  • I regularly use this product if my clients have to go onto antibiotics I have, on occasion, used this myself too - as well as S Boulardii. Great products from Optibac.

    Nicola Warran- 29th June 2022

  • How to use

    Recommended use

    Food supplement suitable for adults and children, from 4 years onwards, with the following recommendations:

    • Take 1 capsule daily with food, preferably with breakfast, every day during your antibiotic course and for a few days afterwards or until the pack has been completed.
    • Can be taken at the same time as antibiotics - strains in this product have been clinically trialled alongside antibiotics and found to reach the gut alive.
    • Drink plenty of water with your course of live cultures.
    • For anyone unable to swallow capsules, open and mix contents of the capsule with a cool meal or beverage.

    Storage instructions

    • Store in a cool, dry place below 25°C and out of direct sunlight.

    Safety

    Live cultures are not recommended for those with serious medical conditions e.g. those who are severely immunosuppressed, have pancreatitis, are in the ICU, have melaena, have a central venous catheter, infants with short bowel syndrome, or patients with open wounds following major surgery; unless under a doctor's care. Keep out of reach of children.

 Yes! Taking live cultures with antibiotics is highly recommended.  However, it’s important to select supplements such as Optibac For Those On Antibiotics, which contains strains extensively researched (1,2) alongside this type of medication and shown to reach the gut alive.

Live cultures are best taken with food, ideally breakfast, when stomach acidity is closer to neutral. Antibiotics present an additional challenge for most delicate good bacteria, but if you take specific live cultures for antibiotics, such as those found in Optibac For Those On Antibiotics, they are hardy against the effects of this treatment (1) and continue to complement the gut microbiome throughout the course. This means you can still take your friendly bacteria supplement with breakfast as recommended, regardless of when you take your antibiotics! Taking these specific live cultures makes life easy - other live cultures supplements need to be taken at least two hours away from the medication.

Antibiotic medication can harm most delicate live cultures, so it’s best to choose specific friendly bacteria for antibiotics. Strains such as Lactobacillus acidophilus/helveticus Rosell-52, Lactobacillus rhamnosus Rosell-11 and Bifidobacterium lactis Lafti B94 have been shown to reach the gut alive, even when taken at the exact same time as short or long courses of antibiotic medication (1,2,3). These strains can be found in Optibac For Those On Antibiotics.
