What is Supply Life?
Supply Life is a UK-based company that offers a simple, at-home blood test for food intolerance. Everything is done through the post, which means you don’t have to wait for GP referrals or book into a clinic.
The test itself measures levels of IgG antibodies in your blood across four different subclasses (IgG1, IgG2, IgG3 and IgG4). These antibodies are produced when your body reacts to certain foods, and high levels could suggest a possible intolerance.
What makes Supply Life stand out is that they only use blood, not hair or saliva, and all testing is carried out in an ISO-accredited UK lab using microarray technology.
So let’s take a look at how the whole process works:
Step 1: Choose Your Test Package
There are a few different options when it comes to Supply Life’s food intolerance kits. Prices start at £137 for the Core Test, which looks at 64 common foods.
The more comprehensive packages include testing for 205 or 209 foods and range from £207 to £239. The tests also come with extra support like meal plans, nutritionist consultations, and follow-up guidance.
All kits include free UK delivery and come with everything you need to complete the test from home.
Step 2: Take Your Sample at Home
Once your kit arrives, it’s time to take your sample. The process is straightforward. You use the included lancet to prick your finger, then collect around 4 to 5 large drops of blood into the microvette tube provided.
It takes just a couple of minutes, and there are clear step-by-step instructions included in the pack.
This kind of blood test for food intolerance is so much less hassle than clinic-based tests and it puts you in full control of the process.
Step 3: Send Your Sample Back
When you’ve collected your blood sample, you post it back to Supply Life’s lab using the prepaid packaging included in the kit. The lab is based in the UK and uses advanced immunoassay microarray technology to analyse your results.
Each slide in the lab is printed with food protein extracts from hundreds of different ingredients, including dairy, wheat, seeds, seafood and fruit. When your blood is applied, the lab checks for IgG antibody responses. The stronger the antibody reaction to a specific food, the higher your result will be for that item.
Step 4: Wait for Results
Once your sample reaches the lab, results are typically available within 7 working days. That’s a pretty quick turnaround compared to the wait you might face going through your GP. The report is delivered digitally and includes a breakdown of how your body has reacted to each food.
It’s worth remembering that a blood test for food intolerance doesn’t diagnose allergies, but it can show you which foods might be causing chronic low-level symptoms that build up over time.
Step 5: Understand Your Report
The report you receive will list every food tested, along with your antibody level for each one. These are usually colour-coded or grouped into low, moderate or high reactivity. It’s a really clear way to identify which foods might be contributing to bloating, sluggishness, skin issues or other digestive symptoms.
This can be a game changer if you’ve spent months guessing and trying to work it out yourself.
Step 6: Use the Insights to Make Changes
This is where the test starts to become really useful. You’ll be offered a one-to-one call with a qualified nutritionist who’ll help you interpret your results and put together a realistic plan.
You also get a personalised meal plan to help guide you through the first few weeks of cutting out reactive foods.
Supply Life generally recommends eliminating problem foods for a period of time, then gradually reintroducing them one by one. That way you can track any improvements and figure out what’s really affecting you.
Why Choose a Blood Test for Food Intolerance?
A blood test for food intolerance is one of the quickest and most convenient ways to get insight into your body’s reactions. Unlike hair strand tests or self-diagnosed food diaries, this gives you actual useful data.
Supply Life uses medical-grade technology, and all their tests are analysed in the UK under accredited lab conditions. Everything is designed to be easy to follow, from the sample instructions to the final report.
