Several forms of estrogen occur naturally in a woman's body. The ovary produces a form named estradiol, which is converted into another important estrogen called estrone. Estriol is yet another form of estrogen metabolized from estradiol, weaker than the other two, but still active.
Estriol is manufactured in the body from estrone, estradiol, and androstenedione . When taken as a drug, it is manufactured synthetically, or extracted from animal products.
The usual dose of estriol is 2 to 8 mg taken once daily. Estriol is also commonly sold in combination with other forms of estrogen.
