Introduction
Feeling bloated after a meal? Struggling with low energy, digestive discomfort, or unexplained skin flare-ups? According to findings from the PAFA project, over 30% of adults in the UK say they've experienced unpleasant symptoms or illness after eating certain foods, suggesting food-related issues are more common than many people realise. And when your body’s trying to tell you something, it makes sense to want answers fast.
Getting help through the healthcare system can take time. One in six patients waits at least two weeks for an initial consultation, and non-urgent specialist treatments can take up to 18 weeks. For many dealing with mild or uncertain symptoms, that’s just too long to wait, especially when private care may not be affordable or necessary.
This is where at-home food intolerance kits come in. They offer a quick, convenient way to spot potential problem foods from the comfort of your own home. Two of the most popular providers in the UK right now are Biosensitive and Supply Life. Both have their strengths, but how do they actually compare when it comes to value, accuracy, speed, and overall experience?
Let’s explore.
Questions to Ask Before Choosing a Food Intolerance Test
Before jumping into a comparison of Biosensitive and Supply Life, it’s worth asking yourself a few key questions. These will help ensure you're selecting a test that genuinely suits your needs, preferences, and lifestyle:
-
What foods are included in the test panel? Make sure the foods tested reflect your actual diet. Some kits are limited, while others are far-reaching.
-
How quickly will I get my results? If time is of the essence, turnaround time could be a dealbreaker.
-
Is the price all-inclusive? Some companies offer add-ons that increase the total cost. Others keep pricing simple and all-in.
-
What support is provided afterwards? Will you be guided through your results, or expected to interpret everything solo?
-
Are the results clear and usable? A test is only helpful if you can actually understand what to do with the results.
With those in mind, let’s explore how each brand performs across these criteria.
Test Methodology: What’s Actually Involved?
If you’ve never done a food intolerance test before, the process might sound intimidating, but it’s actually pretty simple.
Most at-home kits use a method called IgG antibody testing. It’s a well-established approach that looks at how your immune system reacts to different foods. All you need to do is take a quick finger-prick blood sample, pop it in the post, and wait for your results to arrive.
-
Biosensitive: Offers one all-inclusive test covering over 200 foods, including dairy, nuts, grains, fruits, and vegetables. There’s no need to choose between packages or pay extra to get full coverage. The whole process is designed to be as easy and hassle-free as possible.
-
Supply Life: Uses the same IgG testing method but splits its services into three tiers. Coverage ranges from 64 to 200+ foods, depending on the package.
So while the core science is the same, the way each brand presents its testing experience differs slightly.
Biosensitive focuses on keeping things streamlined with one all-in-one test, while Supply Life offers more flexibility through its tiered options, giving users the ability to choose based on the number of foods they want tested.
Both brands provide reliable and similar testing methods, allowing users to comfortably perform the test at home without any fuss.

Laboratory Quality & Accreditation: Trusting Your Results
When it comes to testing your health, lab quality isn’t just a bonus, it’s essential. Knowing your sample is handled with care and precision helps you feel confident in the results and the next steps you’ll take.
-
Biosensitive: Partners with a UK-based laboratory that holds ISO 13485:2016 accreditation, demonstrating compliance with internationally recognised medical testing standards. Each sample is double-tested for accuracy, and its processes are audited annually by SGS, a UK representative for the MHRA, ensuring rigorous oversight of both the blood collection kits and testing procedures.
-
Supply Life: Works with a Cambridge-based lab that also holds ISO 13485 accreditation, plus ISO 9001 certification for quality management. Like Biosensitive, they double-test each sample to ensure reliability.
In short, both providers operate under strict quality standards, giving you peace of mind that your results are both accurate and trustworthy.
Turnaround Time: How Quickly Can You Take Action?
When you're trying to figure out what foods might be causing you discomfort, waiting weeks for answers can feel frustrating. A quicker turnaround can mean faster relief and more confidence when making dietary changes.
-
Biosensitive: Typically delivers results within 3-5 days, and the test kit itself is dispatched within 24 hours of ordering, so you can get started without delay. Many users highlight the speed as one of the biggest benefits, helping them take action and feel better faster.
-
Supply Life: Usually takes around 7 days, which is still fairly quick by industry standards. While they highlight fast delivery, they don't provide a specific dispatch timeframe for test kits.
If speed is high on your priority list, Biosensitive gives you a faster route to useful insights and a potential improvement in how you feel.
Pricing & Value for Money: Which Offers Better Value?
Cost can be a deciding factor when choosing between at-home food intolerance tests. While both brands deliver strong offerings, their pricing models are quite different, and that can make a big difference depending on your budget and goals.
Here's a detailed breakdown:
| Service | Price (£) | Foods Tested | Consultation Included | Explanation |
|---|---|---|---|---|
| Biosensitive Premium Food Intolerance Test | £125 | 200+ | Yes | One test covers everything. Straightforward and affordable |
| Supply Life (Core) | £137 | 64 | Yes | Lower-tier test with a limited food panel |
| Supply Life (Essential) | £207 | 200+ | Yes (7-day support) | Mid-range option with broader coverage and added support |
| Supply Life (Complete) | £239 | 200+ | Yes (30-day support) | Premium package offering full coverage and extended coaching support |
Biosensitive offers extensive food coverage in one straightforward and budget-friendly package, ideal for those who prefer a clear and simple option. That said, not everyone wants a single streamlined solution.
Some users appreciate being able to choose a level of support that matches their specific goals. This is where Supply Life comes in. Their tiered pricing gives users flexibility to tailor their experience, though this variety does come at a higher overall cost.
Post-Test Support & Consultation: Will You Get the Help You Need?
Making dietary changes based on your test results isn’t always easy, especially when you're unsure where to begin. That’s where having access to expert support can make a big difference, helping you understand your results, build confidence in your next steps, and avoid unnecessary food restrictions.
-
Biosensitive: Includes a one-to-one consultation with a Biosensitive coach to explain your results and offer personalised next steps. Users often highlight how helpful it is to ask questions directly. Biosensitive also provides ongoing support and resources to guide your elimination diet and help you put your results into action.
-
Supply Life: All three packages include a follow-up call and guidebooks. For those opting for the Essential (£207) or Complete (£239) packages, you’ll also receive a consultation with a qualified nutritionist, providing tailored guidance based on your results and goals.
Both providers ensure you won’t be left figuring it all out on your own. The level of support may vary depending on which package you choose, but in both cases, you’ll have access to helpful and informed guidance to support your dietary changes.
Credibility & Brand Trust: Who Can You Rely On?
When you're investing in a health-related product, trust matters. You want to feel confident that the brand you're choosing is reputable, transparent, and delivers what it promises.
-
Biosensitive: An exciting brand disrupting the at-home testing market by offering reliable testing at a more accessible price point.

Customer Reviews & Testimonials: Real Experiences
What do actual users think? Both Biosensitive and Supply Life receive consistently positive reviews, but what users appreciate about each one differs.
-
Biosensitive: Customers often mention how quick and simple the experience is. Many highlight the clarity of the report and ease of use at home. Some noted significant improvements in symptoms like eczema after making dietary changes based on the results.
“Ordering was easy, the kit arrived quickly, and the instructions were clear, so taking the test at home was no problem at all. I sent it back the same day and got my results via email pretty quickly. The report was really easy to follow and actually made sense, it flagged a couple of foods that might be behind the bloating I’ve been dealing with for ages. I had a 1 on 1 consultation where I was able to ask specific questions, which was so helpful! I've only just started cutting my problem foods out (dairy and wheat) but I’ve honestly noticed a big difference already. Would definitely recommend!” Sam - Biosensitive customer
-
Supply Life: Reviewers frequently praise the supportive consultations and helpful post-test guidance. The added recipes and food swap advice were especially popular with users looking for structured help to apply the results to everyday eating.
Overall, both brands leave users feeling empowered to make meaningful changes to their diet and health.
