The gut connection
Your Gut Is Connected To Everything
Balance starts at the centre and ripples outward. Here’s how the connection works, what it feels like either side of balance, and how we help restore it.

The connection
One centre, four connections
Your gut microbiome is linked to your brain, immune system and skin — not just your digestion — through pathways researchers call axes. So what happens in your gut rarely stays in your gut.
~70%
of our immune cells are found in the gut — so gut balance also supports healthy immune function.

Out of balance vs in balance
How it shows up
Every connection works both ways. Out of balance, you feel it. In balance, everything becomes more predictable.

The ingredients
Seven ingredients across three complementary actions — here’s what each one does, and why it’s in the formula.
01Rebalance · Probiotic
-
Bacillus coagulans Unique IS-2™
Daily dose: 4 billion CFU
Supports microbiome balance, bowel regularity & digestive comfort
Unique IS-2™ is a clinically studied probiotic strain included to help maintain a healthy balance of beneficial gut bacteria. It supports healthy bowel function, stool regularity and digestive comfort, making it the foundation of the formula’s microbiome support.
02Nourish · Prebiotics
-
Propolis
50 mg extract, equivalent to 250 mg propolis
Supports healthy immune function & antioxidant activity
Propolis is a natural substance produced by bees and contains a diverse range of naturally occurring bioactive compounds, including flavonoids and polyphenols. It’s included to complement the formula’s gut-focused ingredients with antioxidant support and help maintain healthy immune system function.
-
Slippery Elm
100 mg inner bark powder
Soothes the digestive tract & supports digestive comfort
Slippery Elm is traditionally used for its soothing effect on the digestive system. Its inner bark is considered a prebiotic fibre and naturally offers a soothing mucilage action when mixed with fluids, helping support a comfortable digestive tract and complementing the formula’s broader digestive support blend.
03Settle · Digestive blend
-
Fennel
45 mg extract, equivalent to 450 mg dry seed
Helps relieve gas & support comfortable digestion
Fennel has a long history of traditional use as a digestive herb. It is included to help relieve flatulence and gas build-up, while supporting digestive comfort and healthy digestive function — particularly when the gut feels full, unsettled or uncomfortable.
-
Ginger
45 mg extract, equivalent to 500 mg dry rhizome
Supports digestion & helps ease digestive discomfort
Ginger is widely used to support healthy digestive function and comfortable digestion. In Gut-Immune Complete, it works alongside fennel and peppermint as part of the digestive blend, helping support the normal digestive process and ease common digestive discomfort.
-
Peppermint
50 mg extract, equivalent to 500 mg dry leaf
Supports a calmer, more comfortable digestive system
Peppermint has traditionally been used to support digestive comfort and help settle an uncomfortable digestive system. Within the formula, it complements ginger and fennel to help relieve digestive discomfort and support a gut that feels more settled after eating.
-
Bromelain
2.88 million PU
Supports digestion through natural enzyme activity
Bromelain is a naturally occurring enzyme derived from pineapple stem. As a proteolytic enzyme, it helps break dietary proteins down into smaller components during digestion. It’s included to complement the herbal digestive blend and provide additional support for digestive processes.

Clinical study reference
Randomised, placebo-controlled study · Individual results vary
“We formulated the Gut-Immune Complete with Bacillus coagulans, specifically the unique IS2 strain — a spore-forming probiotic which demonstrates quite significant resistance against those stomach acids, helping it survive the journey into where it’s meaningful: the small intestine and large intestine.
Once there, it helps to maintain beneficial intestinal flora growth, supports a diverse gut microbiome, balances out healthy bowel regulation, and supports digestive comfort.”

Clinical results at a glance
Evidence Over Empty Promises
Most probiotic research gets stretched into vague microbiome promises. Unique IS-2™ is different: its research measured the things you actually notice — abdominal comfort, stool frequency, stool consistency, gas and bloating.
abdominal comfort
84.9%
of adults achieved improvement, defined as at least a 50% reduction in abdominal pain. [1]
Individual responses may vary.
stool frequency
79.3%
of participants achieved stool frequency within the normal range. [1]
Individual responses may vary.
How it works · gut microbiome
Beneficial Bacteria
By consuming excess oxygen and producing lactic acid in the gut, Bacillus coagulans creates the conditions in which beneficial bacteria like Lactobacillus and Bifidobacterium naturally thrive, supporting a healthy, balanced gut microbiome. [2]
Individual responses may vary.
What the research timeline looks like
-
Week 4
Changes were already being measured
Participants taking Unique IS-2™ showed improvements across measures of digestive symptom severity compared with placebo at the 4-week assessment.
-
Week 6
Stool consistency improved
At six weeks, 65% of participants taking Unique IS-2™ had normal stool consistency, compared with 32.7% taking placebo.
-
Week 8 · End of study
The strongest results were seen at the end
After eight weeks, 79.25% of participants met the study's responder criterion for complete spontaneous bowel movements, compared with 40% in the placebo group.
84.91% also achieved at least a 50% reduction in abdominal pain, compared with 12.73% taking placebo.
Individual responses vary. These results relate specifically to an 8-week randomised, placebo-controlled study of Bacillus coagulans Unique IS-2™ at 2 billion CFU daily in adults with medically diagnosed IBS; they are not a guarantee of individual results.

Good to know
Frequently Asked Questions
Everything you need to know about probiotics, prebiotics and how Gut-Immune Complete works.
What's a prebiotic?
Prebiotics are specific types of dietary fibres and polyphenols that act as food for beneficial gut bacteria. By nourishing these bacteria, prebiotics help support a balanced and diverse gut microbiome.
What's a probiotic?
Probiotics are beneficial bacteria that, when consumed in adequate amounts, help support gut health. They play a role in maintaining microbial balance in the digestive system and supporting normal digestive function.
What's a spore-forming probiotic?
Spore-forming probiotics, such as Bacillus coagulans, have a natural protective outer layer that helps them survive harsh conditions like stomach acid and digestive enzymes. This allows them to reach the gut intact, where they can become active and interact with the existing gut bacteria.
What is IBS? (Irritable Bowel Syndrome)
IBS (Irritable Bowel Syndrome) is a common digestive condition characterised by symptoms such as abdominal discomfort, bloating, changes in bowel habits, and altered stool consistency. Symptoms can vary between individuals and are often influenced by diet, stress, and gut microbiome balance.
Why should I consider Gut-Immune Complete while travelling?
Travel can disrupt digestion due to changes in routine, diet, stress, and time zones. The Gut-Immune Complete combines probiotics, prebiotics, herbal extracts and Bromelains (enzymes) to help support gut balance and digestive comfort during these periods of change, while also supporting immune health.
What are FODMAPs?
FODMAPs are a group of fermentable carbohydrates that can be difficult to digest for some people. In sensitive individuals, they may contribute to symptoms like bloating, gas, and abdominal discomfort. Reducing high-FODMAP foods may help manage digestive symptoms for some people on a short term basis.
Why might a single probiotic strain be chosen instead of multiple strains?
More probiotic strains doesn't always mean better results. What matters most is selecting a strain of bacteria that has been clinically studied, shown to survive digestion, and demonstrated to support gut health. A well-researched single strain can be highly effective by supporting growth of many other beneficial bacteria in the gut rather than simply increasing the number of strains consumed.
