The Therapeutic Role of Genistein in Perimenopausal and Postmenopausal Women.

Objective: We sought to review the biology and clinical benefits of genistein, a plant-derived isoflavone with emphasis on perimenopausal and postmenopausal women. The focus is on assessing its impact on skin health and aesthetics as well as bone density and cardiovascular and metabolic functions.

Methods: This narrative review used PubMed to collect studies relating to the biology and clinical effects of genistein on postmenopausal signs and symptoms, including bone density loss, metabolic issues and symptoms, and skin aging. Articles were selected based on relevance to the scope of genistein's influence on estrogen receptors and their downstream effects. This review included in vitro, in vivo, animal, and human studies.

Results: According to the current literature, genistein demonstrates efficacy in mitigating menopausal signs and symptoms such as hot flashes, bone density loss and rate of osteoporosis, and skin aging. It shows a protective effect against cardiovascular diseases by improving lipid profiles, weight changes, and reducing low-density lipoprotein cholesterol. It also displays benefits in increasing bone mineral density but has not displayed the side effects commonly associated with estrogen replacement. Regarding skin health, genistein appears to enhance photoprotection, wound healing, elasticity, and hydration, inhibits skin cancer, and reduces wrinkles.

Conclusion: Genistein acts as a selective estrogen receptor modulator (SERM) with benefits across a spectrum of menopausal signs and symptoms, presenting a viable alternative to estrogen replacement in perimenopausal and postmenopausal women. Its utility extends to improving cardiovascular health, bone density, and skin quality, making it a comprehensive treatment option for peri and postmenopausal women.
