Product overview

SporeBiotic™ is a revolutionary unique and highly effective probiotic designed for everyone. This microbiologist formulated, 100% spore-based, broad-spectrum probiotic formula helps reconditions the gut by supporting an increase in microbial diversity and encouraging the growth of key gut bacteria and antioxidants to support a healthy microbiome. If you have gut challenges or haven’t responded to other probiotic formulas, take control of your health and feel the Gutsi® difference. 

Bacillus spores

SporeBiotic™ is made with Bacillus spores. These spores have been found naturally in the environment for millions of years developing a symbiotic relationship with their human host. They are found in soil, rocks, dust, vegetation and water, as well as in the digestive systems of insects, marine life and mammals. They live in the gut and use the soil to aid transfer from host to host. As a true commensal organism, Bacillus spores very effectively colonise the gastrointestinal tract of both humans and animals. 

  • Bacillus spores have a bi-phasic life cycle. Depending on their environment, they can change form from dormant to active. When dormant, Bacillus surrounds itself with an endospore, a naturally robust outer shell that protects it from light, pressure, heat, acid, oxygen and other environmental factors. Once Bacillus spores reach the gut, they can sense that conditions are suitable for survival and resume their active form.
  • Bacillus spores were abundant in our ancestor’s food supply. However, modern food systems have sterilised food processing, and foods and animals are treated with antimicrobial agents which has eliminated our exposure to these essential bacterial organisms.
  • When in hibernation, Bacillus spores are highly stable and can survive in conditions ranging from 200°C to -60°C. Their ideal growth temperature is 37°C, the internal temperature of the human body.
What makes SporeBiotic™ different from other probiotics?

SporeBiotic™ contains four Bacillus strains: Bacillus indicus HU36™, Bacillus clausii (SC-109), Bacillus subtilis HU58™, and Bacillus coagulans (SC-208) that have been shocked back into their spore form. This unique feature allows SporeBiotic™ to naturally survive the harsh environment of the digestive system. 

Research shows these specific strains support intestinal permeability and found to have a 100x better survival rate than leading probiotics or yoghurt. In addition to supporting a healthy bacterial balance, these strains have many other properties and benefits, some of which are listed below: 

  • Resistant to antibiotic therapy
  • Increases the body’s natural production of carotenoids (antioxidants)
  • Produces nutrients including vitamin K and all the B vitamins
  • Supports the body’s production of up to 12 natural antimicrobials
  • Produces the enzyme nattokinase
  • Neutralises toxins
  • Competes with, and crowds out pathogens
  • Supports an increase in butyrate production
  • Supports the lymphoid tissue in the gut, an important part of the immune system
  • Produces L+ lactic acid, not D-lactate
  • 99.99% survivability through the digestive tract
Explore our spores!

Bacillus indicus HU36™ 

B.indicus produces high levels of powerful carotenoids (antioxidants) at the site of absorption. Carotenoids do not survive the gastric system well. B.indicus however, has demonstrated the ability to survive past the stomach acid and produce the carotenoids at their site of absorption in the gut. This makes the carotenoids produced by B.indicus the most bioavailable supplementary carotenoids in the marketplace. B.indicus gives SporeBiotic™ a function that no other probiotic formulations on the market can claim – it provides key nutrients in their most potent form. 

Bacillus clausii (SC-109) 

This strain is the largest selling strain of probiotics in the world. B.clausii is recommended as an adjunct to antibiotic treatment due to its ability to resist damage from a variety of common antibiotics. 

Bacillus subtilis HU58™ 

Extensively studied on genetic and functional levels, B.subtilis has a unique ability to produce nearly 12 strong natural antimicrobials. B.subtilis produces the enzyme nattokinase and has been shown to support healthy blood pressure, cholesterol management and normal clotting by fibrinolysis. B.subtilis also produces a number of other nutrients that have systemic health benefits such as B vitamins and Vitamin K2. B.subtilis is an extremely potent immune supporter. It germinates in the small intestine and provides broad-spectrum immune support. 

Bacillus coagulans (SC-208) 

Identified in the 1930s, B.coagulans is a well-studied probiotic that supports healthy bowel function and offers potent immune supporting activity. B.coagulans produces the L+ optical isomer of lactic acid, which has been shown to have a more profound effect on immune support and gut defence than the other forms of lactic acid produced by conventional probiotics. It is a great coloniser and plays a key role in the digestion of food and absorption of nutrients. B.coagulans can digest incoming fat to reduce the uptake of cholesterol. This powerful strain adds another dimension to SporeBiotic™, giving it a potent ability to support healthy bowel function, aid in digestion and crowd out unwanted pathogens. 

The missing link

Did you know that spore-based probiotics are much more effective than conventional probiotics on the market? Why? Because they are designed to survive through the harsh gastric system, colonise and support an increase in microbial diversity in the gut. In addition, the spores are so multi-functional that they maintain their efficacy for a broad spectrum of conditions! 

Gutsi® SporeBiotic™ is a unique, multi-spore probiotic available as a dietary supplement. A culmination of published research shows that the spores found in SporeBiotic™ can support healthy mood, heart, skin, as well as gut function and healthy digestion by supporting butyrate production and healthy weight management by supporting metabolic function. 

How SporeBiotic™ fits into the Gut Reset protocol

SporeBiotic™ is introduced in week 1 of the 60-day Gut Reset protocol. SporeBiotic™ is foundational to reseeding and balancing the gut as well as supporting microbial diversity and commensal, keystone gut bacteria for a happy, healthy microbiome.

Suggested Use

Recommended intake:

Ages 4+: Take 1 capsule daily or as directed. Best taken with meals, capsules may be opened and mixed with food or drink. If symptoms persist and for children under 4 years, consult your healthcare practitioner.


Take with food: The amino acids and carbohydrates in food help change the dormant spores into their active, vegetative state in the GI tract. Capsule contents may be added to food or beverage if preferred.

Start slow: To give your body time to acclimate to SporeBiotic’s potency, we recommend you titrate the dose up slowly. In week 1, take 1 capsule every other day. In week 2, increase to 1 capsule per day.

If you are sensitive or experience any detoxification symptoms*, please contact our friendly naturopaths who can help you with a more personalised approach.

No refrigeration required: SporeBiotic™ is completely resilient and shelf stable.

*Detoxification symptoms may present as bloating, loose stools, changes in bowel habits, and/or digestive discomfort. If these issues arise, it is recommended that you reduce the dosage to prevent this from occurring. You may reduce to ½ capsule every 2nd day and continue until all symptoms have subsided.

  • If pregnant, nursing or taking medications, consult a healthcare practitioner prior to use.
  • Keep closed in dry place; avoid excessive heat.
  • Do not use if safety seal is broken or missing.
  • Keep out of reach of children.
  • Always read the label and use as directed. If symptoms persist see your healthcare practitioner.

    I have been using Gutsi for 3-4mths it’s made such a difference to me after 4yrs of chronic digestive and bowel issues, heartburn is almost a thing of the past now. It’s great to be out walking again. Definitely would recommend.

    This is the one product that I NEED to take every day. If I miss even one day, I immediately notice that my tummy is not quite right. Highly recommend!

  4. Claire

    I have tried many probiotics, but none of them have worked for me. This one on the other hand, actually does what it says!

  5. Emma

    my whole family is on this product and our digestive health has never been better! even when we have a cheat meal, somehow my tummy stays feeling great the next day

  6. Eileen

    Fantastic! My stomach has been so calm even after a curry so will continue taking it.

  7. Anita

    I have put off giving a review until I was really sure of results. I cant remember how long I have been taking Gutsi, but Im pretty convinced now that my digestive system is 100% better than when I started taking it . Sometimes it’s easy to forget how bad something was. I take one every morning, because I genuinely feel that it makes a difference and have recommended Gutsi to my family and anyone who will listen.”
