Introduction
The gut microbiome—made up of trillions of bacteria, fungi, and other microorganisms—is often referred to as the "second brain" of the human body. It plays a vital role in digestion, immune response, metabolism, and even mental wellbeing. For expecting mothers, maintaining a balanced and diverse gut microbiome becomes especially important, as it can influence not only their own health, but also the health and immune system development of their baby.
In this blog, Perdays Australia explores how pregnancy probiotics can support gut health during pregnancy and why they may be an important consideration for mothers-to-be.
Why Gut Health Matters During Pregnancy
During pregnancy, hormonal fluctuations, changes in diet, and heightened nutritional demands can disrupt the natural balance of bacteria in the gut. This imbalance may lead to:
-
Digestive issues such as constipation, gas, and bloating
-
Reduced nutrient absorption, affecting both mother and baby
-
Lowered immunity, making mothers more vulnerable to infections
-
Mood swings and stress, possibly linked to gut-brain axis imbalances
Supporting gut health through probiotics may help restore microbial balance, reduce inflammation, and support optimal digestion and immunity.
Are Probiotics Safe During Pregnancy?
Yes—many probiotics are considered safe during pregnancy and are commonly found in foods like yogurt, kefir, kimchi, and other fermented items. They are also available in supplement form.
According to several clinical studies, specific strains of probiotics may:
-
Help reduce constipation and bloating, common issues in pregnancy
-
Support nutrient absorption, especially calcium, iron, and folate
-
Contribute to stronger immune defense for both mum and baby
-
Improve overall gut-brain axis balance, supporting emotional wellbeing
🧠 Gut-Brain Axis: This bidirectional communication pathway connects the gut and the brain through neural, hormonal, and immune mechanisms. A balanced microbiome may positively influence mental health, stress regulation, and mood during pregnancy.
As with any supplement, it's important to consult a healthcare provider before starting a new probiotic during pregnancy.
Probiotics and Vaginal Microbiota in Pregnancy
Beyond gut health, probiotics may also support vaginal microbiota (VMB)—the community of microorganisms that help maintain vaginal health. A healthy VMB is crucial during pregnancy, as imbalances can increase the risk of infections or complications such as preterm birth.
Factors that influence vaginal flora include:
-
Hormonal fluctuations
-
Immune response
-
Ethnicity and genetics
-
Diet and gut health
Emerging research shows that oral probiotics may help restore healthy vaginal flora, particularly strains of Lactobacillus, which are naturally dominant in the vaginal microbiome. Maintaining this balance can help reduce the risk of bacterial vaginosis (BV), urinary tract infections (UTIs), and other complications during pregnancy.
What to Look for in Pregnancy Probiotics
When choosing a probiotic supplement during pregnancy, look for:
-
Clinically studied strains like Lactobacillus rhamnosus GG, Lactobacillus reuteri, Bifidobacterium lactis
-
Products with clear strain labeling and CFU counts (colony-forming units)
-
Formulations that are free from allergens, artificial additives, and unnecessary fillers
-
Brands that follow good manufacturing practices (GMP) and provide third-party testing
At Perdays, we prioritise high-quality, natural ingredients that are gentle yet effective for mums and safe for baby.
Holistic Gut Health for Expecting Mums
While probiotics can offer targeted gut and vaginal support, overall digestive wellness depends on multiple lifestyle factors, including:
-
A fibre-rich, nutrient-dense diet
-
Adequate hydration
-
Stress management and quality sleep
-
Regular light physical activity (with doctor’s approval)
By combining a healthy lifestyle with the right probiotic support, pregnant mothers can create a strong foundation for their baby’s early development and their own postpartum recovery.
