In this blog we discuss the importance of estrogen detoxification for overall hormone health. We cover everything you need to know about the basics of estrogen detoxification, why it is so important and how you can begin to support it at home.
Key Takeaways
- Estrogen has many vital roles to play in the body including the regulation of female reproductive organs, brain health and supporting the nervous system.Â
- Estrogen dominance or unopposed estrogen is linked to symptoms such as painful, heavy and irregular periods.Â
- The most common causes of unopposed estrogen are poor estrogen detoxification, low progesterone and genetic SNPs or variations.Â
- Perimenopause, in its early stages, can see high levels of fluctuating estrogen, making estrogen metabolism an important consideration.
- Estrogen detoxification takes place in 3 distinct phases.Â
- The FUTURE WOMAN hormone tests all look at estrogen metabolism and detoxification. Each test comes with a 12 week personalised plan with supplement, diet and lifestyle recommendations to address your results.
- Two women with the same symptoms may need different protocols due to differences in estrogen detoxification.Â
- We recommend one thing all women can do from home to support estrogen metabolism.
The role of estrogen
So you may have heard of estrogen and all of her wonderful qualities. Luckily for us, estrogen is all about being bright, vibrant and sexy. Some of the roles estrogen plays in the body include:
- Development and regulation of the female reproductive organsÂ
- Growth and maintenance of the skeleton
- The normal function of the cardiovascular and nervous systems
- Important for metabolic health, muscle mass and preventing insulin resistance
- Supports brain health
The negative sides of estrogen
Although estrogen has many benefits for the body and brain, you may also have heard about the negative sides of estrogen. For example, when you have unopposed or excess estrogen and its link to some of the following symptoms:
- Heavy periodsÂ
- Painful periodsÂ
- Severe PMS
- Mood changesÂ
- Breast pain or tendernessÂ
- Weight gainÂ
- DepressionÂ
- Fertility issuesÂ
- Irregular periodsÂ
- EndometriosisÂ
- FibroidsÂ
Unopposed estrogen can become a problem when we have low progesterone, high estrogen production and poor estrogen detoxification.
What is estrogen?
Estrogen is one of the two main female sex hormones (the other being progesterone).Â
There are three main estrogens:
- Estrone (E1) – this is the main estrogen in menopausal yearsÂ
- Estradiol (E2) – this is the main estrogen in reproductive years
- Estriol (E3) – this is the main estrogen that your body makes in pregnancyÂ
As we discovered, estrogen has many important roles to play in the body; primarily estrogen is responsible for the development and regulation of the female reproductive organs.
Estrogen and your menstrual cycle
Estrogen takes centre stage in the follicular phase or first phase of your menstrual cycle. This is the phase between your period and ovulation. Having balanced estrogen is extremely important in your cycle as it is responsible for growing and maintaining the uterine lining and also for maturing the egg prior to ovulation.
Estrogen levels act as a signalling system during your cycle; for example, when estrogen reaches a certain level in the follicular phase, this sends a message for the brain to release luteinising hormone (LH) which in turn causes ovulation to occur. Therefore, balanced estrogen levels are vital for a healthy menstrual cycle.
What is estrogen dominance?
One of the most common hormonal imbalances is what we call estrogen dominance, estrogen excess or unopposed estrogen. This means that estrogen levels are too high relative to progesterone (this can also include testosterone). The most common causes for this are:
- Poor estrogen detoxification – impaired estrogen detoxification at phase 1, 2 or 3 can lead to estrogen being reabsorbed and reactivated instead of being removed from the body.Â
- Genetic SNPs – there may be variations on some of your genes that encourage the production of estrogen (eg: CYP19A1), or that impede healthy estrogen detoxification such as the COMT gene.
What is estrogen detoxification and why is it so important?
Estrogen detoxification occurs in three stages. The first two stages occur in the liver and the third predominantly in the gut.
Phase 1 estrogen detoxification
As mentioned, estrogen detoxification happens in two phases. In Phase 1, there are enzymes called the CYP family of detoxification enzymes which take estrogens through a process called hydroxylation and prepares them for Phase 2 detoxification. What this basically means is that in phase 1 estrogen is broken down and transformed so that it is ready for phase 2. After undergoing these processes in phase 1 it can leave the estrogen more ‘toxic’. This means that it is very important that phase 2 is working properly to neutralise this estrogen again for removal in the body.
Within phase 1 detoxification there are three different pathways that estrogen can move through.Â
- 2OH – this is the most favoured pathway.Â
- 4OH – this is the least favoured pathway and can be more carcinogenic because it has more risk for DNA damage.
- 16OH –Â This pathway has the strongest binding effects to estrogen receptors. Therefore it is considered to be the most proliferative. This means this pathway may cause symptoms such as heavy periods, tender breasts and painful periods.
An extract from the FUTURE WOMAN Classic Hormone Test shows optimal Phase 1 detoxification.Â
Testing and understanding which pathway your estrogen is predominantly moving through is vital, especially if you have signs of high estrogen.
Phase 2 estrogen detoxification
Phase 2 of estrogen detoxification helps to prepare the estrogen to be removed from the body by making it water soluble so it can be removed easily.Â
Methylation is one of the processes that occurs in phase 2. Methylation, commonly termed ‘one-carbon metabolism’, is an important biochemical process that involves the transfer of active methyl groups to functions or processes that need them.Â
To put this simply, methylation of estrogen is the transformation of estrogen so it can be removed. Therefore the process of methylation needs to be working well to support healthy estrogen detoxification.
Poor methylation status can be caused by many factors such as:Â
- Poor nutrient status (such as folate or B12)
- Genetic variants on genes such as COMT or MTHFRÂ
- Other factors such as stress.Â
If there is poor methylation status in the body it can lead to hormone imbalance, poor detoxification, poor sleep, mood changes and low energy. We can test your methylation status in relation to estrogen detoxification in all of our FUTURE WOMANÂ hormone tests.

Phase 3 estrogen detoxification
Phase 3 estrogen detoxification is all about the safe removal of estrogen from the body via bile, urine and stool.Â
Once estrogen has been through phase 2, it’s packaged up (and made water-soluble) and pushed into the bile and then into the gut where it leaves via the stool.
It is important to ensure phase 3 is working properly, as if it is not it can lead to the unpacking of your estrogen (by an enzyme called beta-glucoronidase) and can lead to your estrogen being reabsorbed in the body again = resulting in high estrogen.
Estrogen detoxification and perimenopause
Estrogen detoxification becomes an important consideration in perimenopause because in the early stages of perimenopause, estrogen can fluctuate higher than at any other time in a woman’s reproductive life. Women in perimenopause are also more likely to be given the Mirena IUD or hormonal IUD, which can lead to temporary estrogen dominance if progesterone levels are suppressed due to lack of ovulation.Â
Estrogen detoxification and HRT
If you are on or considering estrogen hormone replacement therapy, then monitoring your estrogen levels and estrogen metabolites via our Advanced Hormone Test is important to make sure you’re metabolising the additional estrogen safely and efficiently.Â
Testing estrogen detoxification
All three of our FUTURE WOMAN hormone tests provide insights into your current hormone levels and also how effectively your body is able to metabolise them. This is important when understanding why estrogen may be high as it helps to assess your entire hormone health picture, from production of hormones to the way they are removed from the body.Â
Included within each test is a 12 week personalised plan, prepared by one of our expert nutritionists, which includes supplement, diet and lifestyle recommendations.Â
Next steps
If you’re experiencing symptoms of high estrogen or poor estrogen metabolism, it’s important to test estrogen alongside markers for estrogen metabolism to get the full picture.Â
Depending on your results, our expert nutritionists can recommend targeted support. For example, certain antioxidants have been shown to be effective in redirecting estrogens from the prolifierative 16-OH-E1 pathway, to the more favourable 2-OH-E1 pathway.
What is important to note is that estrogen metabolism is very individual, and two women with the same symptoms may need very different protocols due to subtle differences in the way they metabolise estrogen.Â
One thing that can benefit all women struggling with symptoms of estrogen dominance is to reduce or eliminate alcohol. Alcohol can impact the quality of all three phases of estrogen detoxification.Â
