Confirmed deficiencies doctors ignored
Going to the doctors for lightheadedness, everything kept coming back fine other than my low red blood count. I had all of the symptoms of b12 deficiency, including the grey hair. Having gut issues my body wasn’t absorbing the nutrients I needed. This test confirmed my vitamin deficiencies I knew I had. I don’t trust bloodwork’s especially since my local hospital changed what is now normal for results, and other hospitals each have their own differences in analyzing blood. Nothing is full proof but this test definitely helped me and feel better.

Fixing my energy
Quick, painless sample, and the final report showed me exactly where my body was struggling to absorb nutrients. It made it incredibly simple to tweak what I pack in my cooler for long trips.

Not Very Accurate..
I was so excited about this test. I was feeling not the best and am currently going through menopause. I got the results after taking this test and loved the app etc. it seems very informative. I also happened to get bloodwork done at my Dr’s request. My results showed a severe vit d deficiency. But the 5Strands test showed no issues at all with this vit. Very disappointed and feel like it was a waste of money. I will go to the dr from now on for health information moving forward. I would like to say though that this brand has an amazing dog allergy test that changed my dogs life! It indicated all of his allergies and we changed his food and all his issues cleared up.

Reasonably accurate, fair price, includes complete list of items tested
Having never had a vitamin deficiency test done in a doctor's office to compare the results to, I can't really comment on the accuracy of the results. All I can say is that the deficiencies listed in my report made sense to me based on what I know about my health and diet. The directions for collecting the required hair sample were very easy to follow. It took about 2 weeks between submitting my sample and recieving my results. My questions for customer service regarding my results were answered within 14 hours of asking. This test is a reasonably priced option for those of us whose health insurance won't cover the lab test. The following is a complete list of what they test for: 5 Strands Nutrition Test- Nutritional Items Tested Histidine Isoleucine Leucine Lysine Methionine Phenylalanine Threonine Tryptophan Valine Alanine Arginine Asparagine Aspartic Acid Cysteine Cystine Glutamine Glycine Ornithischians Proline Serine Taurine Tyrosine Hydrogen Lithium Nitrogen Oxygen Calcium Magnesium Phosphorus Potassium Silica Zinc Orotate Alpha-linolenic Acid Lecithin Linoleic Acid Omega 3 Omega 6 Omega 9 Nickel Strontium Vanadium Bioflavonoids (anthoxanthins) Fluoride Gamma Aminobutyric Acid (GABA) Glutathione Melatonin S-Adenosyl-L-Methionine (SAMe) Boron Chloride Chromium Cobalt Copper Germanium Iodine (aqueous) Iron Manganese Molybdenum Selenium Silicon Sulfur Vitamin A (retinyl palmitrate) Vitamin B1 (thiamine) Vitamin B10 (PABA) Vitamin B11 (salicylic acid) Vitamin B12 (cobalamin) Vitamin B13 (orotic acid) Vitamin B2 (riboflavin) Vitamin B3 (niacin) Vitamin B4 (adenine) Vitamin B5 (pantothenic acid) Vitamin B6 (pyridoxine) Vitamin B7 (biotin) Vitamin B8 (myo-inositol) Vitamin B9 (folic acid) Vitamin C (ascorbic acid) Vitamin Choline Vitamin D2 (ergocalciferol) Vitamin D3 (cholecalciferol) Vitamin E (alpha-tocopherol) Vitamin K1 (phylloquinone) Vitamin K2 (menaquinone)

Not as informative as expected
Test is easy enough but limited information is provided, which was disappointing. You provide strands of hair and results arrive within a couple weeks. I expected to at least understand if levels were elevated or deficient, not necessarily even a reference range, but it doesn't provide this information. It only lets you know if you have an issue and if it's low, moderate or severe. So you're not going to understand if it's an elevated result or deficient in the specific mineral/vitamin or amino acid but only if you have an issue with it. It's minorly helpful but then i still have to have those retested by my doctor IF i can get them to not dismiss this result, like so many physicians do. It's helpful in the sense that i know i have an issue, but that's it..and i already knew that. If it at least provided whether you are deficient or elevated it would be a phenomenal test because it tests things i never even heard of. So i gave a 3 start for that reason. I'd give a 5 if it provided more information about deficiency or elevation rather than just severity of the issue.

Why I purchased this test
I take supplements regularly and have never known how my body responds. With this test I learned which ones my body can handle as well as which one I should be trying to get through whole foods rather than supplements. I recommend this for anyone who is equally curious. Plus the customer support is wonderful if you have any follow-up questions about your results.

Better planning
Removes the guesswork from my diet. You simply collect a small hair sample and mail it back to get a detailed breakdown of any absorption issues. The data sheet gives a clear blueprint to change up meal prep for better stomach comfort.

Highly recommend
I ordered the 5Strand hair analysis to help address some concerns I have. I got the results back in a timely manner and today did a consultation with Stacey. She went over my test and suggestions on what do do moving forward. She was so easy to talk to and very helpful! I am going to do a food sensitivity test as she recommended and will go from there. I would highly recommend this test and the consultation and I believe it would very beneficial. Stacy went out of her way to call me since I was not sure on how to do a Zoom meeting.

Very informative
The process to collect and submit a sample could not have been much easier. I downloaded the app and results updated on there automatically once they were available. It took about a week from the time I mailed it. The results indicated a lot of items that I needed to address which could be causing symptoms and I have currently restricted my diet and waiting to try adding them back. The whole experience has been easy and straight forward and provided a lot of insight into potentially problematic things I was not considering in my diet/environment. Highly recommend as a starting point if your overhauling your diet to eat healthy to make sure the foods/supplements you choose are a good fit for you individually.

Pas concluant pour moi
En ce qui me concerne décue, je savais déja que plusieurs produits je réagissais et il n'ont pas ressortis dans les intolérances en rouge ni en jaune. Pour moi, en tout cas, pas concluant. Ca c'est seulement mon opinion personnel. Pour cette raison je donne 3 étoiles, parce que je croyais que mes intolérances connues allait ressortir dans le test.
