OptiBac Probiotics 'Bifidobacteria & fibre'

'Bifidobacteria & fibre' (For maintaining regularity) is a natural supplement containing carefully selected microorganisms and fibres.  Bifidobacterium lactis BB-12® has seen extensive scientific and clinical research, and is thought to be the world's most researched strain of the entire family of Bifidobacteria.   What's more this high quality strain is scientifically proven to survive stomach acidity and biliary salts to reach the gut alive.  The ingredient Fructooligosaccharide (FOS), makes this product naturally high in fibre. FOS may act as a food source for the body's natural bacteria, and as roughage in the bowels. 

OptiBac Probiotics 'Bifidobacteria & fibre' can be taken once a day for ongoing maintenance; or as and when desired, in which case we recommend taking up to 4 sachets a day.

Thanks to the high amount of natural fibre in this supplement, it may be especially suitable for those with constipation. 

Constipation affects in particular:

  • More women than men
  • Some people whilst travelling
  • Infants & children
  • Pregnant women
  • The elderly

'Bifidobacteria & fibre' (For maintaining regularity) is a safe and gentle food supplement.  It is appropriate for long-term use, can be taken by infants from 1 year and up, and is gentle enough for pregnant & breastfeeding mothers, as well as the elderly.

    "I have, for several years, been plagued by what I believed to be idiopathic constipation. I tried all sorts of stool softeners, resorted to laxatives, drank copious quantities of water and conscientiously watched my diet, neurotically gorging on fruit, veg and cereals. Nothing seemed to work at all and I feared I may have some sort of dread disease. At one stage, I even ordered an online bowel cancer test which, thankfully, came up negative. I was too embarrassed to go to my GP, so I just put up with it, fearing the worst. However, the other day it suddenly dawned on me that, following years of being on 1000mg of Oxytetracycline for about four years, to treat rosacea, I had probably compromised my gut flora. I do recall asking my Dermatologist if this were possible but he dismissed my enquiry saying that Oxytet is the 'gold standard' treatment for rosacea and, no, it would not cause constipation. Now, I disagree. On a bit of whim, combined with some 'gut instinct', I bought Optibac probiotics a few weeks ago and I can only say that the transformation in my gut has been nothing short of miraculous! I have already lost a kilo in weight, I have started having normal bowel movements and I am not feeling as bloated or uncomfortable as I have become accustomed to. In short, I feel amazing and I want to thank the Optibac researchers hugely. I bought the probiotic for maintaining regularity (30 sachets now finished) and I have just ordered the flat stomach formula and the Extra strength daily wellbeing formula. I only wish I had come across these a long time. Thankyou!!! "

    "I have had constipation from last three years and I have tried everything possible on this earth fro fibre to laxative to all kinds of teas. I have been dependent on laxative. After my pregnancy, I was not allowed to use laxatives on daily basis and my condition was getting bad.

    I heard about Optibac and tried. I was surprised that in the first five days only my problem was solved upto 70%. I would wake up every morning and go to toilet without any laxatives. I cannot share the relief I felt and I am happy that I am not harming my body and baby.

    Thank you Optibac and special thanks to Megan form Optibac who advised me in the selection of right Optibac for my condition."
