Naturopath formulated
Multi+ Probiotic contains four well-researched probiotic strains — Lactobacillus paracasei LPC-37, Lactobacillus plantarum 299V, Lactobacillus rhamnosus SP1, and Lactobacillus rhamnosus GG — delivering 32.5 billion CFU per capsule.
Each strain has been selected for a specific role. Together, they work to restore balance in your gut microbiome, strengthen the gut lining, and reduce inflammation from within.
This matters because your gut doesn't work in isolation, it's in constant communication with your skin, brain, hormones, and immune system through a network of biological pathways.
When your gut is supported, the effects are felt across your whole body. You may notice easier, more comfortable digestion, calmer and clearer skin, a more stable mood, better resilience to stress, and a stronger immune response.
Multi+ Probiotic doesn't just address surface-level symptoms. It targets the root systems that influence how you look, feel, and function every day.

FAQ
Multi+ Probiotic was designed to do more than just support your gut. Each of its four clinically studied strains targets a specific system — gut, skin, mood, and immune — so you feel good from the inside out.
Unlike many probiotics that overload on strains or filler bacteria, Multi+ uses only research-backed doses that work synergistically. Every capsule is formulated with precision, purity, and integrity — no fluff, no marketing gimmicks, just results.
Yes. Multi+ Probiotic is formulated to support healthy digestion, bowel regularity, and overall gut comfort. It helps balance your microbiome, reduce bloating and ease common IBS-type symptoms like flatulence, abdominal pain, and constipation - all while supporting the gut lining itself.
Yes, the strains in Multi+ have been researched in adults, including pregnant women. Because each pregnancy is different, we always suggest chatting with your healthcare practitioner before starting anything new.
They can and it’s one of the most exciting areas of research. The gut-skin connection means that when your digestive system and microbiome are in balance, your skin reflects it. Multi+ Probiotic contains specific strains shown to soothe skin inflammation and support clearer, calmer skin from within.
Everyone’s microbiome is unique, but most people start noticing changes in 2–4 weeks - think easier digestion, less bloating, and steadier energy. Skin, mood, and immune benefits tend to show within 6–8 weeks of consistent use. Multi+ works best as part of your daily routine - one capsule a day, every day.
No refrigeration needed. Multi+ is sealed in protective Alu-Alu blister packs, which protect the live probiotic strains from heat, moisture, and oxygen - keeping them stable and potent until the very last capsule.
Yes. Multi+ is made in a TGA-licensed facility in Australia under strict quality and safety standards. Each batch is third-party tested to confirm purity, potency, and shelf-life stability. What’s on the label is exactly what’s in the capsule
Multi+ Probiotic is a TGA-listed product, which means every single ingredient, including functional excipients, is fully declared and must meet strict safety, quality, and purity standards.
Alongside our four clinically studied probiotic strains, Multi+ contains a small number of pharmaceutical-grade excipients. These help protect the live cultures, ensure stability and form the vegan capsule. They are not artificial preservatives and are included only in functional amounts.
Excipients in Multi+ Probiotic:
- Calcium hydrogen phosphate dihydrate — supports product stability and flow
- Colloidal anhydrous silica — prevents clumping and protects the probiotic blend
- Hypromellose — vegan capsule shell
- Magnesium stearate — ensures consistent capsule fill and quality
- Maize starch — natural flow aid
- Maltodextrin — used in tiny amounts as a carrier to protect the freeze-dried probiotic strains and improve stability (not used as a sweetener or filler)
- Microcrystalline cellulose — plant-based stabiliser
- Purified potable water — used in the capsule formation process
Are any of these artificial preservatives?
No. Multi+ contains no artificial preservatives, no artificial colours or flavours, and no unnecessary fillers. These excipients simply ensure the probiotic strains remain alive, stable, and effective from manufacturing to ingestion.
Why is maltodextrin used?
Maltodextrin is included only in tiny, functional amounts as a carrier during the freeze-drying process. It encapsulates and protects the probiotic bacteria from moisture, heat, and oxygen, helping them survive manufacturing and storage, without the need for preservatives. The amount used is extremely small and not physiologically active.
Definitely. Multi+ is designed for ongoing use to help you maintain a healthy microbiome and feel your best long-term. Consistency is key — daily use keeps your gut flora balanced, your skin clear, and your immune and mood systems supported.
Anytime that works for you — morning tends to be easiest. Take one capsule daily with water, ideally around the same time each day to build the habit and support consistent results.
Yes. Multi+ is vegan-friendly, gluten-free, dairy-free, soy-free, and contains no artificial colours, flavours, or preservatives. It’s formulated with clean, evidence-based ingredients — nothing unnecessary, just what your body needs to thrive.
In most cases, yes. Multi+ is safe to take alongside other supplements and medications. If you’re taking prescription medication, or have specific health concerns, it’s best to check with your healthcare practitioner for individual advice.

When to expect results
Every microbiome is unique, but consistency is key. Multi+ is designed to create meaningful, long-term shifts—not overnight fixes. Here’s what you can expect:
Week 1 - 2
What you may notice: Less bloating, smoother digestion, more regular bowel movements
Week 3 - 4
As your microbiome begins to rebalance, many notice: clearer skin, steadier energy, and a more stable mood. Internal inflammation starts to ease as beneficial bacteria strengthen the gut barrier.
Month 2 - 3
Your gut ecosystem becomes more resilient. You may experience: improved stress tolerance, a stronger immune response, and visible skin calmness. These shifts signal that the deeper systems - gut, skin, mood, and immune - are working in sync.
Ongoing
With daily use, Multi+ continues to reinforce the gut–brain–skin axis, helping you maintain the results you’ve built and supporting long-term wellbeing from the inside out.

Convenience and simplicity is really important for many of my clients, plus the peace of mind that a product is actually going to have the effects that it claims! Multi+ is a targeted formula I would recommend to many of my clients to support their overall microbiome health. Having a probiotic that is shelf stable and doesn’t need refrigeration is my preference every time! It means that you don’t have to worry if you’re travelling about storage and it’s easier to stay on track. I would recommend this probiotic as an all rounder to my clients struggling with complaints like bloating, sluggish digestion, congested skin or recurrent infections. Treating the gut microbiome with targeted probiotics is such a great way to optimise health from a multi-system approach.

Its targeted formulation offers comprehensive support for people experiencing IBS symptoms, immune dysregulation, skin inflammation, and stress-related gut issues.This kind of broad-spectrum support is ideal, as we rarely see these conditions in isolation.

SolBiome's Multi+ Probiotic is a well-rounded probiotic with broad clinical applications. With so many strains of probiotics on the market, it's important to me to choose products with carefully curated strains that I know will work for my patients. The combination of probiotic strains chosen is completely unique to this product and I have struggled to find one product which effectively supports the immune system, skin inflammation and mood imbalances. Being a naturopath formulated product, I know that I can trust the amount of research that has gone into this formula and the understanding of strain-specificity. I can't wait to use this in clinic!

The Multi+ Probiotic is a true game changer for microbiome driven imbalances and disease. Its unique blend of strain specific probiotics not only targets the gut, but also supports interconnected systems throughout the body. What stands out most is how effectively it addresses the complex relationships between conditions that are often treated in isolation.
As a practitioner, it’s invaluable to have one product that is both research backed and versatile enough to be used across a wide range of presentations. The Multi+ Probiotic makes prescribing simpler, while providing patients with a comprehensive, evidence based tool for optimising health and working on multiple microbiomes, not just the gut.

What sets this apart for me is the combination of Lactobacillus rhamnosus GG for general gut support and Lactobacillus rhamnosus SP1 for targeted skin health—a powerful combo that I have not seen in one product before. With the addition of stress-supportive strains, this probiotic is incredibly well-rounded and highly targeted.

It's so refreshing to see this strain-specific and targeted probiotic hitting the market. Gone are the days of broad-strain probiotic products containing a stack of random 'health-promoting' microbes that just don't live up to their claims. We are in real need of evidence-based probiotic formulations showcasing rigorously studied strains at therapeutic dosages that actually work for our clients. I'm really excited to see the introduction of SolBiome Multi+, and can't wait to trial it in my clinic.

The gut would not serve as the central hub of health it’s known to be without the trillions of micro-organisms that make up our gut microbiome. Of these species, Lactobacillus strains are some of the most clinically researched and important organisms when it comes to supporting human health. SolBiome is a beautifully formulated, practitioner quality product containing science backed Lactobacillus strains that are known to support neuroendocrine function, stress, mood, digestive complaints, skin inflammation and so much more. Our relationship to these crucial species has developed over thousands of years, and in a modern era of living that seems to be far too busy to prioritise the gut ,SolBiome is a shelf stable, clinically significant and science backed multi strain probiotic that serves to bring balance back to every facet of your health.
