- 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 800 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, 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.

Had some problems initially buying from Amazon as there was no way for the company to track it and it disappeared for a while. I sounded like it would be quite complicated if it didn’t show up. Luckily it did and the results arrived very quickly. Literally has changed my life. I had been to allergist who said I was allergic to nothing. I had been to specialist and no explanation for my Gastro intestinal distress. Understanding sensitivies Makes my life make sense. The foods I thought I was allergic to, not anaphylaxis, but definitely distress when eating, while not popping on the allergy test Were definitely confirmed here. I bought this with the hope of the advertising reducing pain and inflammation. I haven’t really seen results in that department but the results I have seen have been amazing. I wasn’t thrilled to getting my results a month before the holidays and finding out I have Hi sensitivities to every Holiday food there is, But I was in such constant pain I was willing to make adjustments and have non-traditional holiday meals. I knew they were foods like potatoes and eggs that would create great distress on my insides. It may be TMI but I know it will be helpful to know, my insides were a mess with gas and bloating on a daily basis. There were times I thought I must have intestinal cancer and was dying the pain was so bad. I was constipated all the time. Again, the knowledge I received from this test, changed everything. I was not thrilled and very very overwhelmed with the amount of foods I had intolerances to. It was right on target with foods I knew I already had problems with. I was super excited that it was egg white causing problems because I don’t like them anyway. I immediately made myself toast with egg yolks and was in heaven and zero pain! Again, the results are super overwhelming and you have to take them in a little bit at a time. Make changes as you adjust. I called the company and spoke to the nutritionist for an hour and a half. He was super awesome! Answered all my questions and explain things patiently to the point I wasn’t freaking out anymore. I did All the tests And while it’s helpful knowing the vitamins and minerals I don’t metabolize correctly and the environmental stuff because that makes a lot of sense with the Health issues I have, it was nice confirmation but beyond that I haven’t done much with the information because I don’t know that I can. The food portion though I referred to again and again. It is too much to process at once so I go back to it frequently and realize I can have food so I didn’t think I could originally from being so overwhelmed. The first week I just ate the foods that I had on hand that I didn’t have any problems with. I eat as much as normal. The only big change I needed to adjust to was not having my half-and-half in my coffee. Or I should say the coffee in my half and half. I use about half a cup for my latte. I could have coconut and almond milk but that is not something that excited me in anyway shape or form. I like my coffee Creamy and they’re just not rich enough. I enjoy one cuppa caffeine a day and I wasn’t willing to give it up so I suffered through. The first week, with just that one change, I lost 4 1/2 pounds. I felt better. My gut started feeling better. It was significant enough that I had the courage to stick to the plan. My diet became very limited in choice, But again the significant improvement and continual weight loss kept me on track. I started feeling better and better inside. I thought there were things I could never give up, like cooking with garlic! There were many items on the list I thought I never had a problem with. But as my insides started feeling better and better, I quickly and painfully realized that I did indeed have a problem with those items! I was just in so much pain all the time I never noticed. When I was sick with Covid I had made myself some soup with garlic to help me breathe. This was only within the first two weeks of cutting the intolerant food out. And let me tell you, the pain I felt after feeling so much better convinced me that I don’t need garlic in my food anymore.In less than three months, 32 pounds melted off. I emphasize I still ate as much as before I just ate foods I wasn’t intolerant to. I did not add exercise yet. While I wasn’t pleased with some of the substitutions I had to make, it honestly was not as difficult as an adjustment as I thought it would be. I have to admit after three months I started cheating because I was feeling deprived by my lack of variety. The weight loss stopped but that’s OK because I’m getting used to my new body and I can’t afford to keep buying new clothes. I plan on recommitting soon as I can tell the difference in my insides. Even though it’s only about 20% of the past discomfort, it really isn’t worth it when I know how good I can feel. When I eat new foods that aren’t on the list, I know immediately if they are not OK. If you were ready to make a significant change in your life, this is well worth the investment. I had like five people who saw the changes in me and got it themselves. Those who abuse the information have seen improvement. Those who were overwhelmed And didn’t bother are still suffering. Again I have to stress it is very overwhelming to get these results. Do not let it discourage you. You just have to be ready to change. If you are just take it bit by bit and you will see results

I decided to try this test after dealing with ongoing stomach discomfort that I couldn't explain. The process was simple, the results came back quickly, and it gave me useful insights that helped me make better food choices.

I stupidly ordered two tests and failed to do my research prior to doing so. The one test that I opened was never used, and the other, thanks to Amazon's great service, was returned. You have to register our kit, but that process was worrisome for me, given the information they were collecting. From their website: "The Company collects only the PII that you voluntarily provide to us, such as when you register to use the Services, set up a profile, create content, sign up for a special offer, enter a sweepstakes or promotion, or complete a survey..... ....The information we collect is statistical data and may include personal information, and we may maintain it, or associate it with personal information we collect in other ways, or receive from third parties... ...We may use the information we have collected from you to enable us to display advertisements to our advertisers’ target audiences... ...We may disclose personal information that we collect or you provide as described in this Privacy Policy to the following: To our subsidiaries and affiliates.

US post office took a good 14+ days to get the item to the testing lab. Once it was at the lab, it was finished within two business days. It is a fairly comprehensive test doing many different categories however, there’s some things that I assumed would be tested that were not. Because I am celiac I really wanted some of the grains like sourgum flour tested . There is a download app that you can use to access easier than your files. However, my app does not pull any of the spices and several other categories so you can’t always trust it and I go to the file to doublecheck. I had a similar test done through my naturopathic physician‘s office several years ago except they use blood rather than hair. As it is sensitivity testing, I know that your gut can heal from various reactions and it seemed like in some cases I had however, eggs did not show up as reactive at all and yet they still are for me so I’m wondering about that one overall I’m glad that I did it But I would be disappointed if I’d spent quite a bit more money. I purchased it on Amazon prime days.

We spent over $6000 last year trying to diagnose the myriad of digestive issues I was having and the only answer we got, which I had known since I was 14, was "you have severe chronic IBS". My life was becoming unmanageable and I was in daily pain and discomfort. I knew I had some food intolerances, but I had no idea how many I truly had and what was causing them. I purchased a different diagnostic product and was able to find a myriad of foods that were bothering me, but the information was still too vague. For example, according to that testing - I couldn't eat apples. I wanted more information so for a very small price point tried the 5 Strands. I got my kit, sent in my hair, and about 6 days later - I had the most comprehensive report that gave me so much more information than I thought possible (via email and via the website). I love that the test breaks foods down, for example, my previous testing indicated I couldn't eat apples. Through 5 Strands, I've learned there are two apple varieties that I can have! The test breaks food into categories like: beverage, dairy, anti-coagulant, food dye, etc. Even better - fruits and vegetables that come in varieties are broken down (like red, yellow, green). With the vegetables, the test even tells you if you can have it in it’s raw form or cooked form! My test indicated I have 393 food intolerances. While that feels overwhelming, now that I'm several weeks into my elimination diet and learning what I can have - I finally feel like I have my life back. Two years ago I considered applying for disability because I couldn't make it more than an hour without pain. Now, I'm about to go back to work full time and I'm in the best physical shape of my life. I rarely have issues, and to be honest, I'm not even convinced I have "IBS". I have A LOT of food intolerances, to many of the common foods and it has been work to figure out how to substitute quinoa and hemp milk for everything ;) BUT - I'm getting healthy and I feel better than I've felt in decades. Without this test - there’s no way I would have known I can tolerate cooked carrots vs raw for example. My only small complaint was that the test results aren't in Excel format. I'm an excel person and I wanted to be able to sort the data in different ways. I put it all into a spreadsheet myself, but it would have been a great option. That's the most minor detail though and it's hardly worth mentioning because this test is so worth it. I've made videos on my Facebook, talk about it to my friends, and am buying them for my children. Everyone should have the opportunity to gain this much insight into their dietary health!

I was so excited to receive these tests especially after reading all the positive reviews. My daughter was recently diagnosed with possible celiac disease and I was hoping this would give us a more clear direction. I was even considering testing my Great Dane puppy but after receiving the results and diving into the website where they answer common questions, I learned more about their testing. The advertisement for these tests were a little misleading since they test the hair samples using Bioresonance technology. Bioresonance works by scanning a hair sample to create a profile of the energies that radiate from a person or pet creating an energetic blueprint or profile. It is then compared to all of the energetic profiles of all of the other items they test for. If these do not harmonize then there is an intolerance or imbalance detected. They come across as doing a full DNA test but that is not what they do. It’s more of a snapshot of what is in your system at that moment. I spent almost $300 on tests for 3 family members and I am questioning whether it was worth it. The test results came back saying we were intolerant to most of the healthy foods we consume on a regular basis which left us puzzled. Their list of tolerable foods specifically for us contained foods we know do not make us feel better i.e they suggested beef instead of chicken/turkey which I have not had beef for 15yrs because of health reasons. We will try eliminating some of the foods to see if it helps but since it’s not purely genetic based, we are reluctant to take it as seriously.

I rarely leave reviews, but this deserves one. 5Strands was one of the most helpful utilities I’ve ever used for understanding my body. The process was straightforward, the results were easy to read, and most importantly it gave me a clear roadmap to identify tolerances around food, nutrition, minerals, and the efficiencies or inefficiencies in my digestive system. What made the biggest difference for me was how actionable it was. Instead of guessing, I was able to make targeted adjustments, follow the elimination guidance, then reintroduce items intentionally. That structure alone removed so much confusion and helped me make better decisions day to day. This truly helped transform my life. If you’re someone who has been trying to figure out what is helping or hurting your body and you want a practical, organized way to approach it, I highly recommend it.

WOW! This product really helped me to hone in to what my gut issues have been. So far, I have been able to cut out 99% of the items that are irritating my gut. Don't mistake this for a food allergy test, but rather what is making your gut churn with unhappiness. I have struggled for years with IBS, food allergies and intolerances. I have tried medication (epic failure), and after this test, my worst IBS issues are under control. I have been rotating items back in and one I tried yesterday gave me a flare up in the worst way. Caffeine was a killer to me and now I am two weeks free of caffeine and feeling so much better; one day I will try it again but for now, why? Honestly, I miss black pepper more than caffeine, but it's worth it.
