  • Good service from this company

    Good service from this company. However I have to say that I really cannot say that any of the products I have used have shown any particular benefit to me.

    Optibac are the best company to get probiotica from. Well researched strains that produce results. You just need to find what suits you. If you are female, at some point, you may need the 'for women' one. It is brilliant. Does exactly what it says on the tin.

  • Response from OptiBac Probiotics

    Dear Adrian,

    Thank you for your valuable feedback.

    I'm so sorry that you are disappointed by the recent changes to our product, 'For every day', which included changing it from a 'two per day' to a 'one a day' format. Most customers have welcomed this change, as it means less capsules for them to take each day. I appreciate that you were taking half of the dose and found this to be effective for you, but the product was always intended to be taken at a dose of 5 billion live cultures per day.

    The change was also made to enable 'For every day', along with the rest of our range, to be transferred into new, ‘state of the art’ CSP pots. The new pots offer such an improvement to the quality and long-term viability of the probiotics that we felt that making the change from two capsules to one was more than worthwhile.
    This is particularly useful for international customers such as yourself, who are shipping the products long-distance, to ensure that your products are kept in a very stable environment during transit.

    If you still wanted to continue taking the product, however, do remember that all of our encapsulated products can be taken out of their capsules if desired, allowing you to divide the contents as you wish, into cool milk/water, yoghurt or direct into the mouth. You can also consider taking the products every other day if desired, and see how this works for you.

    Once again, thank you for your comments, and I hope that you can still continue to use your favourite OptiBac Probiotics product.

    With kind regards,

  • Response from OptiBac Probiotics

    Dear Cheryl,

    Thank you for taking the time to leave your feedback. This is always much appreciated.

    I'm sorry that you experienced a painful stomach whilst taking this product: this is very unusual feedback as probiotics are usually tolerated very well by the majority of people. These are natural food supplements and not medicines, and so side effects from taking probiotics are extremely rare. A large number of clinical studies highlight that our probiotic supplements are completely safe for human consumption, and research shows that it is very difficult to overdose on probiotics.

    It's particularly unusual for you to have experienced digestive effects, as the product that you were taking contains strains of bacteria that are known to colonise in the female intimate area, rather than in the intestines. For this reason, it's always worth considering whether the symptoms were caused by other factors, such as new foods, other supplements or medications.

    If you're sure that the symptoms were connected to the product and would like more help and advice about getting the best from your probiotics, or you'd like to make sure that you're taking the right product for your needs, then don't hesitate to get in touch on [email protected]

    Once again, thank you for taking time out of your day to share your experience.

    With kind regards,

How we collect customer reviews


Our probiotic reviews are collected primarily through an open review community called TrustPilot. Using this independent service affords our customers a chance to hear from other real customers who have tried and reviewed our probiotics.

Our probiotic reviews collected through this service are verified to come from real customers meaning they are unbiased and trustworthy.

Our website

We also collect reviews on our probiotics directly on our website. This is a useful way of offering customers who purchase our products from independent retailers (are not verified to have purchased from us directly) a chance to leave feedback and share their success stories.

Using our website, both customers who are verified to have purchased from us directly and customers who may have purchased from other sources can both leave reviews and feedback on their experience with our products. Visit our online shop to review any of our probiotics you have taken.

  • 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 ;)
