VSL#3 – High Strength Multi-Strain Probiotic for Advanced Gut Support

Most probiotic supplements on the market contain between 1–20 billion CFUs per serve, and often only a handful of strains. VSL#3 delivers a clinically validated 450 billion CFUs across eight specific strains of beneficial bacteria, all selected for their synergy and survival in the gastrointestinal tract.

It’s one of the most potent blends available and is backed by decades of research in areas like IBS, IBD, ulcerative colitis, and pouchitis.

This isn’t a general wellness supplement; it’s often used under professional guidance when more targeted, gut support is needed.

While incredibly effective, VSL#3 is considered a high-potency, practitioner-preferred probiotic. That means it’s usually best for people who have:

• A recommendation from a healthcare practitioner
• A diagnosed digestive condition (like IBS or IBD)
• Already trialled gentler probiotic strains without success

If you’re new to probiotics or sensitive to changes in your gut microbiome, we suggest starting with a lower strength option to ease your system into the shift. Our team is always happy to help guide you to the right entry point if you’re unsure.

Yes, VSL#3 must be refrigerated when it arrives to protect its potency. The bacterial strains in this formula are live and highly active, meaning they need a cold environment to remain stable and effective. The product is freeze dried and suitable for ambient transportation of up to 2 weeks without affecting the potency of the product.

We ship all VSL#3 orders in insulated packaging with cold packs to maintain optimal temperature during transit. Once your order arrives, pop it in the fridge right away for best results.

Yes, daily use is typically recommended, especially for those managing chronic gut conditions or looking to maintain microbial balance after antibiotics or illness.

Depending on your health status, your practitioner may suggest a tailored dose (such as 1–2 sachets per day). Because this is a high-strength probiotic, it’s always a good idea to check with your healthcare provider before long-term use.

VSL#3 is not vegan and may contain traces of dairy due to the way the probiotic strains are fermented. While it doesn’t contain milk as an added ingredient, individuals with severe dairy allergies or strict dietary needs should consult their healthcare provider before use.

If you're seeking a completely dairy-free probiotic option, we’re happy to recommend alternatives in our range.
