Background Information

The human body is naturally home to both good and bad (pathogenic) bacteria, and keeping a healthy balance is thought to be an important factor in supporting healthy digestion and immunity. However, the body's intestinal balance of good and bad bacteria is delicate, and can easily be upset by factors such as antibiotics, stress, ageing, and diet.

People with a severe imbalance of good and bad bacteria in intestines may include:

  • Those on long term antibiotics
  • Those who suffer from conditions such as IBS, or IBD (eg. Crohn's Disease)
  • People with skin conditions such as eczema or acne

  • I'm not one to write reviews HOWEVER, I have been suffering from severe gastritis for almost 7 years; I've had all sorts of hospital procedures including 3 EGD's and 2 colonoscopies all of which came back 'normal'. I'm a young 29 year old, petite framed woman, but for 7 years I've been constantly bloated and in pain. I'm so bloated that people often think I'm pregnant and offer me their seat on the train! I reached the point of desperation and depression. Over the years, I had been to several natural nutritious and Chinese doctors, I tried so many things!! Then one day I was in my local health food shop and I was telling a shop assistant about my chronic condition that was ruining my life and he advised Probiotic 'Every day, Extra Strength' so I bought them immediately and HONESTLY, within about 5 days or so. All my symptoms were gone!!!! I could not believe it!!! All these years of tests, inflammation, bloating and chronic fatigue and it all came down to a probiotic. I was actually completely taken aback.
    I'd advise these to anyone going through gastrointestinal issues like me. Just try it, it's natural and non harmful. Of course, we are all different, so my experience could be different to yours. But I'm almost certain that even if they don't work, they definitely won't harm you, so it's worth a try.

    A month in and I'm now on a course of strong antibiotics for a separate issue. Immediately after taking my first dose, my stomach puffed up and I got acid and cramping for the first time in a long time, I'm now taking 'probiotics for those on antibiotics' it's only day 2, so hopefully I'll be back here in 10 days or so with a review on them. After I'm done with these, I'll be back on the 'Every day, Extra Strength' again.

    Thank you v much Optibac, keep doing what you're doing. It really really helped me.


  • I have been taking Optibac probiotics extra strength for just over a week and I must say they have transformed my life. I had at least four courses of antibiotics six months ago and I am sure they did awful things to my stomach. I had been in agony for months. I read about these probiotics on the Internet and since taking them have never looked back. As we speak I am ordering my next delivery. Thank you so much.
