Estrogen is often referred to as the hormone of femininity, but its role is much broader. From emotional balance and bone health to fertility, metabolism, and even the risk of chronic diseases, estrogen profoundly influences a woman’s body. However, an imbalance, whether in excess or deficiency, can lead to a wide range of disorders.
What is Estrogen?
Estrogen is a steroid hormone primarily produced by the ovaries, but also by the adrenal glands and adipose tissue. There are three main forms of estrogen:
- Estradiol (E2) – the most active estrogen, predominant in women during their fertile years.
- Estrone (E1) – the main estrogen after menopause.
- Estriol (E3) – present during pregnancy, with a protective role.
The Benefits of Estrogen Explained in Detail
1. Regulation of the Nervous and Emotional System
Estrogen regulates the synthesis of serotonin and dopamine, neurotransmitters involved in well-being. Adequate levels support emotional balance, combat depression and anxiety, and improve memory.
2. Cardiovascular Protection
It has vasodilatory and anti-inflammatory effects, reduces LDL cholesterol (bad) and increases HDL (good), protecting blood vessels and reducing the risk of coronary diseases.
3. Bone Health
Estrogen inhibits bone resorption and stimulates the formation of new bone tissue. A deficiency of estrogen is the main cause of postmenopausal osteoporosis.
4. Maintenance of Feminine Characteristics
Estrogen supports skin health, breast growth, vaginal lubrication, skin elasticity, and the feminine voice.
5. Fertility and Menstrual Cycle
Estrogen coordinates the first part of the menstrual cycle and supports the development of the endometrium (uterine lining), essential for conception.
When Does Estrogen Become a Problem?
Estrogen Deficiency (Hypoestrogenism)
Occurs in:
- menopause,
- polycystic ovary syndrome (sometimes),
- thyroid disorders,
- anorexia or very low weight.
Symptoms: hot flashes, vaginal dryness, depression, insomnia, irregular menstruation, loss of bone mass.
Excess Estrogen (Estrogen Dominance)
Can occur even when estrogen levels are normal, but progesterone is too low.
Symptoms: painful cycles, breast tenderness, hormonal migraines, water retention, uterine fibroids, ovarian cysts, anxiety, fatigue, increased risk of breast and uterine cancer.
How to Naturally Balance Estrogen?
For Deficiency:
- Flaxseeds – rich in lignans, balance estrogen levels.
- Maca root – a hormonal adaptogen.
- Soy isoflavones – phytoestrogens with a protective role.
- Evening primrose or borage oil – supports hormonal synthesis.
For Excess:
- Avoid ultra-processed foods and meat from hormone-treated sources.
- Support liver detoxification (with milk thistle, artichoke).
- Consume fiber to eliminate excess estrogen.
- Use herbs such as celandine, fenugreek, sage – which help regulate estrogen levels.
Contraindications and Warnings
- Phytoestrogens should not be administered without medical advice in cases of breast or uterine cancer.
- Hormone replacement therapy must be closely monitored, as it increases the risk of thrombosis or cancer with prolonged use.
- Some natural supplements may contain synthetic estrogens – always check the source.
