The gut microbiome in hormonal health: What’s the estrobolome?

Hormones influence many systems in the body, including mood, metabolism, skin, energy, digestion and reproductive health. And, while the ovaries and adrenal glands are well known for producing hormones, the gut too has a role.

A specific part of the gut microbiome, known as the estrobolome, is responsible for managing how oestrogen is processed, reused and removed. So, when this system functions smoothly, hormones are easier to regulate.

But if it falls out of balance, the effects can show up across multiple aspects of female health concerns.

What the estrobolome does

Put simply, the estrobolome is made up of certain gut bacteria and their genes that influence how oestrogen is broken down and cleared from the body.

It helps determine how much oestrogen remains active and how much is safely removed through elimination.

Because oestrogen has such a big role, this bacterial system also contributes to mood stability, libido, cognitive clarity, metabolic function and skin health.

Why the estrobolome matters for women’s hormonal health

Throughout life, oestrogen levels rise and fall in response to cycles, pregnancy, contraceptives and ageing.

At every stage of life, effective hormone clearance is what is required for maintaining optimal hormonal balance.

The estrobolome and the liver

The estrobolome works with the liver to neutralise and remove used oestrogen.

But, if that process slows down or becomes disrupted, oestrogen may be reabsorbed rather than excreted.

As a result, you might notice changes in mood or energy, more pronounced sensitivity to environmental or hormonal triggers, or an increase in issues related to oestrogen dominance such as PMT, fibroids or skin breakouts.

Moreover, a hormone clearance that’s sluggish can also contribute to low energy.

Even in midlife, when hormone levels naturally begin to change, supporting the estrobolome can be very helpful in easing the symptoms which can arise during this transition.

What’s beta-glucuronidase?

The enzyme called beta-glucuronidase is produced by specific gut bacteria.

In a healthy microbiome, this enzyme supports hormone elimination. But if gut bacteria become imbalanced, beta-glucuronidase levels can rise and interfere with the process.

Instead of being removed, oestrogen may re-enter circulation, which can add to hormonal symptoms and place extra load on the body’s detox systems.

6 ways to support a healthy estrobolome

1. Include prebiotics and probiotics: Fermented foods and fibre-rich plants can encourage a more balanced, stable gut environment. Targeted probiotics like YourGut Restore also contain prebiotic formulas help to create a stable bacterial environment in the gut.
2. Eat more fibre to support the gut: Plant fibres from vegetables, legumes and whole grains also help nourish the beneficial bacteria that support hormonal health.
3. Support the liver: Epavin supports the estrobolome by combining botanicals traditionally associated with liver, bile, and digestive support, encouraging healthy detoxification and oestrogen clearance through the liver-gut pathway.
4. Reduce highly processed foods: Ultraprocessed food is generally high in gut-harming additives like preservatives and sweeteners and low in fibre, this can disrupt microbial diversity and affect hormone balance.
5. Use probiotics after antibiotics: While they can be necessary to recover from serious infections, antibiotics can reduce gut bacterial diversity and therefore disturb hormone metabolism. Be sure to use probiotics to promote the health of the microbiome after antibiotic use has occurred.
6. Balance movement and rest: Regular physical activity helps regulate gut function and hormone-related systems, while rest and quality sleep are important to avoid burnout and support the health of the gut.

Adapt with hormonal changes in menopause

During midlife, your gut microbiome may naturally change, due to many changes occurring in the body. Therefore, supporting the health of the microbiome during this phase can help hormones stay more balanced.

Nutrients that support gut and hormone health:

Certain nutrients can play a helpful role in supporting both hormone metabolism and gut function. These are some of the key vitamins, minerals and compounds that work together to keep your estrobolome and your hormones functioning at their best.

Magnesium and vitamin B6 assist liver detox pathways involved in hormone metabolism. Shop Pure Encapsulations Magnesium (Citrate/Malate) and B6 Complex.

Selenium supports the thyroid, which influences broader hormone activity. Supplemental complexes, such as Pure Encapsulations Thyroid Support Complex, contain selenium for this reason.

Zinc may help regulate beta-glucuronidase, keeping oestrogen clearance on track. Health Ionic Zinc Liquid Concentrate contains a naturally occurring, ionic mineral form of zinc that is designed to restore at the cellular level.

Ashwagandha supports the stress response, which in turn benefits gut stability. Living Nutrition uses the ancient art of fermentation, providing their ashwagandha supplement in an energetic form.

Curcuminoids help calm inflammation in the gut environment, by calming overactive immune responses and supporting the gut lining. Myconutri-Curcumin Complex contains curcumin with the added benefits of medicinal mushrooms.

Vitamins D3 and K2 support bone health, while iron and B12 help maintain energy and cognitive clarity. Chromium supports blood sugar stability, which can be an important part of hormonal regulation. All of these nutrients can be found in Pure Encapsulations O.N.E. Multivitamin.

Takeaways

The estrobolome is an essential part of women’s hormonal health, yet it is often given very little air-time.

By helping to regulate oestrogen, this system influences everything from energy and mood to metabolism and reproductive wellbeing.

With the right support, your gut and hormones can work together to keep you feeling balanced and resilient across all stages of life.
