    Customer Questions

    All questions answered by probiotic experts Dr Kate Stephens PhD (Food and Microbial Sciences) BSc(Hons) Medical Microbiology and Kerry Beeson BSc (Nut. Med.) Nutritional Therapist.

    Should I take friendly bacteria every day?

    Yes, it is safe and generally advisable to take a daily friendly bacteria supplement. Good bacteria only colonise in the gut for a few weeks and research1,2,3 suggests that taking regular digestive supplements helps to complement the gut microbiome.

    Can you take live cultures long term?

    Some people like to take specific live cultures strains at certain times, for example during pregnancy, or during the winter flu season. However, most people prefer to take a daily live cultures supplement on an ongoing basis to maintain their gut bacteria. Research1 to date suggests that long-term use is fine, as the body does not become dependent on the good bacteria.

    How many strains is best in a live cultures supplement?

    The number of strains is not the most important thing to look for in a daily live cultures supplement. It is best to select a supplement containing highly researched friendly bacteria.  Optibac Every Day contains the world-renowned Lactobacillus acidophilus/helveticus Rosell-52 and Lactobacillus rhamnosus Rosell-11, proven to survive stomach acidity and reach the gut alive4.

    How does Optibac Every Day compare to other daily friendly bacteria supplements?

    If looking for alternatives to friendly bacteria brands like Symprove, you should compare the cost, the recommended daily amount, and the quality of the strains. A high-quality supplement always lists the full strain names of the bacteria, not just the species, which means you can check the supporting research. Optibac Every Day is a great alternative to Symprove and similar brands; it out-performs them not only on price, but also on quality of the strains it contains.

    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. Gut health supplements are natural food supplements and are not intended to prevent, treat, or diagnose any medical conditions. If taking friendly bacteria supplements for gut health, these should not be used as a substitute for a healthy diet and lifestyle. If you are taking any medications or have a serious medical condition, consult a doctor before use. Optibac supplements will not cause dependency and may be used on an ongoing basis.

    Following the taxonomic updates advised by a global team of scientists and published in April 2020, a reclassification has been proposed for the L. rhamnosus species. The Lactobacillus rhamnosus strain in Every Day may therefore now also be known as Lacticaseibacillus rhamnosus Rosell-11.

    • Good quality probiotics which have helped my stomach feel more comfortable. Quick dispatch and delivery

      Naomi - 26th August 2021

    • Always take the every day probiotics as I feel much better when I do. Just bought my new bottle and happy to find that they are now in a glass container instead of plastic, and I understand that all the Optibac products will be changed in due course.

      CW - 9th August 2021

    • Before I started taking Optibac 'Every Day', I was frequently bloated and the flatulence - my goodness! Faced with the number of products, I emailed for advice and received the most detailed, well explained reply from the Nutritional team leader, Camilla Gray, which surprised and impressed me. She recommended I start with 'One Week Flat', which I did, and by the end of the week, I noticed a difference, especially in the evening. I've now been taking the 'Every Day' for a month and I can honestly say its made a wonderful difference. Yes, there is still some flatulence, but, as she pointed out, that's normal. The main thing is, I no longer sound as if I'm the entire wind section of an orchestra! I want to say a big 'thank you' to Camilla for her advice and her follow-up email a month later (she asked first if it would be ok to email me again) to see how I was getting on. Such attentive customer service, which, sadly, is a rare thing nowadays.
