A life saver!
I started taking Optibac for women about 3years ago as a last resort to prevent the persistent UTIs I had experienced over the previous 2/3 years. It was magic, I haven’t had an UTI since!
I have a repeat order every 3 months which always arrives in good time. Customer service has been excellent. Thank you.

My experience
I’ve been taking optical products for several years on and off, due to a allergic reaction I had and was recommended by a hospital doctor to take them for a trial she was doing, results amazed me and I mostly take them now for hay fever in the spring.

All in all a terrible experience!
I am giving just the 1 star due to the terrible customer service that I received from Optibac when I attempted to place a repeat order for the Probiotics that I was taking. Despite my attempts to reorder the Probiotics I was unable to and, furthermore, I did not receive an explanation as to why I could not place my orders! All in all I had a very negative experience!

Dear Michael,
Thank you for taking the time to leave a review. I am sorry that you were disappointed with the customer service that you received from us. This is not the level of customer service that we expect, and I would really like to resolve this for you.
I have looked in your account, but I can't find any recent correspondence from you, would it be possible for you to contact us directly with some further details so that I can investigate this further?

I absolutely swear by Optibac
I absolutely swear by Optibac! A few years ago I was hospitalised with pneumonia and was very poorly. My nurse told me to get myself on Optibac speaking so highly of them. Since taking them I have not had one cold, sore throat or felt rubbish in any way.
From someone who used to be ill every Christmas to someone who hasn't been ill for three years. Says it all.
