There are the 3
bio-equivalent estrogens:
- Estrone (E-1)
- Estradiol (E-2)
- Estriol (E-3)
These three chemicals
make up human estrogen. The estrogen that has the most volume in the
body is estriol (60-80% of circulating estrogens), followed by estradiol
and estrone (10-20% each). Estriol is thought to be the weakest acting
hormone, but provides a natural hormonal balance in the body, whereas
estradiol and estrone are thought be the stronger estrogens. The female
body produces large amounts of estriol during pregnancy and has
protective properties against such things as estrogen related cancers. Estradiol
is the estrogen that can relieve vaso-motor symptoms the best. Estrone
is the primary estrogen found in post-menopausal women. It stores it
self in the body fat and has more know cancer properties.
