Cortisol, gut health & menopause: What you need to know

Menopause is a natural transition—but let’s be honest, it doesn’t always feel natural. If you're experiencing fatigue, mood swings, weight gain, brain fog, or sleep issues, you’re not alone. While hormone changes often take the blame, there’s another overlooked culprit: cortisol, your body’s primary stress hormone.

What many women don’t realise is how closely cortisol is connected to gut health. This connection influences everything from your mood to your metabolism—and is the reason why many women are turning to targeted gut-supporting supplements like Better Gut to naturally reduce stress and ease menopause symptoms.

What is cortisol—and why it matters during menopause

Cortisol is produced by your adrenal glands in response to stress. It’s essential for regulating:

• Your sleep–wake cycle
• Blood sugar and metabolism
• Inflammation and immune response
• Fat storage and energy use

However, during menopause, reduced levels of oestrogen and progesterone can make the body more sensitive to cortisol—leading to stronger and longer-lasting stress responses. [1]

How high cortisol levels worsen menopause symptoms

Hot flushes & night Sweats

Cortisol interferes with your hypothalamus, the part of the brain that regulates temperature. This may contribute to the sudden heat surges and night sweats many women experience in menopause. [2]

Insomnia & sleep disruption

At night, cortisol should naturally drop. But under stress, it can remain elevated—making it difficult to fall asleep or leading to 2–3 a.m. wake-ups. Supporting your nervous system with calming nutrients like ashwagandha, magnesium and vitamin B6—as found in Better Night—can help restore your natural sleep cycle. [3]

Mood Swings, anxiety & brain Fog

Elevated cortisol can disrupt neurotransmitters in your brain, making it harder to regulate mood and memory. Ingredients like affron® saffron, ashwagandha, and GABA-supportive B vitamins have been shown to ease stress and support mood stability—making targeted support like Better Night a smart addition to your routine. [4]

Weight Gain, especially around the middle

Cortisol tells your body to store belly fat and triggers cravings for high-sugar, high-fat foods. A healthy gut can help balance these cravings by improving blood sugar regulation and nutrient absorption. [5]

Bloating, food sensitivities & inflammation

Cortisol compromises your gut lining and microbiome diversity, contributing to systemic inflammation. A high-quality probiotic—like Better Gut—can help repair this balance, supporting digestion and reducing inflammatory symptoms. [6]

The gut–cortisol–menopause feedback loop

Stress raises cortisol, which damages the gut, leading to inflammation and worsened hormone symptoms—creating a loop that’s hard to break. But research shows that targeting the gut–hormone–stress axis can reduce symptoms holistically.

Stress → High Cortisol → Gut Imbalance → More Inflammation → More Symptoms → More Stress

This is exactly why many women start by improving their gut health when looking for long-term menopause relief.

The role of gut health during menopause

There’s a profound connection between your gut and your hormones during menopause. Fluctuating hormones disrupt the delicate balance of the gut microbiome leading to a range of symptoms—including bloating, mood swings, brain fog and hot flushes—supporting your gut during this time with a tailored probiotic can help reduce your symptoms as well as helping regulate cortisol, balance oestrogen, and reduce inflammation.

Better Gut is a high-strength probiotic supplement formulated with 50 billion CFUs and six targeted bacterial strains selected to support gut and hormone health during perimenopause and menopause.

Each strain was chosen for its specific benefits in relieving common menopause symptoms:

• Lactobacillus rhamnosus – Can help improve stress resilience, reduce anxiety, and ease bloating, inflammation, and vaginal dryness
• HOWARU® Lactobacillus rhamnosus – A clinically studied strain shown to reduce stress and support emotional wellbeing
• Lactobacillus acidophilus – Helps protect against vaginal and urinary tract infections by maintaining a healthy vaginal microbiome
• Bifidobacterium lactis – May help reduce the severity and frequency of hot flushes and night sweats
• Lactobacillus reuteri – Supports mood balance and sleep quality

This targeted blend works in harmony with your body to help restore balance from within—supporting digestion, stress regulation and hormonal health during every stage of menopause.

Additional lifestyle strategies to naturally lower cortisol

In addition to targeted supplements like Better Gut and Better Night, daily habits play a big role in regulating cortisol levels. Here are simple, sustainable strategies that can help support your stress response:

• Practice daily mindfulness – Just 10 minutes of deep breathing, meditation, or yoga can lower cortisol and improve mental clarity.
• Prioritise gentle movement – Swap intense workouts for walks, Pilates or tai chi. Overtraining can actually raise cortisol.
• Eat regular, balanced meals – Skipping meals or restricting carbs can spike cortisol. Include whole grains, lean protein, and healthy fats at each meal.
• Cut back on caffeine and alcohol – Both can disrupt sleep and elevate cortisol, especially in the evening.
• Get sunlight exposure in the morning – Helps regulate your circadian rhythm and promotes healthy cortisol patterns.
• Set consistent sleep and wake times – A regular sleep routine is one of the most effective ways to support hormone balance and reduce stress reactivity.
• Journal or reflect before bed – Offloading worries in a notebook can quiet your mind and help you sleep more deeply.

These lifestyle changes, when paired with targeted support like Better Gut and Better Night, create a solid foundation for navigating menopause with more energy, better sleep, and fewer stress-driven symptoms.

Menopause doesn’t have to feel out of control

If you’re feeling out of balance, your gut and stress hormones may be to blame. By restoring your gut health and managing cortisol naturally, you can begin to ease symptoms—from sleep issues to mood swings—without relying solely on short-term fixes.

Start by giving your body what it needs to self-regulate.
