make most estrogen hormones, although the adrenal glands and fat cells also make small amounts of the hormones.
What are the target cells of estrogen?
Estrogens have multiple effects on the growth and development of cells in their target tissues, including
the uterus, ovary, breast, bone marrow and brain
. The hormone regulates the transcription of diverse genes in these tissues via the estrogen receptor, a nuclear transcription factor.
What is the strongest form of estrogen?
Out of the three forms of estrogen,
estradiol
is the most potent form. It is approved by the U.S. Food and Drug Administration to treat estrogen-related conditions. Estriol and estrone are not approved in the U.S. for women. However, these estrogens may still be used in some compounded medications.

irregular periods
.
light spotting
.
What is the bad estrogen?
Estriol is considered a weak estrogen as well. It has been postulated that
estrone
is a “bad” estrogen and may be the cause of estrogen’s cancer-causing properties, while estriol is a “good” estrogen and may protect against cancer. Estradiol is probably neutral.
What happens when your estrogen is high?
Heavy periods: Estrogen is responsible for
the thickening of the uterine lining
. With the rising levels of estrogen hormone, the uterus lining thickens, which leads to painful and heavy menstrual bleeding. Mood swings: Estrogen dominance can cause a range of mood swings, anxiety, panic attacks, and depression.
