency in OVX rats. These results raise the possibility that dietary supplementation with EQ may relieve vasomotor symptoms and osteoporosis in postmenopausal women.
