Genistein is widely used in the field of medical research due to its potential health benefits. It is studied for its role in cancer prevention and treatment, particularly for breast and prostate cancers, as it has been shown to inhibit the growth of certain cancer cells by interfering with enzyme pathways that promote tumor development. Additionally, genistein is explored for its antioxidant and anti-inflammatory properties, which help in reducing oxidative stress, inflammation, and the risk of cardiovascular diseases. It is also being investigated for its effects on bone health and menopausal symptoms, particularly in postmenopausal women, as it may help in preventing bone loss and alleviating hot flashes associated with estrogen decline.

In the cosmetic industry, genistein is incorporated into skincare products for its anti-aging properties, as it can improve skin elasticity, stimulate collagen production, and reduce the appearance of wrinkles by protecting skin cells from free radical damage.

Furthermore, it is used in dietary supplements aimed at promoting overall health and well-being. In agriculture, genistein is studied as a plant growth stimulant and to enhance plant resistance to diseases and pests by improving the plant immune system.
