Everyone suffers with digestive problems sometimes when eating different food on holidays abroad or even in certain restaurants here. A daily capsule of VSL3 stops any problems and is so easy to take. If the problem is more severe one could take 2 capsules or a sachet dissolved in water. I now have no worries when I travel abroad as Immodium etc is not the answer but VSL3. The service provided by the company is fantastic too.

It’s a wonderful product

It’s a wonderful product but the fact that it needs refrigeration can be a problem. Thankfully, we have good neighbours who put the package straight into our refrigerator.
I did think I’d asked for the product to be sent to the address we were staying and not our home address. That could’ve been my fault.

Game changer for my epileptic dog.

I had been giving VSL#3 to my epileptic dog after a recommendation from his neurologist.
He is on many drugs but still had multiple seizures every week and terrible stools.
After a gut test confirmed he couldn’t process protein and constant bought of diarrhoea I changed his diet to fish based and increased his VSL#3.
Retesting his gut shows a great improvement in diversity etc. 5 weeks later his stools are normal and this is the longest period without a seizure.

After years of pain this is a life changer

After years of pain, bloating and a plethora of other body reactions in response to foods and drinks; as well as private gastrointestinal tests, investigations and scans, I can honestly say that after taking this product for 3 weeks, my pain threshold has changed from a daily 95% level, to a 50% level. An ultimate life changer for me, and anticipating things continue to improve, in both my physical and my mental health.

Amazing Company

My parcel was lost and I had the new parcel within 48 hours. Brilliant service and company. The prebiotic are amazing. Try them, you won't regret it.

Helps my bloated tummy

This product definitely helps with my bloated tummy issues. Just wish it wasn’t as expensive as not sure I can maintain the cost long term

VSL#3 great quality

The product is top notch and the price is right - especially for those who have colitis disease or for those who no longer have a large intestine.
I love the packaging/shipping care.

In the afternoon of the second day of taking this I endured the most crippling stomach pains for five hours
I ended up crawling into a ball shape on my bedroom floor as I couldn’t lie down or stand as I was in so much pain
I have not touched the rest since

We're very sorry to hear that. Unfortunately, as VSL#3 is a food supplement we cannot advise on any specific medical condition and would kindly ask that you consult your healthcare provider.
Everyone's gut microbiome is different so what might work for most people unfortunately doesn't necessarily work for everyone.
