Best Probiotics Australia

Probiotics are friendly microbes that live in the gut. They aid digestion and help keep the gut healthy.

In addition to probiotic bacteria, the gut also contains many other microbiota including fungi and viruses. Some of these are friendly, while others have the potential to cause disease. Probiotics help keep these under control.

1.    YourBiology Gut (editors choice, click for details)
2.    Biotics8
3.    1MD Complete Platinum

Collectively, this microbial colony is known as the gut microbiome and it influences many aspects of health. The gut microbiome is so important that scientists consider it a virtual organ. [1]

When probiotic supplements first became popular, the people using them were primarily interested in improving their gut health. However, an ever-growing body of research shows good probiotic supplements can also improve many other aspects of health such as immune function.


There are even probiotics that can help control the symptoms of menopause, assist weight loss, and may even provide healthier-looking skin.

Not surprisingly, probiotics are becoming increasingly popular all over the world, including Australia. In 2019, the Australian probiotics market was estimated to be valued at US$317.395 million and projections suggest it will continue to grow. [2]

Unfortunately, with so many options to choose from, it can be difficult to find the best probiotic supplements to use.

This article provides information about the most effective probiotic supplements available to Australians in 2023.

#1. YourBiology Gut+


YourBiology Gut+ is a high-quality probiotic supplement that provides strains from four of the most versatile species of probiotic bacteria. Three of them come from the Lactobacillus bacteria family. The other belongs to the Bifidobacterium family of bacteria.

Although four species may not sound like a lot, collectively, they deliver 40 billion culture-forming units (CFU). That's a generous helping of good bacteria that's capable of enhancing your gut microbiome and changing things for the better.

YourBiology is arguably the best probiotic for bloating on the market and a big seller worldwide.

Probiotics are very versatile. Each species can provide multiple health benefits.


For instance, research shows Lactobacillus acidophilus (L. acidophilus) bacteria strains that can enhance the immune response to viruses and help relieve the symptoms of menopause. [3, 4]

L. acidophilus is also one of the best probiotics for supporting weight loss. Research suggests this may be because it activates brown adipose tissue (BAT). [5]

The benefits we have mentioned here barely scratch the surface. L. acidophilus offers multiple additional benefits and the other four probiotics in YourBiology Gut+ are equally good.

In addition to providing four of the best probiotic species, YourBiology Gut+ provides some prebiotic fibre to help keep the bacteria alive and nourish the existing probiotics already in the gut.


The capsules also have a special coating. It's a seaweed derivative called Maktrek.

Maktrek shields the capsules from the digestive enzymes in the stomach by delaying their disintegration until they reach the gut.

If the capsules were to disintegrate inside the stomach, some of the probiotics could be killed. So instead of letting its probiotic passengers exit early, Maktrek transports them to exactly where they need to be.

YourBiology Gut+ Pros 

●    Provides 4 of the best strains of good bacteria
●    High potency (40 Billion CFU)
●    Contains prebiotic fibre for healthy gut flora
●    Uses Maktrek delivery technology
●    Has multiple health benefits
●    Does not require refrigeration
●    The manufacturer provides free shipping to Australia
●    Opportunities to get free bottles by placing larger orders
●    Backed by a 60-Day Money-Back Guarantee


YourBiology Gut+ Cons

●    Only available from the official website
●    There may be limits to the number of bottles available per household during times of high demand

#2. Biotics 8 (Best Probiotics for Male Digestive Health)


Biotics 8 is a highly effective probiotic supplement that's become a big hit with men all over Australia. Its level of popularity is not surprising because Biotics 8 is specifically formulated for men.

With a CFU of 20 Billion, Biotics 8 has a lesser overall potency than YourBiology Gut+ but 20 Billion is still a generous serving. There are plenty of alternative options that contain considerably less.


With 10 probiotic species per dose, Biotics 8 offers a diverse range of benefits and, like YourBiology Gut+, it also provides prebiotic fibre. All the most effective probiotic supplements do.

Although all the probiotics in Biotics 8 have benefits that will be attractive to women as well as men, this combination has been chosen with men in mind.

For instance, research suggests Lactobacillus plantarum (L. plantarum) and Lactobacillus paracasei (L. paracasei) are two of the best probiotics for improving sperm quality and motility. [6, 7]

In addition to providing some of the best probiotics for men and prebiotic fibre, Biotics 8 has some vitamin D for immune health benefits.


According to the Australian Bureau of Statistics, 23% of Australian adults do not get enough vitamin D. [8]

Although this is an issue that appears to affect as many women as men, lack of vitamin D may hit men extra hard because vitamin D plays a key role in testosterone production.

Some research suggests a link between vitamin D deficiency and prostate cancer. It's the most commonly diagnosed cancer in Australia and estimates suggest one in six men will be diagnosed with it before they reach their 85th birthday. [9, 10]

Biotics 8 Pros 

●    Specially formulated for men
●    Provides 10 strains of probiotic bacteria
●    20 Billion CFU
●    Contains prebiotic fiber
●    No refrigeration is necessary
●    Delivers multiple health benefits
●    Supports testosterone production and good prostate health
●    The manufacturer provides free shipping to Australia
●    Opportunities to get free bottles by placing larger orders
●    Has a 60-Day Money-Back Guarantee


Biotics 8 Cons

●    Only available from the manufacturer's website
●    Not an ideal probiotic formula for women

#3. 1MD Probiotic Platinum


Popular in Australia and all over the world, 1MD Complete Probiotics Platinum is one of the best probiotics for people who want a supplement that covers all of the bases.

Although this gut health supplement is mainly marketed for digestion health and enhanced immunity, with 11 strains of probiotic bacteria and a good helping of prebiotic fibre, it can do a lot more.

For instance, in addition to being useful for providing relief from the symptoms of irritable bowel syndrome (IBS), strains from the Lactobacillus rhamnosus (L. rhamnosus) species of probiotic bacteria also appear to support good prostate health. [11, 12]


1MD Complete Probiotics Platinum also provides L. acidophilus. Two of the many benefits this probiotic offers are a better immune response against viruses and relief from the symptoms of menopause. [3, 4]

YourBiologyGut+ provides L. acidophilus too and the CFU is 4 times higher. However, although 1MD Complete Probiotics Platinum provides this species in lesser amounts, the formulation has additional probiotics that can fight these same two corners.

Like YourBiology Gut+, 1MD Complete Probiotics Platinum uses a special coating that delays capsule disintegration and helps ensure the probiotics are released into the gut instead of the stomach.

Some of the benefits this probiotic supplement provides, such as improved digestion, may be noticeable within hours of taking the first dose. However, others such as increased vitality, may take a few months to kick in. The key to getting the best from a supplement like this is to use it with consistency.


1MD Complete Probiotics Platinum Pros

●    Contains 11 of the best probiotics and beneficial bacteria
●    High potency (51 Billion CFU)
●    Provides prebiotic fibre for healthy bowel flora
●    Uses a special coating that delays capsule disintegration
●    Shelf-stable and does not require refrigeration
●    Discounts are available when you buy 3 or more bottles or commit to auto-ship
●    The manufacturer provides a 90-Day Money-Back Guarantee

1MD Complete Probiotics Platinum Cons

●    Only available via the manufacturer's website
●    Ships from the USA
●    No free shipping options to Australia

Benefits of Using Probiotic Supplements (Health Claims)

The best probiotics support good health in many ways. Each strain can provide so many benefits it would be impossible to compile a list of all the things the top options can do.


However, let's take a look at a few.

Better Gut Health - Balanced Intestinal Flora and Healthy Gut

Improving gut health and gut bacteria was the main reason people used to take this type of supplement. Even though we now know probiotics offer benefits that exceed the reach of the gut, better gut health remains a primary focus for many people who use this type of supplement.

Some of the gut-related issues probiotics can help with include constipation, antibiotic-induced diarrhea, leaky gut syndrome, bloating, and intestinal gas.

Enhance Immune Function and Immune System Health

When you improve the state of your gut bacteria by using any of the best probiotics, you should notice improvements in immunity. Certain strains, such as L. acidophilus, can be very helpful in this regard.


Improved Mental Health

Taking probiotics appears to improve mental health and ability. Common benefits include relief from anxiety and help with depression.

However, as with any over-the-counter (OTC) dietary supplement, some people may get a better response than others.

If you have mental health issues, it would be unwise to try and use probiotic supplements as a primary treatment. However, you may find that they may work well alongside your existing medication.

Regularly consuming probiotics has been shown to significantly reduce anxiety and depression in some people.

Relief from High Cholesterol, Weight Gain and Weight Management

Some studies suggest Lactobacillus bacteria can help reduce low-density lipoprotein (that's the bad type).


Cardiovascular Improvements

In addition to helping lower cholesterol, probiotics can also reduce blood pressure. When blood pressure reduces, it reduces strain on the heart and blood vessels.

Improvements in Bone Mineral Density

Some probiotic strains appear to support improvements in bone mineral density. This can make probiotics a good option for menopausal and postmenopausal women hoping to avoid osteoporosis and for men struggling with low testosterone (which can also weaken bones).

Probiotic Dietary Supplements Side Effects and Suitability Issues

Although a probiotic supplement benefits most people, if you have an existing medical condition it may be a good move to get your doctor's approval before using a digestive health or a supplement to improve the digestive system.


Some people may not be able to use probiotics at all. People who have HIV or AIDS are a couple of obvious examples because both conditions impair immunity.

However, certain medical treatments can weaken immunity too, such as chemotherapy and radiation treatment.

If you have any doubts about using probiotics, the best thing to do is book an appointment with your doctor and get some expert advice.

Although side effects are rare, a minority of people experience issues when they first begin using daily probiotic digestive health supplements

The most common side effects are intestinal problems such as bloating, gas, and changes in bowel movement.


However, issues like these generally resolve themselves quite quickly after the body adjusts to the new state of play in the gut microbiome.

Best Probiotics Australia - How to Choose

When you are looking for the best probiotics in Australia, it's best to begin by taking a look at customer reviews. When supplements work well for other people the chances are high they will work for you too.

The ingredient profile is also important. Good probiotic supplements need to be at least 20 Billion CFU (colony forming units). If they don't they will probably provide poor results.

It's also best to choose shelf-stable options that do not require refrigeration. Especially in a warm country like Australia.


Non-shelf-stable probiotic supplements need to be kept constantly cool. If they are not, the bacteria inside them die.

The problem with options such as these is, although you may be careful to make sure your probiotics keep their cool, you can never be sure of the temperatures they have been exposed to during storage or transit.

All three of the probiotic supplements we recommend are shelf stable. 

All the best probiotic supplements also have money-back guarantees. If you ever see a probiotic that doesn't, ask yourself why not? The answer to that question probably won't need much thinking about.

Get the Maximum Value for Money When Buying Probiotics in Australia


Although this is not the case with many other dietary supplements, all the best probiotic gut health products are distributed by manufacturers that offer discounts or extra products, to customers who place larger orders.

There's a lot to be said for taking advantage of deals like these. Opportunities such as getting three bottles of pills for the price of two or five bottles for the price of three can result in big savings.

The manufacturers of YourBiology Gut+ and Biotics 8 always offer customers these options. This may be one of the reasons both supplements are such hot sellers but, of course, the quality of the supplements is their biggest selling point.


Probiotics are supplements you use long-term. Once people find a probiotic they like, they often stick with it for life.

Best Probiotics Australia FAQs

What is CFU?

CFU stands for culture-forming units. It lets you know how many live probiotic bacteria you will get from each dose.

All the best probiotic supplements provide at least 20 Billion CFU per dose.

What is the benefit of multi-strains probiotics?

The human gut microbiome is home to thousands of different bacteria strains. Some of them, such as L. acidophilus are good, others are pathogenic.

Each probiotic bacteria strain has unique properties and health benefits. When you take a good multi-strain supplement, you reap the benefits associated with all the probiotics that are present.


The best probiotic supplement provides four or more bacteria strains. By doing so, they deliver a wide spectrum of benefits to restore healthy bowel flora.

What is a prebiotic?

Prebiotics are supplements that provide prebiotic fibre. The human digestive organs cannot process this type of fibre so it reaches the intestines in its raw state.

Although prebiotic fibre offers no nutritional value to us humans, for probiotic bacteria it's food. So, when you consume prebiotic fibre, it helps the probiotic bacteria inside your gut to thrive and multiply.

Fortunately, prebiotic fibre has no value at all to gut pathogens.

All the best probiotics provide prebiotic fibre.


Should I keep my probiotics in the fridge in Australia?

It is recommended to keep all supplements in a cool place regardless of where you live. If you live in Australia the fridge is a good place to store supplements, particularly probiotics.
