Microbiome Support Australia
If you’d like to look after your gut more deliberately, or you want a clearer picture of what is going on inside it, understanding your options is a good place to start.
Our microbiome support range in Australia includes probiotics in capsule and powder form, alongside stool and breath tests you collect at home. Explore the range to understand the differences and find what suits your needs and routine.
Why your gut microbiome matters
Your gut is home to a large and varied community of microbes, often called the microbiome. It plays a part in how you digest food, how comfortable your gut feels through the day and how your gut and immune system work together. It shifts quietly with diet, routine, travel and medicines such as antibiotics, so it is easy to overlook until your digestion feels unsettled.
Everyday foundations matter most. A varied diet with plenty of different plant foods, such as vegetables, fruit, legumes and wholegrains, gives your gut microbes the fibre they rely on. Regular meals, enough water, daily movement, good sleep and time to slow down while you eat all help your gut settle into a steady rhythm. Any product you choose builds on this base.

When microbiome support makes sense
- You have been prescribed a course of antibiotics, or have just finished one
- You have an overseas trip coming up and want to look after your gut while you are away
- Bloating or bowel discomfort has become a regular part of your day
- You are working with a practitioner who wants more detail about your gut
- Speak with your GP if you notice an ongoing change in bowel habits, blood in your stool, unexplained weight loss or persistent abdominal pain
- Check with a health professional before starting a probiotic if you are pregnant, take regular medication or are choosing one for a child
Gut microbiome testing
Testing suits you if you and your practitioner want information to work from, rather than choosing products by trial and error. Each kit is collected at home and the results are best reviewed with a practitioner.
Choose the GI-Standard Microbiome Profile (GI Map Test) if you want a single stool sample assessed for bacteria, yeasts, parasites, worms and viruses, along with short chain fatty acids and markers of digestion and gut barrier function. The Doctor’s Data GI 360 Test Australia is a stool analysis performed by Doctor’s Data in the USA, while the Lactulose SIBO Breath Test measures hydrogen and methane in timed breath samples, with express return postage to the laboratory included.
Antibiotics and travel
These products are often considered around a course of antibiotics, when you want to look after your gut flora, and some also ahead of travel. Each contains Saccharomyces cerevisiae (boulardii), and they are a targeted choice for these specific times.
Choose Yomogi Saccharomyces cerevisiae (boulardii) Probiotic if you’d like a single-strain capsule (250 mg per capsule) that supports good gut flora during and after antibiotics and helps reduce the occurrence of traveller’s diarrhoea symptoms. Metagenics Ultra Flora SB Diarrhoea Support Probiotic (60 Caps) pairs boulardii with Bifidobacterium lactis in a vegetable capsule for the same situations, while SFI Health Antibiotic BioRenew combines boulardii with Bifidobacterium animalis ssp. lactis BB-12 in a 15-capsule pack, used to support and restore good gut flora during and after antibiotic use.
Bloating and bowel comfort
This section suits you if bloating is the main thing you notice day to day. These are multi-strain formulas, and the main differences are form and the number of strains.
Choose Bioceuticals UltraBiotic 500 if you prefer a powder: each sachet provides 14 strains at 500 billion CFU and is used to relieve bloating and bowel discomfort and support bowel regularity. SFI Health Ther-Biotic BioDaily is a capsule combining boulardii with Lactobacillus and Bifidobacterium strains to relieve bloating and bowel discomfort, and Bioceuticals Ultrabiotic 60 is a nine-species capsule that helps relieve bloating and assists the digestion of lactose.
Everyday gut flora
These options suit you if you’d like ongoing support for healthy gut flora, including at particular stages of life or through the seasons. Several are a single strain, chosen deliberately for a specific use.
Choose Metagenics Gut Ultraflora Immune Control if you want a capsule with Lactobacillus rhamnosus (LGG) and Lactobacillus paracasei (LP-33) that helps relieve symptoms of hayfever and seasonal allergies. Metagenics Mother and Baby Probiotic is used to support a healthy pregnancy and maintain gut flora in breastfeeding and post-partum women, and Spectrumceuticals L Reuteri is a single-strain powder (5 billion CFU per gram) that supports intestinal health and good gut flora.
Common questions about microbiome support
Can I take a probiotic while I’m on antibiotics?
Many people do, and it is common to take the probiotic a few hours apart from each antibiotic dose. Follow the directions on the label, and check with your doctor or pharmacist about timing, particularly if you take other medicines as well.
What should I look for on a probiotic label?
Look for the full strain name, which is the code of letters or numbers after the species, such as LGG or 299v. Probiotics are chosen by strain, so this tells you more than the species alone. Also check the amount per serve (CFU), the form, and the storage directions.
Do probiotics need to be kept in the fridge?
Some do and some are shelf stable, so check the storage directions on each product. If a product needs refrigeration, put it in the fridge as soon as it arrives, and consider express post in warmer months so it spends less time in transit.
