There is no such thing as a cup of soymilk a day to supplement estrogen, only for the body to supplement nutrition.
Soymilk is made from soybeans, isoflavones in soybeans and estrogen have similarities, there is a slight similarity to the role of estrogen; but the isoflavones in soymilk are within the safe range, and the daily intake of soymilk is limited, so simply drinking soymilk can not be supplemented with estrogen for the human body, there is no one cup of soymilk a day how long to supplement estrogen said.
Soymilk can only supplement the body protein, trace elements, such as the existence of estrogen is too low, or need to use estradiol valerate, combined with estrogen and other hormone drugs under the guidance of the doctor for treatment.
Soymilk is just a common food, does not have the effect of estrogen supplementation, if there are special circumstances, it is recommended to consult a medical professional.
