Food Intolerance
Struggling with bloating, fatigue, or brain fog?
A Food Intolerance Blood Test could help uncover the hidden foods behind your symptoms.
Unlike allergies, food intolerances often trigger delayed immune responses — making them difficult to identify without testing.
Bloating, Fatigue, or Brain Fog After Meals?
Food Intolerance Blood Test – Starter, Advanced, or Comprehensive to Uncover Triggers
Tired of unexplained bloating, sluggishness, or flare-ups that ruin your day?
Food intolerances – delayed immune reactions to everyday eats – can mimic IBS, allergies, or “just bad luck,” leaving you foggy, tired, and frustrated without answers. Unlike immediate allergies, symptoms like cramps, low mood, or skin issues hit hours/days later, hard to trace. Our at-home Food Intolerance Blood Tests measure IgG antibodies to common foods, spotting sensitivities so you can eliminate triggers and reclaim energy.
New 3-tier launch:
Starter for basics, Advanced for expanded checks, Comprehensive for full profiling.
All with a professional nurse at home – get personalised insights without guesswork.
The Hidden Culprits in Your Diet – Why Food Intolerances Are Sabotaging Your Health
Your immune system flags certain foods with IgG antibodies – a delayed response causing inflammation over time. Common triggers (dairy, wheat, eggs) build up, leading to bloating, gas, cramps, constipation/diarrhoea, fatigue, brain fog, headaches/migraines, skin issues (acne/eczema/rashes), mood swings/irritability, joint pain, or low energy – often misdiagnosed as stress, IBS, or “ageing.”
The misery? Symptoms linger, disrupting meals, workouts, or focus – years of trial-and-error diets without relief. Risks rise with gut conditions, stress, or poor absorption; untreated, it worsens inflammation or nutrient gaps. If you’re veggie/vegan, on meds, or have family sensitivities, test now – IgG reveals patterns for targeted elimination, not restriction.
Stop the cycle – identify, remove, and thrive.
Food Intolerance Signs Stacking Up? When to Test
These delayed reactions hit anyone – spot if they fit:
- Persistent bloating, gas, cramps, or irregular bowels after eating?
- Fatigue/low energy, brain fog, headaches, or poor concentration?
- Skin flare-ups (acne/rashes/eczema), mood changes, or joint stiffness?
- Unexplained weight issues, low mood/irritability, or slow healing?
- Triggers: Restrictive diets, long-term gut concerns, or desire for personalised guidance?
Common in UK (processed foods/stress), but reversible.

Conquer Food Intolerances – Simple Plan After Results
IgG insights + symptoms guide an elimination diet (remove suspects 2-4 weeks, reintroduce one-by-one):
- Diet Tweaks: Swap triggers (e.g., dairy-free alternatives, gluten-free grains); focus anti-inflammatory foods (fish, berries).
- Support Steps: Hydrate, probiotics for gut health, track symptoms in a journal.
- Professional Help: Nutritionist/GP for plans; retest if symptoms shift (most once is enough).
- Lifestyle: Stress reduction (yoga), balanced meals to avoid new sensitivities.
Tier up for more foods covered – Comprehensive gives broadest clarity for complex cases.
Which Test Matches Your Symptoms?
Starter vs. Advanced vs. Comprehensive Comparison
All nurse venous draws for precise IgG measurement – choose by coverage (same home process, 7-day PDF results with elevated/low/normal flags and food lists).
Food Intolerance Starter Blood Test
Basic IgG panel for 20 common triggers (e.g., almond, apple, celery, cod fish, carrot, casein, egg white/yolk, hazelnut, milk, peanut, peach, potato, rye flour, sesame seed, shrimp, soya bean, tomato, walnut, wheat). Ideal for first-timers or mild symptoms. (IgG to essentials like dairy, eggs, nuts, grains.)
- Best For: Quick scan if bloating/fatigue hints at top culprits; budget entry.
Food Intolerance Advanced Blood Test
Expanded IgG to 34+ foods (builds on Starter with onion, orange, banana, oat, buckwheat, cabbage, rice, cheese (cheddar), salmon, chicken meat, corn (maize), crab, tuna, garlic, white bean, mustard). Deeper for moderate issues. (IgG to broader everyday eats like fruits, grains, fish, meats.)
- Best For: Ongoing digestive/mood/skin problems; when basics don’t explain (e.g., fruit/seafood reactions).
Food Intolerance Comprehensive Blood Test
Full IgG profile for 80+ foods (expands to mango, coconut, brazil nut, whey, beef, lamb, pork, turkey, barley, gluten, pecan nut, sunflower seed, candida albicans, lentil, lima bean, green pea, brewer’s yeast, apricot, avocado, blueberry, cranberry, grapefruit, lemon, papaya, pear, pineapple, plum, raspberry, grape, strawberry, watermelon, asparagus, green olive, broccoli, cauliflower, cucumber, green bean, green pepper, red kidney bean, pumpkin, soya bean, spinach, mackerel, rye flour, chickpea, chocolate, coffee, honey, pistachio). Thorough for chronic/complex. (IgG to complete diet: meats, seafood, nuts/seeds, grains/legumes, veg/fungi, fruits/berries, extras like yeast/candida.)
- Best For: Persistent/long-term concerns (e.g., IBS-like, multiple symptoms); full elimination guidance across all groups.
Unsure? 70% start with Starter – upgrade if results miss triggers or if you want a deeper dive
(e.g., Advanced for fruits/nuts, Comprehensive for everything). All UK-accredited labs, confidential.
Ease Your Worries – Testing Made Simple
- Basic or Full? Starter for suspects; Advanced/Comprehensive for thoroughness (e.g., if gut/mood chronic).
- Reliable? Venous samples + labs give precise IgG; indicator, not diagnosis – pair with symptoms/GP.
- Diet Changes Daunting? Results include guidance; most see relief in weeks with pro help.
- Privacy/Repeat? Confidential; one-time for most, retest if life changes (e.g., new diet).
