We bought the gummies four children

We bought the gummies four children, they loved the flavour and texture. We used to give them a chewable type, but children didn't like the flavour. Will recommend it to families who like to have probiotics for their children.

First Class Customer Service

I had no prior knowledge of the Optibac products so I booked a 1:1 telephone consultation and I couldn't have been more satisfied with the professional and efficient communication and constructive advice as to which product would suit me best.

Not good service but products okay

At the time of ordering I asked several questions in emails. They briefly answered the most urgent questions about delivery etc but ignored the rest.

I've tried the 2 products I bought. I was hesitant about taking the yeast one without getting answers but started taking 2 days ago when I realised answers were not forthcoming. Noticed a little difference so far with both. So far so good.

Dear Kelcie,

Thank you for taking the time to share your feedback with us, and I'm sorry that you did not feel all of your questions were answered.

I can see that you left a note on your order asking if the products were dairy-free, and my colleague Paula emailed you to confirm that they were. We cannot find any other correspondence from you unfortunately.

If you still have questions about the products we would love to help, so please do reach out to us via the contact form on our website, Live Chat, or you can book a free call with a member of our Nutrition Team.

We look forward to speaking with you soon.

With Best Wishes,
Charlotte, Nutrition Team.

Optibac- health care assistance.

Used to sell Optibac products in the health shop where I worked and now after a course of strong antibiotics I am confident in the product to do exactly as it claims and help to rebuild my good gut bacteria and so boost my immune system. I still recommend Optibac to anyone suffering from digestive, urinary, female health or just general low immunity problems.
