Best and most effective probiotics I've tried
These probiotics work so well for me. Game changers. Pity they are so expensive now thanks to the NHS.

Excellent probiotic
I’ve used VSL for years - it’s always been an effective treatment. Research shows its efficacy. With the money.

Great product, poor delivery
The product is great, but it was left in the rain in a cardboard box without notification

This thing works - no gimmicks
The capsule form is very practical and the most concentrated probiotic you will find.

They work!…
I would not be without these probiotics. They have settled my IBS so I no longer have the cramps and diarrhoea or constipation and feel more in control. Highly recommend them

Positive feedback from new user
As a new user, i'm finding VSL3 - in conjunction with a prebiotic - is beginning to make a difference. Gut seems healthier and more under control

I had an outstanding experience with this credit company. The team was extremely professional, helpful, and patient throughout the entire process. They explained everything clearly, offered the best options for my situation, and handled my application quickly and efficiently. I truly felt supported and well taken care of.
Highly recommended to anyone looking for reliable and trustworthy financial assistance!

Delivery with Royal Mail 48hr tracked…
Delivery with Royal Mail 48hr tracked is appalling! Order placed on a Wednesday evening - tracking said it was being delivered on the Friday so stayed in all day waiting, as well as all day Saturday - yet no delivery! Have had to get it redirected to a post office collection point to ensure it is delivered. Received it on Monday - 5 days after order was placed. These are expensive live probiotics which degrade when left out of the fridge, so 5 days! Very disappointed and now question the quality of the product received which has been purchased for someone who suffers with Crohn's Disease!

VSL# doing well, Royal Mail delivery not so good
VSL#3 has been a game changer for me, calming my system down before my pancreatic Insufficiency diagnosis. Now I will take it on a regular basis to keep my stomach easier to cope with.
Royal mail were late with my delivery, despite giving a delivery time.
