I was introduced to De Simones VSL#3 two years ago after a bad digestion issue. A consultant suggested it. Moved to Vivomixx as couldn't get in UK. Saw it is now available under De Simones own label again and switched back. It suits me better and dissolves more easily. Would recommend to anyone with IBS.

Finally found the real thing! I used to take the De Simone probiotic in Korea, but since moving to the UK I could never find the same product. I struggled with constant bloating and severe constipation, which was exhausting. Eventually I discovered a small family-run brand still using Professor De Simone's original formula, unlike the big corporate version with just the same name and packaging. After only a week of taking it, the change has been incredible. I finally feel like myself again. If I had to recommend just one probiotic, this would be it.

Thanks to probiotic.co.uk. I was struggling to find the original De Simone probiotic formula for sale in the UK and probiotic.co.uk to the rescue! Easy to order, relatively good value if you bulk buy and the package arrived as expected. Their customer support has been great too on the odd occasion I've emailed them with queries regarding other products. The probiotics have made a huge difference to my health and day to day wellbeing.

Four things customers keep telling us

These are the themes that come up most often on our Trustpilot profile. Not marketing lines, just what people keep writing.

Availability

The original formula, in the UK

The theme that comes up most. Reviewers spent years unable to source the De Simone Formulation in Britain. We hold the exclusive UK and Ireland distribution rights for CDS22-formula.

Delivery

Next-day, UK wide

Dispatched from our Lancashire hub via Royal Mail 24 or DPD, cold-chain protected to the door. We ship to all of the UK including Northern Ireland.

Cold chain

Stock arrives fresh

Live cultures are held in a temperature-controlled facility and packed to minimise time outside controlled conditions. Reviewers note fresh, long-dated batches.

Support

A real person replies

Specialist email support from the team that runs the company, not an outsourced desk. Order questions and product queries are answered directly.

Our review policy

Why you can trust these reviews

Anyone can claim five stars. Here is exactly how ours are collected, so you can judge for yourself.

  • Reviews are collected and hosted by Trustpilot, an independent platform. We do not host them ourselves.
  • Invitations go to real customers after a real order. We do not buy, incentivise or solicit reviews.
  • We cannot delete a review. We can only report one to Trustpilot if we believe it breaches their guidelines, and Trustpilot decides.
  • Negative reviews stay published. We reply to them rather than remove them.
  • The rating and review count on this page are pulled live from our Trustpilot profile, so they are never out of date.
The founders of Probiotic.co.uk

Who you are buying from

Still a family business. Not a small one.

Who we are

Probiotic.co.uk is run by Darren and Vivien Grant, with their daughter Zoe and a dachshund named Jazz who holds the title of Head of HR and does very little to earn it. The UK company is TenX Tech UK Ltd.

Where we are now

We hold the exclusive distribution rights for CDS22-formula, the original De Simone Formulation, across both the UK and Ireland. That is a signed agreement, not a reseller arrangement. We run two stores, probiotic.co.uk here and probiotic.ie in Ireland, with fulfilment in both countries.

What that means for your order

We buy direct from the manufacturer. No grey imports, no middlemen, no stock that has passed through three warehouses on its way to you. Everything ships from our temperature-controlled hub in Chorley, Lancashire, cold-chain protected to your door.

Same people answering the email

We have grown, but the company is still owned and run by the same family, and your email still lands with one of us. Reviews are how people decide whether to trust us with an order, so we still read every single one.
