    Customer Questions

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

    Should you take probiotics in pregnancy?

    Expectant mums may worry whether it's safe to take probiotics during pregnancy, especially as some other natural health supplements are not recommended at this time. However, Pregnancy contains probiotic strains which have been clinically trialed in pregnant and breastfeeding mothers and shown to be safe1; in fact it's advisable to support your gut with suitable probiotics at this special time. The strains in Pregnancy have been shown to offer potential benefits* for common pregnancy-related issues such as digestive health2, intimate health3 and immune health4 as well as supporting overall wellbeing6 whilst pregnant and into early motherhood*.

    How does this supplement differ to other probiotic supplements for pregnancy?

    Pregnancy contains specific probiotic strains which have extensive research to support their use all the way from conception, throughout pregnancy and into early motherhood2,5,6. Other brands often use the same strains of probiotics in all of their supplements, and simply add other ingredients to differentiate how they can be used. Unlike other brands, Pregnancy contains probiotic strains which have been researched during pregnancy, so there is no need for added ingredients. However, should you wish to take other prenatal supplements and vitamins, then it is fine to take your Pregnancy supplement alongside these.

    What are prebiotic FOS?

    FOS stands for Fructo-oligosaccharides and is a type of non-digestible carbohydrate. This means that it is not able to be broken down in the small intestines, and instead enters the large intestine where it acts as a fuel source for the bacteria living there. FOS is a prebiotic, which means it feeds our friendly bacteria, and helps to keep our microbiome healthy.

  • How To Use

    Recommended use

    Food supplement suitable for pregnant women from conception through to birth and for breastfeeding and non-breastfeeding women post birth with the following recommendations:

    • Take 1 capsule daily, preferably with breakfast.
    • For those unable to swallow capsules, open and mix contents with a cool drink / food.
    • Do not exceed recommended daily dosage.
    • May be taken on an ongoing basis or as professionally directed.
    • For best results use daily.

    Supporting Information

    Morning sickness and/or nausea is a common symptom in pregnancy and therefore pregnant women often prefer taking supplements in the form of capsules. To make taking Pregnancy capsules as easy as possible, we recommend tilting the head forward to swallow the capsule. Details below:

    • When swallowing tablets, it’s common to put the tablet in your mouth, drink some water and knock the head back to swallow it (i.e. look up before swallowing). Doing this uses the weight of the tablet to move it to the back of the throat and makes it easier to swallow successfully.
    • With a capsule, however, this won’t work because of the air in the capsule. Instead, while the capsule and water are in the mouth, we recommend to look down before swallowing. This will buoy the capsule to the top of the water (back of the throat) and make it easier to swallow, particularly if morning sickness and/or nausea are a problem for the individual.

    Storage instructions

    • For best results, do not remove desiccant sachet from the glass jar and close lid firmly after each use.
    • Store in a cool, dry place below 25°C (77 °F) and out of direct sunlight.


    Probiotics 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, short bowel syndrome, or patients with open wounds following major surgery; unless under a doctor's care. Keep out of reach of children.

    This is a dietary supplement and is not intended to prevent, treat or diagnose any medical conditions. Probiotic supplements 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.

    • I really suffered in my first pregnancy with bloating and nausea when taking other tablets. Since taking these with my second pregnancy I have noticed a considerable difference. It has also helped to keep my immune system up this time as I was catching all sorts of colds and bugs previously. Would highly recommend.

      Kirsty Roberts - 20th October 2021

    • I am in my third trimester and was really struggling with indigestion, bloating and gas. I was recommended these by a friend and I have found that my symptoms have really improved over the past month, I am no longer feeling uncomfortable and my digestive system is back on track. Since taking the probiotics, I have also noticed energy levels have increased as I was starting to get lethargic. I also love the fact that these probiotics are aiding my babies immune system too, especially during the uncertainty of the pandemic we are in.

      Harriet Gray - 10th September 2021

    • I am on my 4th bottle, I love this product and feel that it really gives me the support I need. I am currently breastfeeding and I find that my baby has a happy tummy as well after she feeds. She is now 9 months and I am on my 4th bottle. I can't exist without this. Thank you for developing something like this which helps us have a quality of life
