Frequently Asked Questions


What are friendly bacteria and why do I need them?  

Friendly bacteria are found naturally occurring in your digestive system and makeup part of your gut microbiome. This gut microbiome has several roles in your body including;

      • Helping with the production of vitamins B and K
      • Playing an important role in the development of our immune system
      • Digesting fibre that has not been broken down by the stomach or small and large intestines
      • Helping us combat and overcome harmful microorganisms
      • Supporting the function of our digestive system

This delicate ecosystem can be disturbed by several factors including diet, lifestyle, alcohol and stress. Our range of friendly bacteria supplements delivers live strains of bacteria to help balance your gut microbiome, helping to keep you and your microbes happy and healthy.

What are natural fibres?

Natural fibres are non-digestible fibres which act as a food source for our friendly bacteria, helping them grow and thrive in our gut microbiome. Natural fibres can be found in some foods, including asparagus, garlic, onion, Jerusalem artichoke, banana, barley and rye.

Do I need to take both friendly bacteria and natural fibres?

You do not need to take natural fibres alongside friendly bacteria in order for the friendly bacteria to be effective.
However, we believe it is important to not only provide our gut with friendly bacteria but also the food they need to grow and thrive in our gut microbiome.

You can find several types of natural fibres in our products including fructo-oligosaccharides, soy fibre and gum acacia.

What is Lactobacillus?

Lactobacillus is a genus of bacteria. This group contains a large number of different types of bacteria that produce lactic acid.

Within this genus there are several bacterial species which are naturally present in the human gut, these include Lactobacillus rhamnosus and Lactobacillus acidophillus. They can also be found in fermented foods like yoghurt.

Bacteria from this genus have been featured in countless clinical trials. For example, Lactabacillus rhamnosus GG is one of the most clinically researched strain of friendly bacteria and can be found in one of our products, Probio7 Kidskalm.

What is Bifidobacterium?

Bifidobacterium is a genus of bacteria.

Within this genus there are several bacterial species which are naturally present in the large intestine, these include Bifidobacterium bifidum, Bifidobacterium infantis and Bifidobacterium breve, to name a few.

Species of Bifidobacterium are dominant in healthy infants. Probio7 Bifikalm, which has been specifically formulated for infants 2 months + contains a species of Bifidobacterium that is found naturally in healthy infants gut microbiome.

What is Saccharomyces boulardii?

Saccharomyces boulardii is a friendly strain of yeast. It has been used for the last 30 years to support the gastrointestinal tract. Saccharomyces boulardii has been well-researched and has been used safely for many years.

What is CFU?

CFU stands for colony-forming unit. This term is used to describe the number of viable bacterial cells in a sample.
Viable bacteria is defined as capable of surviving or living successfully, especially under particular environmental conditions.

For example, if a friendly bacteria supplement says it contains 10 billion CFU per capsule, this means it contains 10 billion live friendly bacteria per capsule.

Where do the bacteria come from?

The majority of our strains were initially isolated from the digestive tract of healthy humans and others were extracted from dairy sources, such as yoghurt.

This does not mean that the friendly bacteria in our supplements have been taking directly from humans.
The original strains that were initially isolated from a human digestive tract are stored in friendly bacteria 'banks' and the bacteria are cultured by scientists in laboratories to make identical copies that are then used in our supplements.

Our Products

Is Probio7 guaranteed until the best before date?

Yes, our strains of friendly bacteria have been freeze dried making them shelf stable. This means that our products do not need to be refrigerated upon purchase.

In order to ensure that the bacteria are viable until the end of their shelf life, we recommend storing them in a cool, dry place out of direct sunlight.

I am vegan, can I take Probio7?

Several of our products are suitable for vegans and have been approved by the Vegan Society. Our vegan products are clearly marked by the Vegan Society logo (as seen as below)

If you have a certain dietary requirement and you want to know if Probio7 is suitable for you, please contact or call +44 (0) 2086486777.

Can I take Probio7 if I'm pregnant?

Probio7 is formulated using natural ingredients which are generally considered safe during pregnancy and breastfeeding. However, it is always preferable to seek medical advice when taking any food supplements during pregnancy and when breastfeeding.

I have an allergy, can I take Probio7?

Some of our products contain common allergens, these are highlighted in the ingredients. To find the list of common allergens in our product, please see the list below.

If you have an allergen and want to know if Probio7 is safe for you, please contact or call +44 (0) 2086486777.

Is Probio7 suitable to taking alongside antibiotics?

Yes, Probio7 products are safe to use alongside antibiotics. If you are due to start a course of antibiotics, we recommend taking Probio7 Restore, to help replenish your gut microbiome during and after antibiotic treatment.

Wait 2-4 hours after taking your antibiotics before taking your Probio7 supplement, with food.

Can I take Probio7 alongside other medication?

Friendly bacteria supplements are generally safe to take alongside other medication. However, if you are taking medication we would advise consulting your GP before taking Probio7.

Is Probio7 suitable for children?

Probio7 supplements are safe for children from 2 months+.

Children develop their microbiome in the womb and throughout early childhood. It’s thought that an unhealthy microbiome in the early stages of life may be responsible for some adult health conditions. We recommend Probio7 Bifikalm for infants aged 2 months +. For older children (aged 12 months to early teens) we recommend Probio7 Kidskalm. These products contain friendly bacteria strains specifically formulated to promote and maintain a healthy balance in the gut flora in infants and children.

Can I take Probio7 supplements long term?

Several of our Probio7 supplements have been formulated for daily, long term consumption. This is recommended to maintain a diverse gut flora. On the other hand, some of our products may be used at a specific time for example, when travelling abroad.

If you unsure how long you should take a Probio7 product for, get in touch with us at or call +44 (0) 2086486777.

I am severely immunosuppressed. Why can't I take friendly bacteria?

Patients who are immunosuppressed do not have the ability to mount an immune response to microbes that they come in contact with. Microbes, even those considered beneficial, can sometimes cross the gut barrier and grow in the blood or internal organs. Growth in these areas can cause septicemia, myo-endocarditis, or pancreatitis. Since there is currently insufficient clinical evidence around this area, the risk is thought to be too high to recommend friendly bacteria supplements for individuals who are immunocompromised.

If you are unsure whether friendly bacteria supplements are safe for you, contact us at or call +44 (0) 2086486777. Or, visit your GP.

What if I don’t like swallowing capsules?

Not a problem! Our capsules can either be swallowed whole or pulled apart and sprinkled over cold food or mixed in with a cold drink.

The capsules cannot be sprinkled onto hot food as this can affect the stability of the bacteria and may prevent all the bacteria reaching your digestive system alive. We recommend pulling the capsules apart and sprinkling it over some granola and yogurt or mixing it into a morning smoothie!

The bioavailability of our products will not be affected when mixed with food. Many foods have beneficial bacteria growing in them naturally including yogurt, kefir and sauerkraut which shows that bacteria are able to survive on food.

When is the best time to take Probio7?

The best time to take Probio7 is in the morning, with breakfast.

Can I take two Probio7 products at the same time?

Yes, you can. There is no limit to the number of bacteria you can consume as they are a natural part of our digestive system. It is almost impossible to overdose on friendly bacteria.

Taking two different products from the Probio7 range means you can get a range of benefits from several different friendly bacteria species.

However, it is important to bear in mind that if you have never taken a friendly bacteria supplement before or you suddenly increase your dose, you may notice some temporary changes in the state of your gut microbiome which may result in more flatulence or bloating. This is nothing to worry about – this shows that the bacteria are working and should subside in a few days!

How do I store Probio7?

Our products do not need to be refrigerated and are shelf stable for at least 2 years. To get the most out of our products leave them somewhere cool, dry and away from direct sunlight.

When will I see an effect?

In order to see the beneficial effects of Probio7 we recommend taking it for at least 4 weeks. However, if you are not happy with the effect of Probio7 please email our nutritionist or book a call through this link to discuss alternatives.

Which product should I take if I have IBS?

People suffering from Irritable Bowel Syndrome (IBS) may be recommended friendly bacteria supplements to help manage their symptoms. However, as IBS can vary significantly between individuals whilst product might work well for one person, this isn't guaranteed to work well for someone else and you may have to try several different products until you find one that works for you.

If you would like to discuss different supplements for your IBS with a nutritionist then please email or book a call through this link.

Why do I need different strains of probiotics?

Friendly bacteria supplements are characterised by their genus, species and strain code and their properties are strain specific.

To put it into perspective, a species is a genetic concept. It indicates the same origin but not the same properties. All dogs fall under the species Canis familiaris however, dogs within that same species have very different properties. The strain code is like a dog’s breed, it indicates the same properties.

Some strains are known to be beneficial for certain properties. For example, the well-known strain Lactobacillus rhamnosus GG has been tested in several clinical studies to help alleviate diarrhoea symptoms caused by a number of factors including, antibiotic-associated diarrhoea and travellers’ diarrhoea.

We include a range of different strains of friendly bacteria in our products, so you are able to get a number of benefits from one capsule. Additionally, our products have been formulated to suit the specific need or target age.

For example, Probio7 Bifikalm has been formulated for infants 2 months+ and contains two strains of friendly bacteria that are naturally found in an infant’s gut microbiome.

How many billion of live cultures is best suited for me?

Unfortunately, this is not a simple one-word answer! The number of live cultures suited varies on the individual. It is also not just about numbers, the bacteria strains are also very important.

We all have a unique gut microbiome, it is as personal as a fingerprint! Therefore, it is important you find a product that is right for you. You may have to try several different friendly bacteria supplements before you find the best one for you and your gut microbiome.

Our range of products vary from 1 billion to 100 billion bacteria per capsule! Each product we have has been formulated to suit a specific need or target age.

If you are unsure what product is right for you, take our Probio7 Consultation – a 5 minute free online questionnaire about your diet and lifestyle to help recommend a suitable Probio7 product. To take the consultation, click here.

Do Probio7 strains reach the gut alive?

All of our strains of friendly bacteria have been tested in-vitro (outside of the body, in test tubes) to survive the harshest of conditions to ensure they reach the digestive system alive. One of the biggest challenges for bacteria supplements is surviving the stomach acid. Our strains have been tested to survive this acidity. Once the bacteria reach the digestive system they become activated and can start carrying out their number of beneficial properties.

Our strains of friendly bacteria are very hardy, and they do not need to be consumed within the capsule in order to reach the digestive system alive. This is why you can pull the capsule apart and sprinkle the contents over food or drink and why some of our products come in an easy to use sachet or suspended in oil.

We also recommend taking our supplements in the morning with breakfast, when our stomach acid is at its lowest. This further ensures all the bacterial strains arrive in the digestive system alive.
