Approximately 70% of all women experience hot flashes and/or night sweats (also called vasomotor symptoms or VMS) during the menopause transition. Although estrogen-containing hormone therapy is highly effective in managing these symptoms, various studies have raised concerns regarding the risks associated with prolonged use of hormone therapy and many women now use other non-hormonal options to manage their symptoms, including over-the-counter complementary and alternative medicines (CAMs), including soy isoflavones, black cohosh, and omega-3 fatty acids. However, the data regarding the effectiveness of these alternative treatments has been mixed.
Soy-based products have long been touted as a treatment for menopausal symptoms. However, many of the clinical studies measuring the effectiveness of dietary sources of soy isoflavones (e.g., soy beverages, soy powder) for the treatment of menopausal vasomotor symptoms (i.e., hot flushes, night sweats) have been negative. Less is known about the effects of soy on cognition. A large clinical trial suggests that soy may not have any positive effects on cognition in postmenopausal women.
Approximately seventy percent of all women experience hot flashes and/or night sweats (also called vasomotor symptoms) during the menopause transition (Stearns et al. 2002). Until recently, estrogen therapy was the treatment of choice for most women who sought treatment for hot flashes. Since the results of the Women's Health Initiative in 2002 noted risks of prolonged use of hormone therapy in older postmenopausal women (Roussouw et al. 2002), many women pursue other treatments for their hot flashes, including over-the-counter complementary and alternative medicines (CAMs), including soy isoflavones, black cohosh, and omega-3 fatty acids. However, there is limited evidence to support the use of these treatments for hot flashes to date.
