IDENTIFY WHICH FOODS MAY BE CAUSING YOUR SYMPTOMS. Food intolerances happen when your gut microbiome and digestive enzymes cant break down a food ingredient. Although gluten and lactose are the most common issues, intolerances can happen with any food item. When these intolerances go unchecked, symptoms like headaches, gas, diarrhea, acne, and bloating may develop.
TESTS 658 COMMON FOOD ITEMS. Our food intolerance test for adults and children covers 14 major food categories: dairy, vegetables, fruits, grains, meats, seafood, nuts, sweeteners, spices, fats, oils, mushrooms, superfoods, beverages, and preservatives.
HOW IT WORKS. (1) Register your test kit on the 5Strands website or mobile app (2) Collect 10-15 strands of hair. (3) Send your sample to our certified lab using the included prepaid shipping materials. (4) Once your sample is received, well email you the results within 4 days. After 60 days, your hair sample will be permanently disposed of.
EASY TO READ RESULTS. Each food item is labeled as Insignificant, Mild, Moderate, or Severe to help guide your elimination plan. This gives you clear directions to begin removing severe intolerance foods, moderate your intake of mid-level triggers, and keep safe foods in rotation to support gut health, digestion, and symptom relief.
3RD PARTY STUDIED & DOCTOR RECOMMENDED. 5Strands is the only intolerance and sensitivity test independently validated through third-party research. Every sample is processed in our certified U.S. lab using a double-pass method for accurate results, and our testing has helped over 345,000 people and pets uncover their food intolerances and environmental sensitivities.

It also screens for common additives such as preservatives, emulsifiers, stabilizers, thickeners, food dyes, sweeteners, probiotics, and prebiotics, giving you a detailed look at potential triggers from both whole foods and processed ingredients.
NON-INVASIVE COLLECTION PROCESS. A small hair sample is all that is required, collected in the comfort of your own home. This method avoids the hassle of needles while giving you reliable data about your bodys interaction with a wide variety of foods.
