Detox Pathways Under the Microscope: Why They Matter for Hormonal Balance
If you’ve ever wondered why some people struggle with PMS, heavy periods, hot flushes, or hormonal symptoms even when their blood tests look “normal,” the answer may lie in how their body processes hormones — particularly in the liver.
Hormones are powerful messengers, but once they’ve done their job they must be broken down and safely excreted. That “detox” process happens in two main phases. When these phases fall out of sync, hormones can build up in the body or get stuck in more reactive, potentially harmful forms.
The Two Phases of Hormone Detox
- Phase 1 (activation): Liver enzymes modify hormones (like oestrogen) into intermediate forms. These intermediates are often more active or damaging than the originals.
- Phase 2 (conjugation): The body attaches molecules (like methyl groups, sulphate, or glutathione) to neutralise those intermediates and make them easy to excrete through bile or urine.
When Phase 1 is running ahead of Phase 2, those “half-processed” hormones can pile up — a recipe for hormonal chaos.
The Hormonal Symptoms of Phase Imbalance
Research is highlighting how a mismatch between these detox phases can contribute to:
- Oestrogen dominance — linked to PMS, breast tenderness, heavy or irregular bleeding, and perimenopausal symptoms
- Hormone-sensitive conditions — such as fibroids or endometriosis, which can flare with impaired detox capacity
- Hot flushes and mood swings — worsened when oestrogen breakdown intermediates circulate longer than they should
- Greater sensitivity to medication or the pill — when detox pathways are overloaded or out of sync
What the Research is Saying
- Cruciferous vegetables (broccoli sprouts, kale, Brussels sprouts) provide sulforaphane and indole-3-carbinol, compounds shown to shift oestrogen metabolism toward safer pathways by boosting Phase 2 enzymes.
- Glutathione support through N-acetyl cysteine (NAC) and glycine helps neutralise reactive hormone intermediates and reduce oxidative stress.
- Methylation nutrients like folate, B12, and betaine are essential for breaking down oestrogen and balancing homocysteine.
- Lifestyle stressors such as alcohol, poor sleep, and chronic stress can accelerate Phase 1 and slow Phase 2, increasing hormonal symptoms.
Everyday Strategies for Hormonal Detox Support
- Load up on cruciferous veg (broccoli, cabbage, rocket) a few times a week.
- Ensure enough protein for amino acids that drive Phase 2 detox.
- Prioritise B vitamins (especially folate and B12) through leafy greens and/or supplements.
- Reduce alcohol, which places heavy demand on liver detox.
- Support stress resilience and sleep, both critical for hormonal balance.
The Bigger Picture
Hormonal symptoms are rarely “just in your head.” They often reflect deeper imbalances in how the body is processing and eliminating hormones. Functional medicine research into detox pathways is showing why some people experience more severe symptoms — and, more importantly, what we can do about it.
By supporting both phases of detox, we’re not only reducing uncomfortable symptoms — we’re protecting long-term hormonal health and building resilience for the years ahead.
We believe every woman deserves to feel at home in her own body. Our hormonal workshops are all about giving you the tools and confidence to take charge of your hormone health, whatever stage of life you’re in.
