Soybean isoflavone is a plant hormone, which is extracted from soybean and has the same structure and estrogen-like activity as estrogen. Soybean isoflavone has magical two-way regulation effect. It can exert a weak estrogen-like effect on people with low estrogen level, and can prevent some diseases related to the decline of estrogen level, such as menopause, osteoporosis, premature ovarian failure, loose and rough skin, wrinkles and increased pigmentation. For those with high estrogen level (such as breast cancer patients), it shows anti-estrogen activity and can prevent breast cancer and endometrial cancer.
