  • Prompt delivery but expensive products

    I can purchase the same products from the USA and have them shipped over for less. However if you need them quickly then no problems here at all and I would use again.

  • Didn't work as well as I expected them to

    Myself and my husband recently travelled to Egypt and took the tablets exactly as described on the leaflet. The tablets did not work as we both got an upset stomach 3 days into our holiday. I was convinced these tablets would work because of how good … Read More

  • Response from OptiBac Probiotics

    Dear Laura, thank you for your feedback, yet I'm very sorry to hear the product didn't work for you. As you say, the feedback is normally excellent for the travel probiotic, but I suppose each person is different and with food supplements one can never find a 'cure-all'. If you would like to talk about other options in terms of probiotics, or perhaps to try a different product from our range, with our compliments, please email us at [email protected] I hope you are both feeling better now, and I hope the products work much better next time!

  • Better bowel health (and fewer diverticular symptoms)

    It makes sense to promote well balanced gut flora if 70% of your immune system resides there!

  • Great company, will buy again.

    First of all apologies for previous revue, where I mixed up two great products/companies. My excuse :- I received TWO requests for revues immediately following one another, AND I'm not used to doing revues, so got them mixed up. VERY SORRY OPTIBAC.So, the revue, product was received promptly, easy to get into (can be a BIG problem when like me you have arthritis in fingers)Have been taking the probiotics for a while now and am very pleased with the result. I ordered following reading an article in WDDTY on bifido-bacteria and problems with weight loss even though eating healthily. I can only say 'It works!' As a (now retired) therapist, I knew the healthy way to eat, and had struggled since the menopause, having previously been slender my whole life.I'm finding it much easier now, and weight is gradually coming off together with reduction in waist measurement. GREAT!!

  • DID NOT SUIT ME AT ALL

    I started using the capsules and immediately experienced bladder problems which required antibiotics to rectify, after finishing the course I decided to give the probiotics another shot on the premise that it was an unfortunate coincidence,but a s so … Read More

  • Response from OptiBac Probiotics

    Dear Rob, thank you for you review, and I'm very sorry to hear that you felt the product didn't work for you. we've never had this feedback before, in fact if anything, research suggests probiotics should help with bladder problems (certainly any bacterial infections) and not make them worse. If you would like to speak to one of our nutritional therapists please don't hesitate to contact us on 01264 363 193, or email us at [email protected] Best wishes, Soraya

  • Gave me confidence!

    Have been getting recurrent bouts of a bacterial infection in my jawbone,the dentist has put me on anti biotics and then I read in the Dail mail about taking Optibac Probiotics with the anti biotics to boost my immune system.I sent away for 2 packs which arrived the following day-how is that for service-i have taken them and touch wood-feel that they might have been a big help in boosting my immune system.

  • SO FAR SO GOOD

    I suffer with frequent episodes of bladder infection and during the last episode, I happened to read an article on the benefits of probiotics in The Daily Mail. The article was recommending Optibac Probiotics, saying that in tests, they were the only probiotics to find their way alive through the stomach into the gut. I checked out the site and found that they had a new product, specifically for women, helping to maintain the good bacteria in the bladder and reproductive system. I immediately ordered a supply of these and am now into the second month of treatment. It is early days but I am well at the moment and I will continue to take one capsule a day in the hope that the good bacteria will fend off the bad which causes the infections. My order was dealt with promptly and efficiently and it was received in a matter of days. The website was very simple to navigate. I would definitely recommend the company and the product, which could hopefully provide a solution for many female sufferers.

    The product arrived promptly, was as described and will hopefully in the long term be effective.

  • Fantastic product and am happy that the probiotics survive stomach acid since many on the market don't!

    It's nice to finally see a company doing as much as possible to improve probiotics. I am under the impression that Optibac takes their research seriously and am very pleased to see that they are offering such a good range of probiotic products. We use them for the whole family and we all feel a lot better for taking them!

  • Reliable and transparent service.

    Please change your packaging so goods can be posted through letterboxes and no need to collect from a delivery point. Other companies do this with same type of goods.

  • Response from OptiBac Probiotics

    Dear Mark, thank you for your feedback, glad you are happy with the products. We package the products according to a number of factors, including best positioning for the health food shops (our main route to market), the pricing (so we can keep to good value) and most importantly, the stability of the probiotics (eg they need a certain type of plastic, with routine quality tests, to ensure the delicate bacteria remain stable and live) so regarding packaging, it can be difficult to tick every box. However perhaps we could offer a service on our website to remove the packaging and offer more of a 'flat pack' system where possible. I've passed this on to dispatch and we will discuss it. In the meantime I hope you are able to provide a delivery address (such as a workplace) where someone is available to collect your package. Best wishes, Soraya

  • I unfortunately have a problem using the everyday optibac. After several days of use I suddenly developed more frequent bowel movements. I stopped taking them for several days and then restarted. I think it could be the prebiotic, have had to discontinue use. Very disappointed.

  • Response from OptiBac Probiotics

    Dear Anne, I'm so sorry you experienced these symptoms. It's not something we hear often at all, so I wonder if I could ask some further questions? Did you start taking 'For every day' for any particular reason? When you say the bowel movements were more frequent - I wonder how frequent this was, and if the consistency was also altered? Occasionally we do have some customers who are sensitive to prebiotics, but they usually find after 3-4 days that their body becomes used to it and things settle down. We recommend 'For every day EXTRA Strength' as an alternative, as it doesn't contain prebiotics. If you'd like to chat about this further please email through your phone number to [email protected] and I'll give you a ring. - Megan, Naturopath & Herbalist

  • As a nutritionist I have been prescribing Optibac Bowel calm to a number of my IBS patients lately and it has proven very successful as a treatment for chronic diarrhoea so I'm delighted with this product and very interested in testing out other products in the future

  • Having suffered with IBS since I was a teenager (approx 30 years) I have tried everything to try and get it under control. Over the last seven months it has worsened, possibly due to stress of two house moves, a relocation and a new job. On the worst days I have been unable to leave the house for fear of not being near a toilet. I read up on probiotics again (I had tried them before but with not much success) and discovered your website. So I thought I'd give them another go and ordered the Bowel Calm and the Daily Wellbeing Extra. What can I say? I am absolutely amazed. They arrived on Friday, on Sunday my husband and I went for a 6 mile walk, something that hasn't been possible for months. I am so glad I have found these products, they really are starting to put an end to years of misery! Thank you.

  • I gave my 6 month old girl Optibac Probiotics for her severe eczema. She had already had two infections and two courses of antibiotics at 4 months and 5/6 months but the second course was taken with probiotics and she has not had a skin infection ever since. Considering the severity of her eczema (two GPs saying it was the worst case they'd seen) this is amazing. She is now 1 and still taking daily sachets of Optibac, her eczema is clear (also thanks to the right steroid cream I should add) and I cannot thank them enough. She is also never ill (touch wood) despite her 4 year old big sister bringing home various preschool bugs. Her immune system has been given the boost it needed and then some - I recommend Optibac to everyone, they think I must be on commission! Thank you once again, and especially thank you to Steve Payne who recommended them in the first place and even purchased our first sachets for us. So grateful.

    Thanks for the review Katie, we'll be sure to pass the message onto Steve.

  • My husband and I have used several of Optibac's excellent products. We can recommend Bowel Calm and Well being in particular for helping to keep your digestive system on the right track. I've also taken the Extra Strength versions from time to time when a harder hit of probiotics is needed. We all suffer from an upset tum from time to time, and I've found that taking this great product can nip it in the bud. Things are usually back to normal within two or three days. These are excellent products with an excellent team of advisors behind them. Recommended to one and all.

  • After a course of tablets from my doctor I began suffering from diahorrea to the extent i was worried i had IBS. A friend who promotes organic foods "a little too much" recommended probiotics. After the second tablet of the extra strength ones my bowel movements were back to normal. I claimed co-incidence until 6 months later it cured the same problem again. I am a chartered engineer and not taken in by gimmick tablets. I hate to say it I now swear by these tablets

  • Two of us took them as prescribed and had no problems while in China. 3 days after stopping them I got stomach cramps, lasting for over a week. I later found out that this happened to my friend as well. I wonder to what degree they take over the system and whether there should be a gradual winding down of them.

  • Response from OptiBac Probiotics

    Hi Dave, were you taking the travel probiotic? I must say that this feedback is completely unprecedented. Generally speaking there is no need to 'wind down' after probiotics, and they certainly should not cause stomach cramps. If you would like to discuss further please call us, 01264 339 770, perhaps we can offer you a different product to try next time. Warm regards, Soraya

  • after years of holiday tummy every time i travelled away from home i tried travla. we holidayed in india & i ate salads,fruit, seafood & everything your recommended to avoid, i have to say my tummy has never been more settled & i felt generally better all round.

  • I also wish these products were available in Australia, but I am happy to order on line to receive them from you. Thanks.

  • Your website is an inspiration, easy to navigate and love the 'latest news' giving up-to-date findings on trials and research. Thank you so very much

  • I am very pleased with your products. I have always had a 'nervous' stomach to go along with asthma and later in life horrible eczema. Many years ago I got serious poisoning from of all things bad potatoes, and since then my life has been truly wrecked by being so ill. I must have ingested kilos of lotomil and loperamide. Even though I do drink litres of water enthusiastically I very often would be in a horrible state of dehydration. Everything seems to get me, many foods, stress and worst of all I have a bad allergy to aspirin and salicylates which is very difficult to get around as they're everywhere. ...I had heard that this probiotic range is good and I just went for it. I really don't buy into the drinks as being that helpful but the information about the products on your website gave me hope. I bought the For daily wellbeing, the For daily wellbeing EXTRA Strength, and For bowel calm. I have taken the EXTRA Strength and the bowel calm so far and am almost euphoric! I am very much looking forward to the new regularity product as it gives me a feeling of saftey to have products I can use if there's an emergency and the extra strength, bowel calm and regularity products should keep even a nervous Nelly like me happy. I feel so good after what was an awful weekend and I just can't stop smiling. ..Thanks for the excellent backup as well as the products. Kean.

  • I really love OptiBac and I really miss it here. There are no substitutes which could compare to it in Australia.

  • My healing practitioner Gabriele A. Franklin recommended to me all kinds of OptiBac products a long time ago. For the last 4 years they have become a firm fixture of every day and I'm satisfied with your high quality products. When I hear about friends on antibiotics, OptiBac's the first word leaving my mouth ;)
