With so many brands to choose from, it can be difficult to choose the live cultures supplement that’s right for you. We recommend looking for good bacteria which is guaranteed to reach the gut alive, contains well-researched strains, is shelf stable and does not need refrigerating. It is always good to choose a product with great customer reviews, but most importantly it should contain strains researched especially for your needs.
When it comes to friendly bacteria, ‘more’ is not always ‘better’. It is more important to consider the quality of the good bacteria strains, and the number of gold standard clinical trials they have been featured in. It is also very important to ensure that this research is relevant for your individual needs. High-quality supplements containing well-researched strains will contain the same number of billions used in clinical trials: some studies suggest that lower dosage have more significant effects, and therefore there is no point in offering a higher strength product (usually at higher cost) when the same effects will be achieved with a lower dose.
Please note: This is a food supplement and is not intended to prevent, treat or diagnose any medical conditions.
No refrigeration necessary when stored in a cool, dry place below 25°C.

Yes, it is safe and generally advisable to take live cultures daily. Good bacteria colonise in the gut for a few weeks but research1,2,3 suggests that the good bacteria strains will disappear without regular supplementation, so for this reason you might wish to take them regularly.
The concern is that bacteria are delicate by nature, and that they may not survive stomach acid. Taking live cultures at a certain time of day (when stomach acidity is closer to neutral) could help ensure the highest survival rates of the good bacteria. Confusingly though, different healthcare professionals and live cultures manufacturers have different guidelines about when is best to take these supplements! So, let us try to clarify a few things.
First, let us look at the logic behind taking live cultures on an empty stomach, advocated by some. Well, because acid is stimulated by consumption of food, it is thought that taking live cultures on an empty stomach (mainly first thing in the morning) is ideal because there is less residual acid in the stomach. However, it is also important to note that there is a lag time (up to 30 minutes) between when food is eaten and when acid is released into the stomach
With a few exceptions, it’s best to take your live cultures supplements with a breakfast, as the food helps to buffer the effects of stomach acid; it may also help to facilitate the passage of the friendly bacteria through the stomach, and ensure that they are well mixed with the stomach contents as they pass into the small intestines.
This depends on why you are taking them: some people like to take specific strains at certain times, for example during pregnancy, when travelling abroad, or during the winter flu season. However, if you prefer general daily supplementation, then take your supplements every day. There is no current research to suggest the body becomes dependent on good bacteria, so long-term supplementation is also fine.

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

When choosing a live cultures supplement, remember that high strength does not always mean high quality.
Rather than looking at the number of billions, it is far more important to look at the good bacteria strains it contains. It is best to choose a supplement containing high-quality strains which have been used in gold standard clinical trials. High-quality supplements will typically contain the same number of billions used in the clinical trials; sometimes lower doses perform just as well as high doses1 so it is not worth paying extra for more billions than you need.
However, some people do better on a higher dose, and it is fine to experiment and increase the dose of any of our products; ultimately it all depends on your individual needs and responses to the supplement.
The human gut is home to roughly 100 trillion bacteria, so the dose contained in even our highest strength live cultures supplements (20-50 billion) is comparatively small. Many people take several of our supplements at the same time, depending on their individual needs and requirements. We’re all individual, however, so if you tend to be sensitive to new foods and supplements, sometimes it’s best to introduce them gradually. If you want to start with half a dose initially, then our live cultures capsules can be opened, and the contents taken alone.
Following the taxonomic updates published in April 2020, a reclassification has been proposed for the paracasei species, and the paracasei strain in 'For every day EXTRA Strength' may therefore now also be known as Lacticaseibacillus paracasei subsp. paracasei Lpc-37®, or still indeed as L. paracasei Lpc-37® for short.

Need help choosing a product?One of the best probiotic i've ever had. Also the support is very kind and helpful.
I’ve been using these probiotics for nearly a year and was introduced to them by a friend, Sarah who’s a nutritionist. After speaking to her about my issues with digesting starchy foods she recommended Extra Strength to try and it worked perfectly for me. I have been using them ever since and always buy the 90 day pack as they are better value for money, don’t run out so quickly and uses less plastic. I have continued to take one everyday as it has completely resolved my digestive issues and even have my family on probiotics too! Thank you Optibac for such a positive lifestyle change
My daughter has had a few food intolerances, and this product has really helped minimise the effects of certain foods on her tummy. On contacting customer support, they have advised me to also give her S Boulardii which I have found quite useful for her too.
