Horrible customer service
Good product, however, the company that distributes it in the UK is a complete and utter joke. This company, Nordic Pharma Ltd, is letting this brand down. I ordered probiotics to be delivered cold, but they arrived 5 days later, and the box was totally ruined. I tried to get in touch with them, and they are totally ignoring my messages. Basically, they take your money, and there is absolutely zero support.

This probiotic is absolutely amazing
This probiotic is absolutely amazing, is saving my life for the last year.
I have ulcerative colitis plus food allergies it was severe hard life before starting my use. I was suffering with a constant pain.
In the first week, I already felt response of my body getting better. And now I can say, I am having quite normal life again.
I am very glad and blessed to found VSL3.

Great, but expensive
I took vsl3 when taking antibiotics and have even gotten them for friends when they're on an antibiotic course. Keeps my digestion steady. They also had a good experience
It's expensive : ( . The purchasing process was good, no issues.
I got originally recommended these by a doctor so it gives me more trust in them.

It was recommended by my Docot
It was recommended by my GP as being helpful to my digestive issues. From a 3 month trial where I think it has helped I now have a 12month contract.
