I take probiotics every day. I also eat sauerkraut and fermented foods regularly — kimchi, kefir, live yoghurt — and I've made sure that my Daily Menopause Support contains live bacteria as part of the formula. This isn't an afterthought — it's intentional. The more I've learned about the gut-hormone connection, the more I've come to see gut health as one of the most important and most overlooked pillars of navigating menopause well.
What Happens to Your Gut During Menopause
As oestrogen declines during perimenopause and menopause, it doesn't just affect your periods, your mood, or your sleep. It directly impacts your gut microbiome — the vast community of bacteria, fungi, and other microorganisms that live in your digestive tract and influence almost every system in your body.
Lower oestrogen is associated with reduced microbial diversity in the gut, which can trigger a cascade of symptoms many women don't connect to their hormones at all: bloating, constipation, diarrhoea, increased inflammation, and changes in how nutrients are absorbed. It can also affect the gut-brain axis — the direct communication channel between your gut and your brain — contributing to the anxiety, low mood, and brain fog that so many women experience during this transition.
What Probiotics Actually Do
Probiotics are live microorganisms — beneficial bacteria — that help restore and maintain a healthy gut microbiome. They can be found naturally in fermented foods like yoghurt, kefir, sauerkraut, kimchi, and miso, or taken as supplements. Combining both, as I do, gives you the broadest range of strains and the most consistent daily support.
During menopause specifically, probiotics have been shown to:
- Improve digestive symptoms — reducing bloating, irregularity, and gut discomfort caused by hormonal shifts
- Reduce hot flushes — a randomised controlled trial published in the journal Menopause found that women taking a probiotic supplement for 12 weeks experienced a significant reduction in the frequency and severity of hot flushes compared to placebo
- Support mood and reduce anxiety — via the gut-brain axis; a review published in General Psychiatry found that probiotic interventions were associated with significantly reduced symptoms of depression and anxiety. Read more about managing stress and adrenal fatigue →
- Support bone health — declining oestrogen increases the risk of osteoporosis; a meta-analysis published in Osteoporosis International found that probiotics significantly improved bone mineral density, particularly in postmenopausal women. See how Vitamin D also plays a key role →
- Reduce systemic inflammation — a healthier microbiome means lower inflammatory load across the whole body
Food First, Then Supplements
Fermented foods are my starting point because they deliver live bacteria in a highly bioavailable form, alongside the fibre and nutrients that feed them. Sauerkraut, kimchi, live yoghurt, kefir, and miso are all excellent. Aim to include at least one fermented food daily — it doesn't have to be a large amount to make a difference.
Prebiotic foods — those that feed the good bacteria — are equally important. Think garlic, onions, leeks, asparagus, bananas, and oats. A diet rich in plants and fibre is the foundation everything else builds on.
How to Choose a Probiotic Supplement
Not all probiotics are equal. When choosing a supplement, look for:
- High CFU count — CFU (colony-forming units) refers to the number of live bacteria per dose; a higher count means more active bacteria reaching the gut
- Guaranteed live cultures — check that the product guarantees live bacteria at the point of consumption, not just at manufacture
- Clean formulation — no unnecessary fillers, binders, or artificial additives
I've included live bacteria in my Daily Menopause Support because I wanted a formula that addresses menopause from multiple angles — hormonal balance, stress, energy, and gut health together. It's the supplement I wish had existed when I started this journey.
Frequently Asked Questions
What exactly are probiotics?
Probiotics are live bacteria and yeasts that are beneficial to your health, particularly your digestive system. Your gut naturally contains trillions of microorganisms — probiotics help maintain the right balance of good bacteria, which is essential for digestion, immunity, mood, and hormone regulation.
When should I start taking probiotics during menopause?
The earlier the better. Many women begin to notice gut changes in perimenopause — bloating, irregularity, increased sensitivity — before their periods have even stopped. Starting probiotics at this stage can help you get ahead of the disruption rather than playing catch-up. That said, it's never too late to start.
Can I get enough probiotics from food alone?
Fermented foods are a wonderful source of live bacteria and I'd always encourage eating them daily. However, the strains and quantities in food can vary considerably, and it can be difficult to consume enough consistently to make a therapeutic difference — particularly if your microbiome is already depleted. A good quality supplement alongside a fermented-food-rich diet gives you the most reliable, consistent support.
How long before I notice a difference?
Most women notice improvements in digestive comfort within two to four weeks. Benefits for mood, energy, and hot flush frequency tend to build over six to twelve weeks of consistent use. Probiotics work cumulatively — the longer you take them, the more established and diverse your microbiome becomes.
Are there any side effects?
Some women experience mild bloating or changes in bowel habits in the first week or two as the gut adjusts. This is normal and usually settles quickly. If you have a compromised immune system or a serious underlying health condition, speak to your GP before starting a probiotic supplement.
Do probiotics interact with HRT?
There are no known negative interactions between probiotics and HRT. In fact, they work well together — HRT addresses hormonal decline directly, while probiotics support the gut environment that influences how hormones are metabolised and used by the body. Many women find the combination more effective than either approach alone.
Should I take probiotics with or without food?
This depends on the specific product and strains. Some probiotics are best taken on an empty stomach; others are more stable when taken with a meal. Always follow the guidance on your supplement. My Daily Menopause Support is designed to be taken with food as part of your morning routine.
