Main highlights

•IDENTIFY WHICH FOODS MAY BE CAUSING YOUR SYMPTOMS. Food intolerances happen when your gut microbiome and digestive enzymes can’t 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, we’ll 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.

Main highlights

•WHAT IS AN INTOLERANCE / SENSITIVITY? Intolerances and sensitivities are a result of your body not being able to process certain food or environmental items properly, often causing discomfort symptoms, such as acne, digestive issues, joint pain and migraines. It’s important to understand that intolerances differ from allergies, as allergic reactions stem from an immune system response whereas intolerances are developed over time and do not involve the immune system.
•950 ITEMS TESTED. Our comprehensive intolerance test will check for sensitivities across 950 food items including grains, fruits, vegetables, gluten, and preservatives. It also tests for sensitivities across 190+ environmental items including pollen, plants, animal dander, and even cleaning solutions.
•EASY TESTING PROCESS. You can easily carry out the entire testing process from the comfort of your home! (1) Register the kit online (2) Collect hair samples (3) Send back to 5Strands (4) Receive testing results via the customer portal within 5-7 days of your sample's arrival. Be sure to keep your tracking information when sending back hair samples.
•ENSURING YOUR SUCCESS. We highly recommend that you go through this process with an open mind and ask us as many questions as you need to be fully clarified! Most importantly, it’s crucial to be proactive with your results and give the process ample time to take effect as intolerances usually take weeks or months to develop and will not reverse overnight.
•HOW TO USE YOUR RESULTS. Your test results will identify specific food and environmental items that your body may have a mild, moderate, or severe intolerance to. Once you receive your results, it’s important to consistently eliminate these items from your diet or lifestyle over the recommended 6-8 week timeline to allow your body ample time to heal and rebalance itself.

Main highlights

•FIND ANSWERS FOR YOUR UNEXPLAINED SYMPTOMS. Your discomfort symptoms including bloating, gas, eczema flare-ups, constipation, joint pain, or migraines are most likely due to food and environmental intolerances, while symptoms like brittle nails, muscle cramps, inflammation, and dry skin are often signs of nutritional imbalances. Identifying the specific items that trigger these sensitivities and imbalances is a huge first step towards restored comfort and well-being.
•TESTS 998 FOOD & ENVIRONMENTAL ITEMS. Our complete health assessment includes a food & environmental intolerance test kit, vitamin & mineral imbalance test, and heavy metals & minerals imbalance test. Your food intolerances may contribute to your imbalances, making it crucial to understand both at the same time (ex: your intolerances may cause inflammation at the cellular level, inhibiting proper nutrient absorption that leads to an imbalance.)
•GET FAST RESULTS IN 4 EASY STEPS. You can relax at home while completing the entire testing process! Simply (1) Register your food sensitivity test kit online. (2) Collect and bag your hair sample. (3) Send your sample back to 5Strands with the included prepaid shipping materials. (4) Receive your test results via the registered email in 5 days after our lab receives your hair sample.
•USE YOUR RESULTS TO TAKE PROACTIVE ACTION. Utilize your intolerance test kit results to (1) Eliminate trigger food & environmental items from your diet and lifestyle over a 6-8 week period. (2) Identify which vitamins & minerals your body is not absorbing properly, enabling you to prioritize consuming the whole-food option of those nutrients for optimized absorption. (3) Uncover the specific metals & minerals your body has trouble eliminating or processing so you can assess sources of exposure.
•YOU’RE NOT ALONE IN YOUR HEALTH JOURNEY. At 5Strands, we strive to provide you with all the knowledge and resources needed to achieve true comfort and relief from discomfort. We understand how challenging and confusing intolerance testing for adults and kids can be, and encourage you to reach out to our fully-equipped staff to clarify any questions or concerns you may have.
