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 provides an easy way to test without needing to go to a doctor to have bloodwork done.

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.

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.

Methodology

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.
