Genistin is a natural isoflavone isolated from legumnes, including soy and kedzu. It is a phytoestrogen, as it stimulates the growth of estrogen-dependent human breast cancer cells in vivo.
Like other isoflavones, genistin promotes the pro -liferation of bone marrow stromal cells and osteoblasts and supresses bone turnover. It also increases bone formation in collagen matrix in vivo.
