Our Best Vitamin Deficiency Tests Kits Reviewed

1. LetsGetChecked – Our #1 Pick for Vitamin Test

  • Monitor levels of key vitamins
  • Free shipping both ways
  • Free nurse consultation
  • Results in 2-5 days

LetsGetChecked is our #1 pick for at-home vitamin testing thank to fast results, excellent support, and a variety of tests, which includes individual and panel tests.

Screen your levels for vitamins D and B12, which are essential in maintaining a healthy immune system, skeletal and nervous systems, and generating red blood cells.

The test kit contained everything our researcher needed to collect his blood sample quickly and easily at home. Don’t worry if you’re a little squeamish, all you need is a finger prick sample and our test taker reported that it was totally painless.

You should be done in just a few minutes and no special shipping is required. Simply pop your samples in the discreet prepaid packaging provided and pop them in a post box near you.

We were expecting our results within 2-5 days and were pleasantly surprised that they were delivered in just 3 days after sending our samples to the lab. We found the report to be very straightforward. It lists the biomarker i.e. vitamins, along with your current levels, and whether they fit in the normal range.

If your levels are shown to be deficient you can make the necessary lifestyle changes and monitor your levels to check for improvements with LetsGetChecked’s subscription option, which can save you up to 30%.

If you’re not too clear on your results, it’s easy to schedule a consultation with an experienced nurse through your secure online dashboard. Our researcher found the consultation very helpful, particularly the tips he could implement to improve his vitamin D levels.

The only slight issue with LetsGetChecked is that the Vitamin B Test is only suitable for those over the age of 22. Those under 22 will not receive a test result, so be sure to check any conditions of your test before ordering.

Fasting may also be required before collecting your sample, but as you collect it in the morning, this was no major issue for our test taker.

2. Everlywell – Great for Testing Levels of B Vitamins

  • Several vitamin test options
  • Actionable insights included in the results report
  • Free webinar
  • Results in 2-5 days

If you’re looking to test your levels of B vitamins, Everlywell is a great option with an individual Folic Acid (vitamin B9) test and a panel that measures the three essential B vitamins: B6, B9, and B12.

While Everlywell is a great choice for testing B vitamins, we also love that they have a Vitamin D and Inflammation Test. This test measures both vitamin D and hs-CRP, a protein linked to inflammation, which can indicate if your fatigue, aches, and pains are a result of excessive inflammation.

All you need is a simple fingerprick blood sample, which, like our researcher, you should have no issue collecting, thanks to easy-to-understand instructions. Prepaid packaging is provided to ship your samples back to the lab.

The website states you can expect your results in 2-5 days after the lab receives your sample. Our report was delivered in just 3 days and we were very happy with how detailed it was. It included the current levels of each B vitamin and if they were in the normal range. Plus, you’ll also get guidance on how to improve and maintain healthy vitamin levels to boost your overall wellness.

It’s disappointing that Everlywell only offers one-on-one consultations for positive STI results. However, you can access a group webinar with a healthcare professional that can answer any questions you have about your results report.

  • Comprehensive health and ancestry tests that include vitamin insights

  • User-friendly reports
  • Results within 8 weeks (though it may take longer)

Nebula Genomics provides a comprehensive 30x whole-genome sequencing service that deciphers your entire DNA to uncover all your genetic markers. However, this advanced offering does come with a price tag. The individual kits are rather costly, and on top of that, a regular subscription fee is required.

Despite the expenses, the subscription fee does provide valuable benefits. It includes thorough health testing with added ancestry information. The health analysis covers 27 traits related to various aspects of well-being, such as earwax type, freckling, snacking behavior, nicotine response, and muscle strength. This includes vitamins, though there are no individual or specific vitamin tests and panels. 

It is worth noting that receiving the reports takes some time, as we had to wait for approximately 13 weeks. Nevertheless, the organization of the health traits into four distinct categories—appearance and hormones, behavior and perception, body and athleticism, and nutrition and diet—facilitates easy navigation through the report.

How Accurate Are At-home Vitamin Tests?

It’s crucial to keep in mind that no test can guarantee 100% accuracy. However, at-home vitamin tests are generally highly accurate when it comes to measuring your current vitamin levels. All the companies listed here use accredited labs, ensuring that your samples are processed correctly.

If you carefully follow the test instructions, such as fasting before collecting your sample if needed, you can have confidence in the reliability of your results.

At-Home Vitamin Deficiency Tests: Important Things to Note

It’s important to be aware that there could potentially be hidden fees or unforeseen details that might escape your notice when ordering a vitamin test. However, our thorough research into each provider has revealed that our top choices among at-home vitamin test companies offer complimentary shipping both ways. This means you won’t encounter any extra charges for receiving your kit or sending back your samples.

What’s even better is that these companies also provide consultations free of charge. Keep in mind that several vitamin tests require specific preparations before you take them. For instance, many tests may require you to fast for a certain period before collecting your samples. This step ensures that your current levels are accurately measured.

Certain tests that measure hormone levels might entail additional preparation. For instance, if you’re taking a vitamin C test, you’ll need to abstain from consuming fruits and alcohol for 24 hours before the test to ensure accurate results.

What Will the Results From an At-home Vitamin Test Tell Me?

The results of your vitamin test will tell you your current levels of the biomarkers tested and how they compare to the normal range.

You may also get some information on what your results mean for you, along with insights on how you can improve your levels through diet and other lifestyle factors.

While you learn your vitamin levels, these tests can’t tell you why your levels are out of the normal range. An abnormal vitamin level is not always an indicator of an underlying health condition.

Therefore, it’s recommended that you take your results to your personal healthcare provider, which can advise on additional testing and treatment if needed.

Reading Your Results: What Different Vitamins Mean

Vitamins are essential organic compounds that the body needs in small amounts to maintain optimal health and functioning. They play crucial roles in various physiological processes and affect different aspects of the body. Here’s an overview of vitamins and what they influence:

Vitamin A:

  • Supports vision, especially in low light conditions
  • Promotes healthy skin and mucous membranes
  • Contributes to immune function and cell growth

Vitamin B complex:

  • B1 (Thiamine): Converts food into energy, supports nerve function
  • B2 (Riboflavin): Helps with energy production, supports growth and development
  • B3 (Niacin): Important for energy metabolism and DNA repair
  • B6 (Pyridoxine): Involved in brain development, red blood cell production, and hormone regulation
  • B12 (Cobalamin): Essential for red blood cell formation, nerve function, and DNA synthesis

Vitamin C:

  • Acts as an antioxidant, protecting cells from damage
  • Supports immune function and collagen production for healthy skin, bones, and blood vessels
  • Enhances iron absorption

Vitamin D:

  • Aids in the absorption of calcium and phosphorus for strong bones and teeth
  • Regulates immune function and cell growth
  • Plays a role in mood regulation

Vitamin E:

  • An antioxidant that protects cells from damage
  • Supports immune function and helps with blood clotting
  • Promotes healthy skin and eyes

Vitamin K:

  • Essential for blood clotting and bone health
  • Supports proper calcium metabolism

These vitamins are primarily obtained through a balanced diet, with some being produced by the body through exposure to sunlight (vitamin D). In cases where dietary intake is insufficient, supplements may be recommended to meet the body’s needs. However, it’s important to note that excessive vitamin intake can have adverse effects, and it’s best to consult with a healthcare professional to determine the appropriate dosage and source of vitamins based on individual needs and health status.

When to Test for Vitamin Deficiency?

Vitamin deficiencies can arise when the body lacks sufficient amounts of specific vitamins. Here’s a brief overview of the most common deficiencies, high-risk groups, and associated symptoms:

Most Frequent Vitamin Deficiencies

  1. Vitamin D: Commonly observed, particularly in regions with limited sunlight exposure or inadequate dietary intake. It plays a crucial role in bone health.
  2. Vitamin B12: Frequently seen in individuals following a vegan or vegetarian diet, as it is mainly found in animal-based foods. Vitamin B12 deficiency can lead to anemia and neurological issues.
  3. Iron: A prevalent deficiency worldwide, especially among women and individuals with restricted diets. Iron deficiency can cause fatigue, weakness, and impaired cognitive function.
  4. Vitamin C: Often seen in individuals with limited fruit and vegetable consumption. A lack of vitamin C can lead to scurvy, characterized by fatigue, bleeding gums, and weakened immune function.

Risk Groups for Vitamin Deficiencies

  1. Pregnant Women: Increased nutrient demands to support fetal development can lead to deficiencies if dietary intake is insufficient.
  2. Infants and Young Children: Rapid growth and development increase the risk of deficiencies, especially if their diet lacks variety.
  3. Older Adults: Reduced nutrient absorption, limited dietary intake, and certain medications can contribute to deficiencies in vitamins such as B12, D, and folate.
  4. Vegetarians and Vegans: Eliminating animal-based foods can result in deficiencies in vitamin B12, iron, zinc, and omega-3 fatty acids.

You should also test for vitamin deficiency if you notice the following symptoms:

  • Fatigue and weakness
  • Poor immune function and increased susceptibility to infections
  • Cognitive difficulties and impaired memory
  • Skin problems, such as dryness or rashes
  • Anemia or other blood-related disorders
  • Bone and joint pain
  • Muscle weakness and cramps
  • Changes in mood and mental well-being

It’s essential to maintain a balanced diet, rich in a variety of foods, to ensure adequate vitamin intake. In cases where deficiencies are suspected, consulting with a healthcare professional or registered dietitian can help diagnose and address any underlying deficiencies through dietary adjustments or supplementation, if necessary.

What are the symptoms of abnormal vitamin D levels?

Vitamin D is an essential micronutrient, which helps to keep your bones strong and healthy. Abnormal levels of vitamin D – either too much or too little – can lead to the following symptoms:

  • Muscle pain and/or weakness
  • Joint pain
  • Fatigue, lethargy, or feeling tired
  • Thinning hair
  • Mood changes

Can an at-home vitamin test diagnose a medical condition?

No, an at-home vitamin test cannot diagnose you with any medical condition. They can give you an idea if you have a deficiency in certain vitamins, but they can’t tell you why or the underlying cause.

In your results report, you may also get some actionable insights into diet and lifestyle changes you can make, to improve and maintain your levels. However, if you’re worried about the cause of a deficiency, you should share your results with your healthcare provider who can organize further testing and treatment if necessary.

Will insurance cover the cost of my at-home hormone test?

At-home hormone tests are not usually covered by your insurance, but it is still worth checking with your provider before ordering. However, a number of providers on this list, including Everlywell, accept FSA/HSA cards as a form of payment.

How long does it take to get your vitamin test results?

That depends on the provider. With lab-testing companies, you can expect your test results in just a couple of days. Results from at-home vitamin test providers take a little longer, but usually, you’ll receive them in 2 to 5 days.
