What is the vaginal microbiome?

The community of microorganisms that live inside the vagina — working together to protect your intimate health every single day.

pH 3.5–4.5

💧

A healthy microbiome is dominated by lactobacilli — beneficial bacteria that produce lactic acid, keeping your vaginal environment slightly acidic. This acidity is your first line of defence.

When lactobacilli are thriving, they prevent harmful bacteria and yeast from gaining a foothold. They support healthy discharge, control odour naturally, and maintain a self-cleaning environment.

Think of it as an ecosystem. When the ecosystem is in balance, everything works. When it tips — even slightly — symptoms can follow.

Why balance matters

A balanced vaginal microbiome isn't just about comfort — it affects your everyday wellbeing, reproductive health, and long-term protection from infections.

🛡️
Infection Protection
Balanced bacteria dramatically reduce your risk of BV, thrush, and recurring irritation. Lactobacilli create an environment where pathogens simply can't thrive.
🌿
Natural Self-Cleaning
A healthy microbiome keeps discharge within normal ranges — your body handles cleansing naturally. No soaps, no douching needed inside.
🌸
Odour Control
Healthy flora prevents strong or unusual odours. If you notice a persistent smell, it's your microbiome signalling an imbalance — not a hygiene failure.

Section 03

When the microbiome becomes disrupted

Dysbiosis — an imbalance of good and bad bacteria — can happen to anyone. Tap a symptom to understand what it might mean.

Common causes

Antibiotics kill both bad and good bacteria. After a course, your lactobacilli population can drop significantly, leaving you vulnerable to BV or thrush. Always take a vaginal probiotic during and after antibiotics.

Oestrogen plays a key role in maintaining lactobacilli populations. Hormonal contraception, perimenopause, menopause, pregnancy, and even your menstrual cycle can all temporarily shift your pH and microbiome composition.

Scented soaps, feminine washes, douching, scented pads and tampons — all can disturb your vaginal flora. The vagina is self-cleaning; products used inside it tend to do more harm than good.

Semen is alkaline (pH ~7.2), which temporarily raises vaginal pH. High stress, poor sleep, excess sugar, tight synthetic underwear, and sweating without airflow all affect microbiome stability over time.

How to support your microbiome

Small, consistent habits make the biggest difference. Tick off the ones you already do — then work on the rest.

Hygiene habits

  • ✓Use a gentle, pH-balanced feminine wash (vulva only — never inside)
  • ✓Avoid douching entirely
  • ✓Skip fragranced soaps, sprays and wipes
  • ✓Rinse with warm water after exercise or swimming
  • ✓Avoid scented pads and tampons
  • ✓Wipe front to back always

Lifestyle & clothing

  • ✓Choose cotton or bamboo underwear daily
  • ✓Avoid sitting in damp or wet clothing
  • ✓Sleep without underwear to improve airflow
  • ✓Avoid tight synthetic fabrics long-term
  • ✓Use condoms to maintain pH after sex
  • ✓Take a vaginal probiotic after antibiotics

Section 05

Diet & lifestyle that helps

What you eat directly influences your vaginal flora. Hover over each food to learn why it helps.

🥛
Yoghurt
Live cultures replenish lactobacilli. Look for "live active cultures" on the label.
🥤
Kefir
A more potent probiotic than yoghurt — packed with diverse beneficial bacteria strains.
🥬
Sauerkraut
Fermented cabbage is rich in lactobacilli and supports overall gut-vaginal microbiome connection.
🌶️
Kimchi
Fermented and anti-inflammatory. Gut health directly impacts vaginal flora diversity.
🧄
Garlic
Natural antifungal properties that can help balance yeast levels in the body.
🌾
Oats
Prebiotic fibre feeds good bacteria, supporting both gut and vaginal microbiome health.
🫐
Berries
Antioxidant-rich and low in sugar — berries support immunity without feeding Candida yeast.
🥦
Leafy greens
Rich in folate and vitamins that support hormonal balance and healthy microbiome diversity.

Things to reduce

🍬 Refined sugar — feeds Candida 🍺 Excess alcohol — disrupts gut flora 🍟 Ultra-processed foods — inflame the gut ☕ Excessive caffeine — affects hormone balance

Section 06

When to see a doctor

Self-care goes a long way, but some situations need professional attention. Don't wait if any of these apply to you.

⚠️
Seek care if you have...
Symptoms that are severe or keep returning · Pelvic pain or fever · Unusual bleeding · More than 3 infections in a year · Pregnancy with symptoms · Symptoms that don't improve with home care
🔬
Always get a diagnosis first
BV and thrush have different treatments. Using an antifungal for BV (or vice versa) won't work and may make things worse. A swab from your GP or sexual health clinic gives a clear answer quickly.
✅
Safe to manage at home when...
Symptoms are mild and infrequent · You have a confirmed prior diagnosis of thrush · You've been cleared by a GP recently · You're supporting balance proactively, not treating an active infection
💊
Supportive products that help
Vaginal probiotics with Lactobacillus rhamnosus & reuteri · Calendula suppositories for pH support · pH-balanced intimate wash · Boric acid suppositories (post-GP advice for recurrent BV)
