  • A great product

    A great service, and product. They help to counteract the effect of having to have antibioticsFairly regularly. I wish I had known about these earlier

  • Changed my ife

    I have consistently had sluggish bowels for the past 30 years (lucky if I went twice a week) which often made me feel ill and lethargic and as a last resort I had colonic hydroptherapy 4 months ago. At that appointment I was recommended to use OptiBac Max. I have taken them daily since and have become "regular as clockwork" - opening my bowels every morning . I now have much more energy. Optibac has changed my life.

    Dear Carol,

    Thank you so much for taking the time to leave your feedback, and I'm delighted that you've found such a positive benefit from using the product!
    That's really great news.

    To avoid any confusion for other customers, I'll just point out that the product you purchased is called 'For every day EXTRA Strength' rather than 'OptiBac Max'.

    Wishing you continued good health!

  • Everything perfect

    The tablets must have been posted immediately as I got them the next day.I began to feel more energy within a few days and lots of small medical issues cleared up in a week or so. I shall keep buying them from this company

  • Disappointed

    Purchased for a 7 month baby after antibiotics but had to stop due to too many bowl movements and a very sore nappy rash. Still waiting for information from optibac as to why the probiotics caused that reaction.

  • Really helped by 'For Women.'

    I have been taking For Women for 2 months and I feel more comfortable, after years of discomfort and recurrent thrush and cystitis. I have had to take antibiotics on 2 occasions but taking OptiBac for women really supported me and avoided the awful discomfort of getting thrush!

  • It works in many ways

    Perfect, helped my tummy, skin and general well being. It is my normal modus to avoid giving recommendations but with this product I do to any I think may benefit from it. My only gripe is they could use slim packaging that fits through letterboxes for postal deliveries.

  • Amazingly quick improvement.

    Good information on website concerning company background which inspires confidence in their products. I have already repurchased as I experienced an immediate improvement.

  • Probiotics that really work

    I've tried a lot of probiotics in the market but never really saw a difference . But when I started optibac probiotic for flat stomach my bloating improved significantly .. Will definitely continue n recommend to friends and families ..

  • This really does work!

    I go through phases of feeling bloated and uncomfortable, so was tempted to try the OptiBac 'one week flat' probiotic pack. It had an immediate impact from the first morning I took it - didn't get rid of the flab obviously, but I definitely completely lost that bulgy bloated feeling, and my clothes instantly felt so much more comfortable. This is a no-fuss product that gets straight on with its job.

  • 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 ;)
