  • Disappointed

    Took the capsules as instructed. Had a bad stomach the first week away and had to visit the doctor. Really disappointed after reading such excellent reviews.

    Dear Anna,

    Thank you for taking the time to leave us your comments.

    I'm so sorry that you feel our travel product didn't work for you; however, ultimately these are food supplements and we can't make any guarantees as to their efficacy, as everyone will be different in response to medication, foods and health supplements.

    'For travelling abroad' is a special formulation designed for convenience where suitcase space is limited, with a view to reducing the risk of 'traveller's tummy' when travelling to exotic countries where stomach upsets are common amongst tourists. We have thousands of customers who have used this product and reported a very significant benefit from doing so.

    Ultimately, however, digestive upsets of this kind can occur for a variety of reasons when visiting a new environment: consuming new and unfamiliar foods and drinks, dehydration/heat exhaustion, and travel sickness as well as exposure to pathogenic bacteria. It's still wise to take every precaution with hygiene and food choices, and use the product as part of a considered approach to avoiding ill health on holiday.

    If they have specific health needs, some of our customers may take other products from our range on holiday with them, as they are all shelf stable and do not require refrigeration - you're welcome to call our advice line before your next trip to see if any other product combination would be more suitable for you.

    We appreciate all customer feedback, however, which we take very seriously and I will log your comments with a view to improving our product range still further.

    Thanks again for your time, and your interest in our products.

    Wishing you the best of health,

  • Optibac saccharomyces

    A fantastic product. Ive struggled for years with candida and digestive disorders and had been advised to try this as it is supposed to boost the antibody production on the intestinal walls. For the first time in years symptoms have abated and I feel it will be possible to fully recover!

  • Impressed

    I was told about probiotics by a friend and after a lot of research I found that Optibac seemed like they were in line with what all the medical experts were saying in their reports. I'm using Optibac probiotics for my 3 month old - started when he was around 8 weeks- and after a week of giving one sachet a day to him I started to see noticeable improvements to his wellbeing, his eczema vanished, his bowel movement improved and became regular and he's been benefitting ever since. Definitely recommend especially if your baby was given antibiotics after birth.

  • Great product

    Optibac is a great product to promote regularity. One packet a day or every two days is enough.

  • Best delivery time I have experienced

    Can't be certain without medical opinion but I believe the recent month course of Probiotics has eased my flatulence problem.

  • Has completely cleared up eczema!

    Very happy with the product, I always knew allergies from certain foods were the cause of my eczema flare ups, and going by the areas affected were on my cheeks which on reflexology of the face relates to the stomach I knew this first was the area that needed treating, naturally. Within 2 weeks my skin had cleared up, amazing and very happy! Thankyou

    Dear Carol,

    Thank you so much for taking the time to review our products, and I'm delighted to hear that you've found such a benefit from using them.

    I'm so sorry that you had a problem ordering through our website - our highly efficient IT department are constantly updating the system to ensure that it's quick and easy for our customers to use. In this instance, the technical team had to investigate the issue you were having before calling you back, and were able to deal with the issue within a few hours, but I'm sorry that this was not quick enough for your needs and I'm glad you were able to source the products from elsewhere to avoid any delay.

    Thanks again for your review, and your interest in our products.

  • 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 ;)
