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.

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.

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
- Vitamin D: Commonly observed, particularly in regions with limited sunlight exposure or inadequate dietary intake. It plays a crucial role in bone health.
- 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.
- Iron: A prevalent deficiency worldwide, especially among women and individuals with restricted diets. Iron deficiency can cause fatigue, weakness, and impaired cognitive function.
- 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
- Pregnant Women: Increased nutrient demands to support fetal development can lead to deficiencies if dietary intake is insufficient.
- Infants and Young Children: Rapid growth and development increase the risk of deficiencies, especially if their diet lacks variety.
- Older Adults: Reduced nutrient absorption, limited dietary intake, and certain medications can contribute to deficiencies in vitamins such as B12, D, and folate.
- 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.

FAQ
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.
