Mechanism of action

17Beta-estradiol is the primary form of estrogen that binds to estrogen receptors (ERα and ERβ) throughout the body, while progesterone acts on progesterone receptors to provide endometrial protection and additional hormonal effects. Together, they mimic the natural hormonal cycle and alleviate menopausal symptoms while reducing certain long-term health risks associated with estrogen deficiency.
