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 normally take For Every Day but with the start of the nice weather I really wanted to feel on top form for wedding season and Summer fun ahead! I really think Extra Strength helps me reduce bloating and I just feel healthier and happier. I don't suffer from IBS or anything, I just like to take probiotics to feel nice and balanced. Really happy with the product!

  • Any one suffering with gastrointestinal problems please give these a try....
    I have been under the hospital for around 3 years now with constant really bad burning and cramp type pain in stomach morning day and night, to the point if I awoke in the night to feed little one within seconds it would start and I'd be unable to get back to sleep. I have had endoscopies done, biopsies taken, colonoscopies done and again biopsies taken and numerous medications. I have been told I have H-pylori which is what causes this gut problem, but despite numerous concoctions if different antibiotics taken simultaneously to get rid it still they're wreaking havoc. A year ago, hospital told me I was on the latest medication, maximum strength, and unfortunately, if this didnt help, there was nothing else she could give me, so stuck in pain until a new drug becomes available. None of these worked and seemed pointless taking them. Gaviscon took it off for literally seconds then back to constant pain in my gut 24/7. I read a book that discussed benefits of good gut bacteria and how everytime you have course of antibiotics it kills the good bacteria off, leaving you with more bad than good in your gut causing numerous issues. It mentioned to have above 10 billion a day so figured 20 billion should do the job nicely of storing my good bacteria stores back up. Within about 5-7 days my pain for the first time in over 2 years was lessening - only had pain around 4 or 5 times a day which compared to 24/7 this was a god-send. However, after 2 full weeks of taking them my pain was completely gone....literally. .... I couldn't believe the results! That was about 8 months ago and it's as come back on the odd occasions, but only if I've forgot to take it and missed for few days, or when I dropped to the everyday 5 billion which I thought I'd give a go as it's nearly half the price. After about a month or so on the lower dose the pain was back frequently. So I doubled these up on dosage up to 10 billion and after few days of doing this the pain was completely gone again. I also give to my 2 year old after spending 8 days in hospital end of last year with stomach bleed, amongst other things too, and she also suffers with gastric reflux disease. She had an endoscopy done. Constantly ill non- stop especially from September till end March when bugs are at their worst. Not one well day at all usually, until... last November when she was discharged I gave her the Extra strength for few weeks to build up her good bacteria, as she had an acute bacterial infection when in hospital as well. I then moved her onto optibac children's one and, touch wood, since end of November to date, she's only had couple of infections - nothing at all compared to how she usually is, and nothing too bad.
    I have told everyone about these who suffer with gut or immunity problems, although I have read the two are related - look after one and it will look after the other as well. I thank you optibac - you not only gave me my life back but my 2 year old's as well.
    Thank you.

  • Been using the Every Day Extra Strength for a week now and I'm shocked to be honest. I did go into this with an open mind wishing and praying it will work and I can say with 100% honesty is has worked... Read more
