Description of Estriol :
Estriol can be a weak or strong estrogen depending on if it is given acutely or chronically when given to
immature animals, but is an antagonist when given in combination with estradiol.
Estriol may play a role in the development of breast cancer, but based on in vitro research, does appear
to act as an antagonist to the G-protein coupled estrogen receptor. Though estriol is used as part of
the primarily North American phenomenon of bioidentical hormone replacement therapy, it is not
approved for use by the FDA or Health Canada.
