You can find some quick answers in the FAQ section below.

How is Symprove made?

Symprove is made in a controlled environment through a series of carefully controlled stages. First we boil specially selected grain to create a wort. The wort is purified and sterilised and following this, the temperature is controlled in sterilised vats and the four strains of bacteria are carefully introduced. The live bacteria begin to divide and once the required levels are reached, the process is halted and Symprove is ready for bottling once it’s been tested by an independent laboratory. Throughout every stage, the bacteria are carefully nurtured as they are living organisms. The bacteria we use are high purity laboratory cultures which are unique to Symprove.

Is Symprove a prebiotic or probiotic?

Symprove is a food supplement which contains live bacteria in a barley extract. The bacteria may be considered probiotics, and the barley extract a prebiotic. However, the use of both these terms is not permissible in commercial communications under European food law.

Is there any research into Symprove?

Symprove has a strong Research & Development Programme and is constantly improving its products. We are researching two main areas. Firstly, the effectiveness of the delivery system, where we work extensively with independent laboratories and Healthcare Professionals to make sure our delivery system is as good as it can possibly be. In fact, breakthrough independent research by University College London (UCL) shows that Symprove met all three challenges to be able to arrive, survive, thrive and colonise in the gut.

Secondly, for over 10 years, Symprove have invested heavily into research with leading independent Health professionals to demonstrate the effectiveness of Symprove. If you're a healthcare professional, you can visit our dedicated page:

What health claims can Symprove make?

Regulatory law means that probiotics are categorised as food products and cannot make health claims. In addition, it is now no longer permissible to use the word probiotics in consumer marketing materials. Many people believe that taking products containing live bacteria are important tools for a healthy lifestyle.

Please see our Trustpilot reviews to read other people’s experiences.

What is Symprove?

Symprove is a water-based formulation that contains four unique strains of live activated bacteria. Because of this unique formulation Symprove will not trigger digestion, meaning the bacteria are able to:

Arrive to the gut unharmed and in full strength

Survive the harsh acidic environment of the stomach

Thrive in the gut to colonise successfully

Symprove helps to support the gut microbiome and balance gut bacteria.

What is the 12 week programme?

Symprove comes in packs of four x 500ml bottles. Each single bottle will last you 7-8 days on the 12 week programme. Your 12 week programme will consist of three four-packs. We want you to use Symprove for at least 12 weeks as it can take time for dietary changes to take effect. British Society of Gastroenterology guidelines also recommend 12 weeks when trying bacteria-based supplements.

Each morning, on an empty stomach, take a 70ml dose using the cup provided in the box, and leave it a minimum of ten minutes before eating and drinking anything.

If you have purchased all 12 bottles in one go, please ensure you start your 12 week programme straightaway because of the shelf-life of the product.

Who makes Symprove?

Symprove is made by Symprove Holdings Ltd. in the UK. The Founding Team have over 25 years’ experience of making live culture products. All the ingredients in Symprove are sourced and produced in Great Britain. 

Why does your microbiome matter?

How is Symprove delivered?

We offer free next working day delivery by courier on all four-pack purchases if you order by 4pm.

Delivery days are Monday to Friday. You will receive tracking details from the courier together with a 1 hour time slot, on the day of delivery by email or text. The courier offers you full control of the parcel, including the ability to deliver to an alternative address, or requesting the parcel be left safely on your property.

What does Symprove taste like?

Symprove is available in 2 flavours


The original flavour has a malty, grain-like taste, sharper and earthier than the mango. With acidic tones.

Mango and Passionfruit

The mango and passionfruit has a fruity sweetness and is a less complex flavour.  There’s a slight underlying tartness.


Is your packaging recyclable?

We are committed to reducing our impact on the environment through our packaging. We have recently upgraded our bottles to PET plastic (the world’s most recycled plastic) to ensure that they are more widely recycled; our outer packaging is also fully recyclable.

Can I overdose?

As Symprove is classed as a food supplement opposed to a medication you cannot overdose however we advise for an adult to take just one full 70ml dose daily (full measuring cup). We have only ever completed any clinical trials on the full 70ml dose therefore we have no reason to advise you to take any more than this. For children the dosage differs slightly, we would advise 1ml per kilo of body weight (20kilo = 20ml dose / 35kilo = 35ml dose etc) the only reason we advise the lower dosage is to give their microbiome a little more time to get used to the product as they are still developing.

Can I still take my other supplements?

Yes. Symprove is fine to take with other supplements. 

Can I take Symprove and alcohol?

Alcohol can have a strong negative effect on your gut bacteria. We recommend alcohol is avoided for a few hours after taking Symprove.

Can I travel with Symprove?

Many customers travel successfully with Symprove and we ship it all over the world. If you can put it in the refrigerator when you get to your destination that’s great, but if not just try and keep it in a cool place and it should be ok.

Can Symprove survive at ambient temperatures?

The bacteria in Symprove easily survive in ambient temperatures. Once you open a bottle of Symprove, please pop in the fridge and be sure to consume within 10 days of opening. If you are travelling abroad with Symprove, it can go in the hold of an aeroplane without any problems. If your destination is warm/hot and you do not have access to a fridge, we recommend you fill a sink with cold water and keep your Symprove in it to keep cool. Remember to change the water regularly to try and keep it as cool as you can. We have many flight attendants who take Symprove and this was a top tip from them!

Does Symprove need to be kept in the refrigerator?

Once you open a bottle of Symprove, please pop in the fridge and be sure to consume within 10 days of opening.

How long do I need to take Symprove?

In order to keep your gut bacteria in balance once the 12 week programme is complete, we recommend that you continue to take Symprove – why not consider a subscription?

How much Symprove should I take?

Simply fill the small cup (70ml) provided with your bottle of Symprove and take every morning on an empty stomach. Wait 10 minutes (ideally) before eating or drinking then continue with your day as usual. Each cup contains about 10 billion live colony forming units.

How should I look after Symprove?

Before opening, Symprove should be stored in a cool dark place.

Once opened, keep in the fridge and consume within 10 days of opening.

Do not freeze or heat as this will kill the bacteria.

Should I take Symprove during/following antibiotics?

Yes, it’s always helpful to top up your gut during or after antibiotic treatment to maintain balance in the gut. Whilst antibiotics usually help to get on top of illness, they can also destroy the ‘beneficial’ bacteria in the gut at the same time.

We recommend that you take Symprove at a different time to your antibiotics if possible – remember that ideally you should take Symprove a minimum of 10 minutes before eating or drinking to allow it to pass through the stomach to successfully arrive, survive and thrive in the gut.

Should I take Symprove with food?

We recommend you take Symprove first thing in the morning, on an empty stomach, before breakfast. Ideally, you should wait a minimum of 10 minutes before eating and drinking to allow Symprove the best chance of reaching your gut quickly and begin colonising. If you do eat immediately afterwards or drink Symprove with food, it won’t do you any harm, but it may slow down the delivery of Symprove. If you forget to take Symprove first thing and have eaten, allow two hours after eating and then take Symprove.

What happens if I miss a dose?

The recommended dose of 70ml a day is to ensure that colonisation of the gut is maintained by the bacteria within Symprove. Each person has a different gut microbiome and may be affected differently by missing a dose or stopping Symprove. Whilst there may be no obvious change to your body, we advise that you return to a daily recommended use as soon as possible.

What is the shelf life for Symprove and how should it be stored?

Symprove is bottled as a live culture but it can be stored at room temperature in a cool, dry place. The shelf-life is three to four months (please read the best before date which is printed on the bottle). Once opened, keep refrigerated but do not freeze or heat as this will kill the bacteria.

Are there any contraindications?

The majority of our customers do not receive any contraindications from Symprove however some customers do experience slight side effects at the beginning of their journey. Side effects will be showing you that the bacteria has managed to get to where it needs to be and it is getting to work however if the gut is not used to receiving this it can be a bit of a shock which is what can bring the effects on for a short period of time. If we hear of anything it will usually be a slight loosening of stools or constipation. All side effects should gradually ease off the more your gut gets used to the bacteria you are introducing daily. Please also note that we are a customer care team therefore you are more than welcome to contact us to discuss your journey.

Can Symprove be used whilst breast-feeding/pregnant or if I am immune compromised?

Symprove is a safe food supplement. If you are on medication please check your medicine leaflet for any foods to avoid. However, if you are unsure, please speak to your healthcare practitioner.


Symprove is a food supplement that contains live and activated bacteria; it does not contain any of the food ingredients recommended for avoidance during pregnancy and breast-feeding. However, as with any significant dietary changes during pregnancy and breastfeeding, we would always recommend that you check with your healthcare professional first.

For people who are immune compromised, we would recommend you take a copy of the label and discuss suitability with your healthcare professional.

Can you give Symprove to children?

As Symprove is a natural food supplement, it is suitable for children at the parent/carer's discretion. A dose of 1ml per kg of weight should be used.

Does it work for everyone?

The majority of our customers report a benefit when used with a balanced diet and lifestyle.

Does Symprove have any side effects?

It is important to remember that in a very few cases, during the early days of taking Symprove, some people experience loosening of the stools as their body adjusts to the new bacteria. This is perfectly normal and should soon settle (continue to take Symprove every day even if this happens).

Does Symprove work with the FODMAP diet?

Many clinicians and customers have used Symprove alongside the FODMAP diet. We would recommend talking to a healthcare professional regarding the two working together. If you want to know more about FODMAP diets, please consult your healthcare professional, dietitian or nutritional therapist. 

Is Symprove a natural product?

Most of the ingredients in Symprove are naturally occurring, from the barley to the beneficial bacteria that make it their home. The only additional ingredients are vitamin C, potassium sorbate and trisodium citrate which are found in everyday foods, we also use natural flavours for the Mango & Passion Fruit flavour, having carefully tested the stability of the flavoured product before release. 

Are there any allergens in the product?

Symprove is non-dairy, gluten-free, and vegan friendly. It does not contain any animal products. To check whether it is suitable for you please make sure you read the ingredients list before you use our product.

Is Symprove dairy-free?

Symprove does not contain any dairy.

Is Symprove gluten-free?

Symprove is gluten-free according to the Codex standard of <20ppm. Whilst barley, which contains a form of gluten, is used to make the liquid in which we grow the Symprove bacteria, the production process is carefully controlled to limit the release of gluten from the barley, and the barley grain is not included in the finished product. Compliance with the Codex standard for gluten free is confirmed with regular testing of batches of our finished Symprove products.

Is Symprove suitable for vegans?

 Yes.  Symprove does not contain any animal products in the formulation so it is suitable for vegans.

What are the active ingredients in Symprove?

The active ingredients in Symprove are four live, activated lactic acid bacteria species:

- Lactobacillus rhamnosus

- Enterococcus faecium

- Lactobacillus acidophilus

- Lactobacillus plantarum

All four species of bacteria have a history of safe use in food.

What ingredients are in Symprove?


Ingredients: Water, extract of germinated barley, live activated cultures of: L. rhamnosus NCIMB 30174, E. faecium NCIMB 30176, L. plantarum NCIMB 30173, L. acidophilus NCIMB 30175; acidity regulators: ascorbic acid, trisodium citrate; preservative: potassium sorbate.


Ingredients: Water, extract of germinated barley, live activated cultures of: L. rhamnosus NCIMB 30174, E. faecium NCIMB 30176, L. plantarum NCIMB 30173, L. acidophilus NCIMB 30175; acidity regulators: ascorbic acid, trisodium citrate; preservative: potassium sorbate; natural flavourings.

We always look for the best quality ingredients for use in Symprove and source these from reputable suppliers.  Whilst we do aim to source locally, where possible, this is dependent on the availability of ingredients which meet our high quality standards.  Our bacteria are all produced in the UK.

Who should drink Symprove?

Anyone who wants to support their gut microbiome. Symprove is totally different to any other multi-strain bacteria product due to the unique way that it delivers live, activated bacteria. It is important to understand, however, that Symprove is not a medicine but a liquid food supplement and should be taken in addition to a balanced diet. If you are in any doubt about whether to include a food supplement in your diet, you should discuss this with your doctor or other appropriate healthcare professional.

Symprove is also an ISO9001:2015 certified company. On top of this, our products are constantly under scrutiny within our Research & Development Programme.

What difference might I see over the 12 weeks?

A minority of people report some ups and downs as their bodies adjust to the Symprove bacteria.  This is perfectly normal so don’t be alarmed and continue to take Symprove daily.

Most people report a positive feeling within the first few weeks, although it can take longer.

It’s important to take Symprove for the full 12 weeks to give your body time to adjust to the dietary change. British Society of Gastroenterology guidelines also recommend 12 weeks when trying bacteria-based supplements.

In the latter part of the 12 week programme, our customers generally report that their experience settles as routine is established and they become accustomed to the Symprove bacteria.

From an independent trial on Symprove it was found that 12 weeks was an optimal period for change.
