Consuming 200 milligrams of caffeine or more than one cup of soda and other caffeinated beverages will cause an increase in estrogen levels. The impact of this increase in estrogen levels was different between women with a female Asian Caucasian (white).

More than 250 women aged 18-44 years were included in the study carried out between the years 2005-2007. In general they mengasup 90 milligrams of caffeine per day, equivalent to a cup of coffee.

Those who consume caffeine 200 mg or more daily is known to increase estrogen. However the increase is not considered significant because it has not effect on the process of ovulation or the menstrual cycle.

Caffeine taken by the women came from coffee, soft drinks, black tea and green tea.
