Where is ZOE available?

The ZOE membership is available for early access in the UK mainland, including Scottish Highlands and NI (excluding the Channel Islands - Guernsey, Jersey and the Isle of Man) and is expected to be on general release later in 2023.

We opted to bring the ZOE to the UK as soon as we possibly could, which means that some of the digital experience will still appear in American English and the database of foods isn't as comprehensive as we'd like yet.

Our early access members in the UK will get access to ZOE's cutting-edge at-home testing kit and the ZOE app. These first members will be asked for feedback about their experience to help ZOE get ready for general release in the UK.

You can Pre-order ZOE here to secure your kit and membership start date.

I am a ZOE COVID/Health Study Contributor. What is the relationship between ZOE membership and the COVID/Health Study?

Firstly, thank you so much for taking part in the ZOE COVID/Health Study! Thanks to you, we’ve been able to directly contribute to the fight against COVID-19 and chronic diseases in the UK and across the globe. We’re so proud of everything you’ve helped us achieve!

ZOE means life in Greek.

Founded by Jonathan, George and Tim in 2018. ZOE was designed to be something new. They bet that new technologies like machine learning and microbiome sequencing could enable scientific research at an unprecedented scale, allowing us to understand individual responses in the real world.

ZOE is a global brand that uses data-driven research to tackle global health issues and help optimise health for everyone. Through ZOE’s core research focus on the microbiome and gut health, we discovered that anyone can improve their health by understanding their unique biology.

The PREDICT 1 & 2 Studies were the largest nutritional studies of their kind, enabled by remote data-gathering through a mobile phone app. This research formed the scientific foundation of ZOE.

When the COVID pandemic hit, ZOE rapidly applied their predictive data expertise to study COVID-19 at scale. Through self-reported symptoms and test results, contributors built a picture of the pandemic playing out in real time. It enabled scientists to predict case numbers and locations, while also discovering unknown symptoms of the new disease. We’re incredibly proud of the work our team and our ZOE COVID Study contributors have been able to achieve.

The ZOE Health Study is an evolution of the ZOE COVID Study. Using the same approach, we hope to unlock the secrets of the immune system and understand how everyday behaviour can reduce the risk of chronic diseases, from cancer to dementia.

I have a medical condition. Is ZOE suitable for me?

We do not diagnose, prevent, or treat any diseases (including metabolic or inflammatory conditions). If you have any underlying health conditions you should consult your doctor before joining ZOE.

The ZOE membership is not appropriate for those with an eating disorder or a history of eating disorders.

Chronic conditions and diabetes

We do factor some conditions into our advice, including many common medications for diabetes (e.g. metformin) and heart disease (e.g. statins).

To access the blood sensor you'll also need to consent to take part in our study, which excludes chronic diseases like diabetes. Read more about our entry criteria here.

Gut issues

Unfortunately, if you have a gut disease (e.g. Crohn’s disease, ulcerative colitis, or celiac disease) then you are not eligible for the ZOE membership.

If you have a sensitive gut (e.g. irritable bowel syndrome) then you may join the programme. However, you should understand that our advice is for general wellness and is not specifically formulated for your condition. Some diet changes we recommend such as increasing fibre and diversifying your plant intake have been shown to trigger adverse responses in some people with a sensitive gut. Whilst we give advice that is suitable for most people, following our advice could make your condition worse. We are actively researching how we might be able to adjust our advice specifically for people living with irritable bowel syndrome.

Is ZOE FSA eligible?

Not at this moment, but it is an idea for the future.

What does the ZOE membership include?

Our membership is the first of its kind to combine microbiome analysis, blood testing, food logging and continuous blood sugar monitoring. This provides 360° metabolic analysis that can be conducted remotely within the comfort of your own home.

Here's what's included in the ZOE membership:

Gut microbiome test

Understand your gut microbiome health. Our simple at-home poo test is patent pending with the most advanced analysis on the market. Using deep shotgun sequencing, we can identify specific 'good' and 'bad' gut bugs that are linked to 'good' and 'bad' metabolic health.

Blood sugar & fat metabolism tests

Understand your unique metabolism. Simple tests (blood test, test meal, and optional blood sugar sensor) measure your blood sugar and blood fat levels after eating food. The specially formulated test meal has changed slightly over the years but remains true to the original recipe used in the ZOE PREDICT studies.

Your responses to food

6 weeks after testing, you'll get the test results of your microbiome and metabolic health and a ZOE analysis of what it means for your health.

Members app

Get access to the ZOE app where you'll learn your unique responses to any food, recipe or meal. Use the app to track your diet, get a motivating day score, and learn how to improve. You'll also get unlimited chat support with our ZOE Coaches to help you reach your goal.

Personalised program

Learn how to eat for your biology with a personalised week-by-week plan. We’ll guide and empower you to make better decisions daily. Over the months of your membership, these changes will be conditioned into long-term habits.

Our test kits alone cost over £1000. Because of our scale, we can make substantial savings that we pass on to our customers.

We are in the process of testing new pricing and memberships so we can continue to learn how to best serve our members. The total cost of the ZOE membership will depend on which pricing plan and optional add-ons you choose to purchase.

Gut health guidance

Discover how good your microbiome is and specific foods to help you boost the good microbes you are missing.

Can I buy the tests individually, without membership?

No, ZOE tests cannot be bought without a membership. The scientific insights from our tests are powerful, but it's the ZOE membership that turns them into long-lasting habits.

The app gives you access to your personalised ZOE Scores for any food or meal, access to our team of expert nutrition coaches and daily bite-sized lessons designed to help you reach your goals.

Taking the tests alone makes achieving long-term health goals harder for our members, so we do not recommend it.

ZOE Testing

What is the nutrition information of the cookies?

Your cookies were specifically designed by scientists to enable you to test your biological responses. The purpose of the cookies is to challenge your metabolism with high doses of fat and sugar over 6 hours. 

To be able to package the necessary amounts of nutrients in the challenge in a standardized way, we used cookies. We created specific recipes to understand your biology and recommend the best foods for you. 

  • The metabolic challenge: you'll receive 2 'breakfast' cookies. Nutritional information for these can be found under 'Breakfast Test Cookies' in the table below. 

  • The average meal: you'll receive two 'lunch' cookies. Nutritional information for these can be found under 'Lunch Test Cookies' in the table below.


Breakfast Test Cookie 

  • White chocolate chips (cocoa butter, cane sugar, tapioca starch, rice syrup solids, rice maltodextrin, organic vanilla and salt) 

  • Flour blend (brown rice flour, sweet rice flour, tapioca starch, cornstarch, potato starch, stabilizer (xanthan gum)) 

  • Palm oil 

  • Brown sugar 

  • Chickpea flour 

  • Tapioca starch 

  • Tapioca syrup 

  • Less than 2% of: water, vanilla bean extractives, salt

Lunch Test Cookie

How can I qualify for a blood sugar sensor?

To get a free blood sugar sensor with your test kit you must consent to our clinical study. The cost of the program does not include any study-related costs (including the blood sugar sensor) as ZOE covers these. To be eligible for the study you must meet the following criteria:

  • You are at least 18 years of age

  • You live in England, Scotland, Wales or Northern Ireland

  • You have a body mass index (BMI) of at least 16.5kg/m2

  • You are not pregnant

  • You have not had a heart attack (myocardial infarction), stroke/transient ischemic attack or major surgery in the last two months

  • You can safely eat our test cookies (See 'What is the nutrition information of the cookies?' above for the ingredient list)

  • If you are being treated for chronic medical conditions (including type 1 diabetes or type 2 diabetes), you have checked with your treating physician that this product is safe for you (note that to participate in the PREDICT 3 study you must not have been diagnosed with eating disorders, type 1 diabetes or type 2 diabetes)

I’m not sure about collecting my poo. Will it need to be stored in my fridge?

The poo test is easy to collect and comes with step-by-step instructions to help you. The sample goes into a solution that preserves it, so there is no need to store it in your fridge. Phew!

How does ZOE analyse my gut microbiome?

There's a variety of next-generation sequencing approaches for studying the human microbiome. We chose shotgun metagenomics as it is the most comprehensive approach at sampling the whole DNA content of a microbiome.

This technique can detect very low abundance members of the microbial community (i.e. those found in very small numbers) that may be missed using other methods and provides information about the metabolic processes and functions present within a microbial community.

You can learn more about how we analyse your gut microbiome here.

Are your test meals suitable for vegans or vegetarians?

As of September 2023, we have reformulated our previous muffin test meal into a cookie form that is now suitable for vegans and vegetarians. 

They are also free of all major allergens and alcohol but have been made in a facility that handles tree nuts, peanuts, wheat, and eggs.

The cookies are not certified gluten-free or kosher. 

If you received a test kit that contains muffins, please note that while our muffins do not contain gluten or dairy, they do contain egg. 

The muffins have been produced in a facility that also handles milk, egg, fish, shellfish, tree nuts, wheat, peanuts and soy. 

How long after ordering my test kit can I expect it to arrive?

When you pre-order your kit for a future month, we'll ship it to you during that month. Once it's shipped, it should be with you within 3-5 days. We'll let you know via email when your order's on its way and give you a tracking number to follow it.

Can I get retested to see if my results have changed by following the ZOE program?

Yes, we're bringing gut health retests to all ZOE members in the UK over the coming months, and to ZOE members in the US in 2024.

Why start with gut health? Our data shows that, when following the ZOE program, changes to the gut microbiome occur more quickly than improvements to blood fat or blood sugar control. Retesting for all health markers will follow in the future.

How much does the ZOE gut health retest cost?

The regular price is £199. Occasionally, we might have special offers available.

How can I purchase a gut health retest?

Active ZOE members who have received their results 4 months ago are eligible to retest and discover how their microbiome has changed.

Gut health retests are currently available, exclusively by invitation.

What can I expect in my gut health retest results?

Your retest results will be delivered in the app and include:

  • ZOE Microbiome Health Score

  • Good and bad bacteria

You’ll be able to compare these with your initial test results to see how your gut health has improved by following our dietary recommendations.

We’ll also update your Gut Boosters and Surpresors based on your latest gut bacteria and provide you with updated personalised ZOE scores.

Blood Sugar Sensor

Are there any health conditions that mean I can’t join the study and get a blood sugar sensor?

Yes - there are some criteria that mean you can’t join the study and therefore will be unable to access the blood sugar sensor (also known as a continuous glucose monitor or CGM):

  • Pregnancy

  • If you’ve had a heart attack (myocardial infarction) or stroke/transient ischemic attack in the last two months

  • If you’ve had major surgery in the last two months

  • If you cannot safely eat our test cookies (See 'Are your test meals suitable for vegans or vegetarians?' above for ingredient list)

  • If you’re being treated for chronic conditions including type 1 and type 2 diabetes

  • If you’re unable to fast for four hours

  • If you have a BMI of less than 16.5

Why do I have to join a study to have the blood sugar sensor?

To get a blood sugar sensor you must consent to our clinical study. There are no additional costs to you for having to do so. After purchasing a ZOE plan, you will be directed to a page where you are prompted to complete your order and consent to our study. To be eligible, you must meet the following criteria:

  • You are at least 18 years of age

  • You live in England, Scotland, Wales or Northern Ireland

  • You have a body mass index (BMI) of at least 16.5kg/m2

  • You are not pregnant

  • You have not had a heart attack (myocardial infarction), stroke/transient ischemic attack or major surgery in the last two month

  • You can safely eat our test cookies (See 'Are your test meals suitable for vegans or vegetarians?' above for the ingredient list)

  • If you are being treated for chronic medical conditions (including type 1 diabetes or type 2 diabetes), you have checked with your doctor that this product is safe for you (note that to participate in the PREDICT 3 study you must not have been diagnosed with eating disorders, type 1 diabetes or type 2 diabetes)

I have an old mobile phone - will it work with my blood sugar sensor?

The blood sugar sensor (also known as a continuous glucose monitor or CGM) is a blood sugar monitoring device manufactured by Abbott.

To collect data, it connects to an app on your mobile phone, LibreLink, via a form of wireless technology called near field communication, NFC. As such, it can only work with newer devices that have this function.

App compatibility

To check your device meets requirements, please download and attempt to install it as follows:

Device compatibility


  • The sensor is only compatible with an iPhone 7 or later / iPhone SE (2nd gen)

  • Your phone will need to run iOS 15 or later

  • We can't support iPads


  • You’ll need Android 8 or later

  • The oldest devices we support are: Galaxy Note 8, S7 Edge, S8, S8+, S9, S10; Google Pixel, Pixel 2, Pixel 2 XL, Pixel 3, Pixel 3 XL, Pixel 4, Pixel 4 XL; LG Nexus 5X

  • You need to be able to install apps from the Google Play Store - some recent Huawei phones cannot

Can I shower or go swimming with my blood sugar sensor?

You can shower or bathe while wearing the blood sugar sensor. However, it shouldn’t be taken below a depth of 1 metre (3ft) in water or submerged in water for more than 30 minutes as this could break or deactivate it.

That’s why we recommend that you avoid swimming or using saunas or steam rooms until you’ve finished your test.

How do I apply the sensor? Does it hurt?

The sensor comes provided with a plastic applicator. Cleaning the skin with the provided alcohol wipe, you place this firmly on the skin. With a firm ‘stamping’ motion, it gets applied. Some people may feel a slight pinching sensation, but this goes away soon after and the sensor should be painless to wear.

We recommend placing it on the back of your arm to avoid knocking the sensor and potentially dislodging it. We’ll also provide you with a latex-free sticker to cover the sensor, to keep it extra safe!

Can I exercise while wearing the sensor?

Absolutely! We actually encourage it to see how exercise affects your sugar response. If you play contact sports, plan to wear your sensor when you’re not playing a game, or position it somewhere that is unlikely to get hit.

Do I need to pay for the sensor separately?

No. ZOE covers any specific study-related costs, so you do not pay extra for the sensor.

How long do I have to wear the sensor for?

The sensor lasts for approximately two weeks. We’ll gather the crucial information - your response to the test cookies - over a few days. For the remainder of the time, you’re free to experiment with different foods to get visual real-time feedback on how your body responds to sugar. You can also explore how different interventions can minimise the detrimental impact of sugar on your body.

Will I be able to purchase a new sensor once this one stops working?

No. Sensors are only available as part of the test kit and as such are limited to one per person.

How many sensors will I receive?

You will receive one LibreLink sensor. This sensor is worn and collects data for up to two weeks. We are able to get all we need for your results from this time window.

Results & Programme

How long can I expect to wait after testing to receive results?

To get your results you will first need to complete your tests at home and return your samples in the package provided. From there it currently takes about 6 weeks for our labs to process your samples. You will then receive an email as soon as your insight reports are ready to view.

In some cases, results will take longer to process due to retesting. If you need to retest due to issues with any of your samples, we will contact you via email immediately. From the point of retesting, you can expect to receive your results within 4-6 weeks.

Can I access a sample report?

No, we don't have sample reports that we can share.

Here's what you can expect to receive:

  • A dietary inflammation profile (blood sugar & blood fat control), scored from 0-100, 'Bad' to 'Excellent'

  • An introduction to our food scores

  • Personalised food insights for your meals logged during your testing week

  • The abundance of 15 "good" and "bad" microbes from your gut health sample

How does ZOE define the 15 'good' and 15 'bad' bugs?

This is based on the microbiome research we have done in which we did an analysis of correlation of the health of the PREDICT participants and the bugs that were present in their microbiome. For the PREDICT participants, we had data on various health markers and on what bugs were present. We found the 15 top bugs associated with good health markers, and the 15 bugs associated with bad health markers.

You can learn more about this research here.


Do I need a smartphone to access ZOE?

Yes. The ZOE app is currently available on both iOS (iPhone or iPad with iOS version 15 or later) and Android devices (Samsung, LG, Motorola etc. with Android 8.0 or later).

You'll also need to download and use the Abbott FreeStyle LibreLink app if you've opted-in to our study and will be using the blood sugar sensor.


In order to be able to opt-in to the study, your phone must be compatible with the Abbott FreeStyle LibreLink app.

Device requirements:

  • iPhone iOS 15 or later and an iPhone 7 or newer. / iPhone SE (2nd gen). We can't support iPads

  • Android 8.0 or later. The oldest Android devices supported are: Galaxy Note 8, S7 Edge, S8, S8+, S9, S10; Google Pixel, Pixel 2, Pixel 2 XL, Pixel 3, Pixel 3 XL, Pixel 4, Pixel 4 XL; LG Nexus 5X. You'll also need to check you can install apps from the Google Play Store (some recent Huawei phones cannot)

Is my data secure? What is your privacy policy?

We take data security and your privacy seriously and your information will be stored securely. Our full privacy policy can be found here.


What can ZOE coaches help me with?
