ZOE Review: Do You Really Need a Microbiome Test to Eat Better?

Zoe is a nutrition company that offers personalized nutrition services based on your biological responses. The brand also provides an app to log meals and receive daily nutrition scores based on your test results.

Zoe also includes access to personalized meal suggestions and nutrition guidance, aiming to support you in making informed dietary decisions.

In this review, you will learn about Zoe’s story, its science-based approach, and how it may help you take charge of your nutrition. We will look at the types of products and services Zoe offers and share what makes the brand different from similar brands present in the wellness space.

About Zoe

Zoe claims to use science-backed testing and data to help you understand how food uniquely affects your body. The brand’s offering includes an at-home test kit that analyzes your gut microbiome, blood sugar, and blood fat responses. These tests aim to provide insight into how your body processes different foods rather than generic advice.

ZOE’s approach is based on large-scale studies like PREDICT and BIOME. The company uses results from its clinical trials to deliver tailored recommendations through an app. After completing the tests, you receive a personalized program that includes food scores, meal plans, and educational content designed to guide your daily nutrition.

Instead of counting calories, the app helps you evaluate food quality through real-time scores based on your specific biology. The platform also combines artificial intelligence to personalize food recommendations, helping you make more informed decisions about what to eat.

As per the official website, Zoe also offers MenoScale, which may help you better understand the intensity and impact of your menopause symptoms.

Zoe Offerings

1. At-home testing kit + membership

   Zoe offers an at-home testing kit, “Gut Health Test,” and a membership that may help you analyze how your body responds to food. After signing up, you receive a kit with materials to collect small blood and stool samples. Instructions and step-by-step guides are included to help you complete the process without visiting a clinic or lab.

   The blood samples are used to measure both short-term and long-term metabolic responses, while the stool sample is analyzed to assess the composition of your gut microbiome, microorganisms in the digestive tract that influence various aspects of health.

   Once the samples are processed, Zoe’s labs evaluate three main areas. First, your blood sugar response is measured to assess how glucose levels rise and fall after eating, offering insight into energy management and blood sugar regulation. Then, blood fat response is analyzed to determine how efficiently your body clears fats from the bloodstream, which is relevant to heart health and inflammation risk. The microbiome analysis is then done to identify the types of microbes present, which can relate to digestion, immune function, and other fitness outcomes.

   The results are delivered through the Zoe app, which presents personalized scores and recommendations. Food scores indicate how well certain meals align with your biological responses. The app also provides insights related to blood sugar, lipid response, gut health, and metabolic function.

   Taking Zoe membership can give you access to these features, along with tracking tools, updates, and additional resources such as expert content and meal suggestions to help you apply the findings to your daily routine.

2. Menoscale

   Zoe has developed the Menoscale calculator to help you quantify menopause and perimenopause symptoms. The tool uses 20 questions to generate a score out of 100, measuring both the frequency and impact of symptoms.

   The score can be tracked over time to assess how symptoms change in response to dietary adjustments. This tool is part of Zoe’s broader program, which also includes food scores and metabolic insights based on your test results.

   After completing the at-home tests, you gain access to Zoe’s app. The app offers multiple ways to log meals, searching a food database, scanning barcodes, or importing recipes.

   Each meal generates a personalised score that reflects its potential impact on blood sugar, blood fat, and gut microbiome health. These scores are based on a combination of personal test results and data from Zoe’s PREDICT studies. The app by Zoe also includes weekly progress summaries, visual trend charts, and meal planning tools.

3. Daily30+

   According to the official website, Daily30+ is a wholefood formula that may support your gut health by increasing daily intake of plant-based fiber. It also includes fruits and vegetables, mushrooms, herbs, seeds, nuts, legumes, whole grains, and seaweed.

   The formula features six different seeds, including hemp seed, pumpkin seed, flaxseed, sunflower seed, grape seed, and chia seed, which provide plant-based protein, healthy fats, and minerals. For example, flaxseed and chia seed provide omega-3 fatty acids and fiber that may support digestion and heart health, while pumpkin and sunflower seeds supply magnesium, zinc, and vitamin E to boost immune health and act as antioxidants.

   Hemp seed adds further protein and healthy fats important for muscle and cardiovascular function, and grape seed offers additional antioxidants to protect cells from oxidative stress.

   Daily30+ also contains almonds, hazelnuts, and walnuts that may also provide healthy fats and antioxidants.

   Almonds provide calcium, which is essential for maintaining strong bones. Hazelnuts contain nutrients that could benefit brain function, potentially aiding cognitive performance. Walnuts have omega-3 fatty acids, which are known to support both heart health and brain function.

   Daily30+ also contains two legumes, including lentil flakes. These legumes offer complex carbohydrates that may help provide sustained energy over time. They also contribute plant-based protein, which can help you feel fuller for longer periods, supporting appetite control.

   Daily30+ is said to be vegan, gluten-free, and intended for integration into daily meals rather than being consumed on its own with water. The powder has a nutty, savoury flavour due to the mix of herbs, mushrooms, pulses, and seeds. It can be sprinkled on yoghurt, hummus, soups, salads, grilled dishes, or toast.

Zoe Advantages

1. AI-Powered Meal Logging App

   ZOE offers a structured program that combines at-home testing with app-based tracking to deliver personalized nutrition insights based on your biology. This AI-driven app approach of the brand helps you interpret results from your gut microbiome, blood sugar, and blood fat tests to generate diet recommendations. ZOE allows you to log meals using a detailed food database in its app, with portion sizes measured using the food scale provided in your test kit. This detailed logging supports ZOE’s emphasis on personalized tracking and helps ensure the recommendations are based on accurate food intake data. The brand’s “Describe My Meal” feature lets you log meals by describing them in plain language. This reduces the friction of food tracking and improves your adherence to the program. This integration may help you understand how your body responds to food and use that information to make informed dietary choices.

2. Maintains Strong Privacy

   ZOE requires you to submit biological samples, including blood and stool, to generate personalized nutrition insights. To support this, ZOE collects health-related data through at-home testing and claims to manage it under strict privacy protocols. All sample collection happens privately at home, which limits external handling and allows you to engage with the program without visiting a clinic.

   ZOE states that it complies with key privacy regulations, including the GDPR for users in the UK and EU, and HIPAA-aligned practices in the U.S. This means the data collected, such as gut microbiome profiles, blood fat responses, and other health metrics, is stored securely and processed for specific, stated purposes. The company explains its practices through accessible privacy documentation, allowing you to review how its information is handled within the ZOE ecosystem.

Zoe Limitations

1. Unresolved Billing and Unauthorized Charges

   According to complaints reported by the Better Business Bureau (BBB), several users have experienced challenges with ZOE’s delivery, subscription management, and customer support. For example, one user reported ordering the Daily30+ supplement but never received the product. Despite multiple follow-ups, the customer was met with delayed, automated responses and confusing instructions for canceling the subscription. Attempts to cancel through the website and app led to login loops, making it difficult to stop future charges.

   When the company finally responded, they revealed the product had been recalled due to contamination with stones and metal fragments, information that was not proactively shared.

   In another case, a user canceled their membership but continued to be charged for several months afterward. Even though they received confirmation of cancellation, charges continued. When the user disputed the charges with their credit card company, ZOE reportedly did not respond to the issuer’s inquiries, which resulted in additional unwanted renewal charges.

   These examples, as detailed by the BBB, highlight recurring problems in ZOE’s subscription system, delays in customer communication, and limited support escalation processes, particularly when you try to cancel your subscription or request a refund.

2. Access Is Linked Exclusively To Membership

   ZOE provides testing kits and personalized nutrition insights that are only available through an active membership subscription, costing $393.96 for four months, which means you cannot purchase or use the tests as standalone products. While the scientific data from their at-home gut health, blood sugar, and blood fat tests are valuable, ZOE emphasizes that it is the ongoing subscription, delivered via their app, that turns these insights into actionable, lasting habits. This means you must maintain a paid membership to continuously access your personalized food scores, meal plans, coaching tools, and educational content.

   This subscription-based model can limit your flexibility and lock you into continuous payments to benefit from the program. If you’re looking for a one-off test or prefer occasional usage, ZOE’s structure may not align with your needs.

   Ombre is focused on microbiome-specific service with actionable probiotic recommendations and a streamlined experience. On the other hand, Zoe delivers a broader, scientifically grounded program that connects your gut health to blood sugar, blood fats, and real-time food responses.

How Did We Evaluate Zoe?

1. Brand Credibility

   To evaluate ZOE, we considered several key factors, including the brand’s age, background, public reputation, and third-party ratings. Founded in 2017, ZOE is a relatively new fitness tech company focused on personalized nutrition through scientific testing. Its partnerships with research institutions like King’s College London and Harvard add credibility to its science-backed approach, especially in a market where many wellness brands lack rigorous clinical grounding.

   We also looked at customer sentiment through trusted review platforms. On Trustpilot, ZOE has earned a 4.2 out of 5 rating from over 12,000 users. This high volume of mostly positive feedback reflects strong user satisfaction, particularly with the app’s functionality, the depth of nutritional insights, and the personalized nature of its program. That said, there are also some negative experiences reported, often related to customer service or cost.

   We examined ZOE’s Better Business Bureau (BBB) profile, where it holds a C rating. This lower grade indicates a pattern of unresolved complaints or concerns around billing, customer service responsiveness, or order fulfillment. While BBB ratings don’t always reflect the full customer experience, they highlight potential friction points that shouldn’t be ignored.

   Our evaluation suggests that ZOE offers a valuable and well-regarded product, but may fall short in areas like support and subscription management by weighing the brand’s scientific foundation, customer reviews, and service-related ratings.

2. Consumer Responses And Feedback

   We based our assessment of Zoe on a broad sample of Trustpilot reviews, which revealed a mix of positive outcomes and recurring user frustrations. This approach allowed us to get a clearer picture of how the brand delivers on its promises.

   Many users shared that Zoe helped them feel noticeably better, reporting improvements in sleep, digestion, and energy levels. They appreciated the insights from glucose and gut microbiome testing and found the app easy to navigate. Several reviewers also highlighted prompt and helpful customer service that made their experience smoother.

   At the same time, a number of users raised concerns about Zoe’s subscription model. Common complaints included unexpected charges, difficulties cancelling memberships, and being billed for expired or unused kits. Some felt the advice they received was too basic to justify the high cost, and a few early research volunteers claimed the company didn’t honor its original access promises.

   This mix of strong satisfaction with the testing and app experience, paired with consistent frustration over subscription policies and follow-up support, helped shape a realistic view of Zoe’s strengths and limitations.
