Vitamin deficiencies are startlingly common worldwide. As many as 69% of women of reproductive age globally are deficient in at least one micronutrient, including one in three American women, according to research published last year (the study did not have enough data on men to include these rates).

You can improve your nutrient levels by eating balanced, nutrient-rich meals and taking research-backed, doctor-approved vitamin supplements. But how do you know if you are hitting your vitamin benchmarks, and where there are still gaps in your diet? That’s where at-home vitamin deficiency tests can help. 

These tests use a hair or blood sample you collect and send to their labs to determine whether you are getting enough of one, some or all of the 13 essential vitamins that you can only get through your diet.

We’ve rounded up the best vitamin deficiency tests on the market today.  We made sure that every kit we have listed below is sold by a company with a lab certified to be safe and under government standards like the Clinical Laboratory Improvement Amendments (CLIA). Our list also takes into account how easy the tests are to use, how accurate the results are, how quickly you can expect to get them back, and how easy to understand these results will be.

Guide for Choosing the Best At-Home Vitamin Deficiency Tests

Are At-Home Vitamin Deficiency Tests Worth It?

You may be interested in taking a vitamin or mineral deficiency test if you suspect you might not be getting enough nutrients from your diet.

Some signs of vitamin and mineral deficiencies include:

  • Fatigue: B vitamins, iron, magnesium, and zinc may play a role in energy levels.
  • Skin problems: Skin problems may suggest a deficiency in zinc or B vitamins.
  • Brittle nails: Brittle or soft nails may be due to a biotin or iron deficiency, while white nail beds may be a sign of selenium deficiency.
  • Getting sick often: If you are ill often, you may be curious if a vitamin D deficiency is affecting your immune health.
  • Hair loss: Unexplained hair loss may point to biotin, zinc, or essential fatty acid deficiency.

If you’re experiencing any of these problems, a home vitamin test offers one easy indicator without needing to go to a doctor to have bloodwork done. However, with most tests costing $100 or more, they can quickly become prohibitively expensive. And many doctors don't consider home tests as accurate as blood tests they order based on a patient's symptoms and medical history. Plus, home vitamin tests are not covered by insurance, which most tests ordered by your health care provider would be.

Comparing At-Home Vitamin Deficiency Tests

When choosing a home nutrient test, consider the following factors to find the right one:

  • Cost: Most vitamin deficiency tests range in price from about $50 to $200. The more comprehensive tests will command a higher price.
  • Time for results: Although some can return results in as little as two days, some may take two weeks or more. If you’re anxious to get your results, go with a service with a quick turnaround time, like LetsGetChecked.
  • Availability: Not all tests are available in all states. For example, in New York, you may need to have your healthcare provider order a nutrient test because most of these tests aren’t able to be shipped there.
  • Vitamins tested: You can choose to have one or multiple nutrients tested, depending on your needs or what you suspect. The Comprehensive Micronutrient Test from LetsGetChecked and the Baze Vitamin Test Kit offer the largest number of vitamins and minerals in their tests.
  • Follow up: Both Baze and Rootine offer customized supplements based on your test results, so if you’re looking for a targeted solution that’s paired with your results, one of these tests may be a good fit for you.

Ordering Your Vitamin Deficiency Test Kit

If you’re ready to get started with your vitamin deficiency test, here are the steps you’ll follow for most—regardless of the brand or test you purchase:

  1. Buy the test online (preferably directly from the company’s website).
  2. Register or activate the kit after you receive it, either on the company’s website or the app.
  3. Collect and return your sample using the instructions and materials provided in your kit.
  4. Await your results, which may be delivered via email, the company website, or the app.

These directions may differ slightly between brands, so thoroughly read the instructions and supporting materials that come in your kit. 

Frequently Asked Questions

Are At-Home Vitamin Deficiency Tests Accurate?

These tests are as accurate as tests ordered by your healthcare provider because they utilize labs of the same quality that are CAP-, COLA-, or CLIA-certified, or that have comparable certifications.

However, they only give a glimpse into your overall nutritional profile. It is always best to confirm at-home results with a healthcare provider who can provide a big-picture assessment of whether you are vitamin-deficient, and whether adjusting your diet, adding supplements or other adjustments is the best way to address the issue. 

Who Should Use an At-Home Vitamin Deficiency Test?

Anyone who’s curious about their nutrient levels can use one, but it may be best to use if you’re experiencing symptoms that may be related to nutrient deficiency or if you already suspect that you’re not getting enough of some key vitamins and minerals.

For example, people who follow particular diets, such as vegetarians or vegans may benefit from nutrient deficiency testing to be sure they are getting all the vitamins they need after cutting out certain foods. If you are over 50, it’s especially important to be sure you are getting all the vitamins and minerals you need to keep your immune system and bones strong.

However, some vitamin deficiencies are caused by underlying conditions that may disrupt your ability to absorb micronutrients, such as irritable bowel diseases (IBDs) or Crohn's. Simply eating more of or taking supplementary vitamins after taking an at-home test may not improve your micronutrient levels if you have one of these conditions, so be sure to consult your health care provider.

How Much Do Home Vitamin Tests Cost?

Most at-home tests cost between $50 and $115. The prices depend, in part, upon how many different vitamin and mineral deficiencies the test is assessing. The tests listed here may be slightly more expensive compared to others you may see online, because their labs are high-quality and certified to run complex tests. 

Will My Insurance Cover At-Home Vitamin-Deficiency Tests?

No, none of these at-home tests accept insurance. However, some will accept payments from your pre-tax HSA or FSA accounts. 


We looked at a total of 10 nutrient testing services, but excluded four because their services were not exclusively at-home tests, or because the tests were not CLIA- or CAP-certified. We aimed to include tests that offered a range of nutrient tests as well. We have listed some that allow testing for individual vitamins you may be concerned about, and others that allow you to get a broader picture of your overall vitamin and mineral intake.
