OptiBac 'For those on antibiotics'

For people who are taking antibiotics (e.g. amoxicillin, penicillin, tetracycline, doxycycline), or who have recently finished an antibiotic course, the strains of natural bacteria in this supplement are especially selected for their suitability and safety. These two high quality strains of natural bacteria, Lactobacillus acidophilus Rosell-52 and Lactobacillus rhamnosus Rosell-11, have been extremely well-researched, and are scientifically proven to survive to reach the gut alive, even during a course of antibiotics.

Antibiotics do not distinguish between friendly and harmful bacteria and are therefore thought to kill off much of the natural bacteria in the gut; this may often lead to side effects.

More about 'For those on antibiotics'

Lactobacillus acidophilus Rosell-52 is a natural resident of the intestinal microflora; this specific strain from OptiBac has been well studied to survive gastric acidity and bile salts expected at mealtimes and to reach the intestines without damage.

Lactobacillus rhamnosus Rosell-11 is a natural component of the friendly bacteria in the intestines; this species is one of the most studied in the world of live cultures. L. rhamnosus Rosell-11 has been proven to resist bile and gastric acidity over pH 3 - therefore if taken at mealtimes (when pH is around 4), it will pass through the stomach without being damaged.

These two microorganisms have been scientifically tested and shown to survive to reach the gut alive, and to be safe to take during your course of antibiotics.

Lactobacillus acidophilus Rosell-52

Directions

Can be given to adults and children (from 1 year and over) with the following recommendations:

  • Take one capsule daily with breakfast, *until antibiotics course is finished, and preferably for one week after.
  • Continue taking until pack is completed and add a second pack if the antibiotic treatment lasts more than one week.
  • OptiBac live cultures may be used on an ongoing basis.

*Can be taken at the same time as antibiotics - this product has been clinically trialled alongside antibiotics and found to reach the gut alive.

Note: Any customers taking particularly long-term and/or high strength antibiotics may want to consider taking OptiBac For every day EXTRA Strength instead. Also, for anyone unable to swallow capsules, the contents of the capsule can be mixed with a cold meal or beverage.

Storage

Like the rest of the OptiBac range, this does not require refrigeration.

Store out of direct sunlight.

Safety

Furthermore, pregnant or breastfeeding women should consult their doctor before taking Saccharomyces boulardii, 'For travelling abroad', or natural plant extracts as in 'For daily immunity'.

  • Bought probiotics for antibiotics recently. After consultation with Optibac they guided me through how to take them and also gave me advice for probiotics after treatment of Helicobacter. Treatment consisted of 3 antibiotics (very strong stuff). I am very happy to say after taking these every day with my treatment I had no diarrhoea at all and my stomach was comfortable. Can't thank enough. Am now using Saccharomyces boulardii and every day probiotics to increase benefits and protection. Telephone call guided me through.
    Thank you once again

  • I have problems taking antibiotics, I suffer with recurrent urine infections and by the third day they usually have me vomiting, the list of antibiotics I cant take is growing fast. It was my dentist who recommended I try taking these and for the first time I felt fine right to the last antibiotic. These probiotics are amazing and would recommend them to everyone, so glad I have taken them, I already bought another box for next time.
