Menopausal symptoms: Hot flashes, neck and shoulder stiffness

Hot flashes (feeling hot, sweating, etc.), neck and shoulder stiffness, and fatigability are reported as characteristic symptoms of menopause. A study was conducted to test the effectiveness of equol against these symptoms.

Study outline and results

126 non-equol producing, post-menopausal women experiencing hot flashes, between the ages of 45 and 60, were either given 10mg/day of equol or a placebo treatment for 12 weeks.

As a result, the group that received equol treatment reported a 50% reduction in the frequency of hot flashes and an amelioration of neck and shoulder stiffness.
