Like many women, do you dread ‘that time of the month’? Do the highs and lows of premenstrual syndrome (PMS), pelvic pain or heavy flow hamper normal functioning around the time of your period? Did you know these symptoms (including hard-to-shift weight gain) may be related to imbalances in hormones such as oestrogen? This blog explores the important topic of oestrogen, as this hormone can be amazingly beautiful in our bodies, but when out of balance, it may also turn ugly.
Oestrogen is predominately thought of as a female hormone. Still, just as women have small amounts of the male hormone, testosterone – men also need some oestrogen (albeit at lower levels) for optimal health.
Oestrogen wears many hats, and they’re not all related to reproduction!
It also supports brain health. For example, it has been linked to slowing down the ravages of ageing and is protective against many neurological conditions such as Alzheimer’s disease, schizophrenia and depression.1 Oestrogen is also considered the beauty hormone; it plays a role in collagen production and moisture retention for supple skin,2 helping you look more youthful! She is part of why women retain hair on their heads but have thinner hair elsewhere. Oestrogen will also help bones remain strong by preventing calcium loss and supporting healthy cholesterol metabolism (see Figure 1).
Figure 1: The Many Effects of Oestrogen.
All that said, oestrogen’s primary function is as a reproductive hormone. Levels begin to increase in young girls in puberty, around the time their periods start. It is produced mainly by the ovaries and will go on to shape and grow the breasts and the uterus. It’s lining (the endometrium) – essentially preparing the female body for reproduction. Interestingly, males also rely on oestrogen for the all-important task of creating healthy sperm!
Fun Fact: Did you know that during pregnancy, oestrogen levels are 1000 times higher than in non-pregnant women? This increase helps to expand the uterus to make space for the developing foetus and prepares the breasts for lactation.3
Intracrinology – Intra What?
I know I mentioned earlier that oestrogen is produced primarily by the ovaries. Still, this sneaky hormone can also be synthesised in other tissues in the body, including the breast, the brain and even in body fat! Known as the science of intracrinology, studying hormone levels in different tissues can give some fascinating insights into oestrogen activity throughout the body. As shown in Figure 2 below, many factors (such as increased production in various tissues and impaired detoxification) can disrupt the delicate balance of hormones and, in some cases, lead to having too much.
Excess oestrogen may result in symptoms such as period pain, heavy flow, PMS and even more serious presentations such as endometriosis,4 fibroids5 and breast cancer.6

To give another example – if a woman is overweight, the extra fatty tissue can hold more oestrogen in the body, which can potentially lead to oestrogen excess and a worsening of hormonal symptoms. Learn about more ways hormones can become disrupted here.
Further, living in the modern world brings constant exposure to environmental toxins such as plastics and other chemicals; those with hormonal effects are known as endocrine-disrupting chemicals (EDCs). EDCs such as bisphenol A (BPA) found in the lining of tins can increase oestrogen and change how it works in the body. Read more about this here.
Be Proactive About Keeping Oestrogen in Balance
If your pain, PMS or hormonal symptoms may be caused by too much oestrogen, then it’s time to take back control. There are many positive steps you can take towards rebalancing your hormones.
Many herbs and nutrients can be highly beneficial in reigning in out-of-control hormones. Isoflavones from soy support women’s healthy oestrogen levels by modulating oestrogen receptors (the binding sites on the cells).7 This means that soy can effectively instruct cells to promote the healthy actions of oestrogen and turn down the dial on the more negative impacts. Read more about soy in this article. Natural medicines such as magnesium, broccoli, rosemary, and BCM-95™ Turmeric positively support healthy oestrogen metabolism, helping restore balance.
You can adopt some simple strategies daily to place you on the path of healthy oestrogen balance. Follow the healthy hormone dietary and lifestyle tips in Figure 3 below. Other suggestions include not microwaving food in plastic containers and swapping your plastic drinking bottles for glass or stainless steel – this can help reduce the impact of EDC’s exposure. For more simple tips to detox your environment, check out this blog.

By gradually changing your habits, you can reduce exposure to harmful EDCs, improve your oestrogen metabolism, and maintain the beneficial effects that the beautiful hormone called oestrogen may bring.
