What Is The Difference Between A Woman's Hormones And Biologically Identical Hormones?
The following illustration show the molecular structure of a woman’s estrogen on the left and biologically identical [bio–identical] estrogens on the right.
| Human Estrogens | Biologically Identical [Bio–Identical] Estrogens |
 |
|
The following tables show the amounts of each type of estrogen that a woman’s body makes, and the amounts of each type of estrogen in compounded biologically identical [bio–identical] estrogens.
| Human Estrogens | Tri–Est [all 3 estrogens] | ||
| Estrone [E1] | 10 – 20% | Estrone | 10 – 20% |
| Estradiol [E2] | 10 – 20% | Estradiol | 10 – 20% |
| Estriol [E3] | 60 – 80% | Estriol | 60 – 80% |
| Human Estrogens | Bi–Est [2 estrogens] | ||
| Estradiol [E2] | 10 – 20% | Estradiol | 20% |
| Estriol [E3] | 60 – 80% | Estriol [E3] | 80% |
The following illustration show the molecular structure of a woman’s progesterone on the left and biologically identical [bio–identical] progesterone on the right.
| Human Progesterone | Biologically Identical [Bio–Identical] Progesterone |

|
As can be seen from the illustrations, biologically identical [bio–identical] estrogens and biologically identical [bio–identical] progesterone have exactly the same molecular structure as the estrogens and the progesterone that a woman’s body makes.
