The 5 Best At-Home Vitamin Deficiency Tests Of 2024, From An RN

If you're on the hunt for a detailed evaluation of your vitamin D, B12, and B9 levels, then this vitamin deficiency test by Labcorp is the best pick for you. Through a simple blood test, you can get insights into your nutritional status, meaning it'll let you know of any possible gaps in your nutrition and recommend foods to help you bridge that gap. One downside, however, is that you will have to go in person to a Labcorp location to drop off your sample and recieve your results.

The testing is done in a CLIA-certified clinical laboratory that performs regular quality assurance testing to ensure the results your receive are accurate.

Labcorp also has a variety of other tests including a men's and women's health tests, hCG pregnancy test, testosterone test, iron deficiency test, and more.

LetsGetChecked has a range of at-home tests available, with vitamin deficiencies included in three of its kits. You can choose between a vitamin-D-specific test, an essential vitamin test (vitamin D, B12, and E), or a comprehensive test that includes all vitamins in the essential test, plus copper, selenium, zinc, and magnesium.

The brand is transparent in its guidelines; if you're under 22 years old, you'll not receive results for vitamin B12. It also limits blood sample collection days to Monday through Thursday, which you'll need to be mindful of when planning your test. The secure online portal will present your results within two to five days of sending in your sample, and you can expect a nurse to call and discuss any abnormal levels.

We tried it: mbg's own Andreas tried the LetsGetChecked Vitamin D test for himself. You can watch the full video review here.

Everlywell's vitamin deficiency test evaluates either your vitamin D or B levels (although the vitamin B test is currently out of stock). The tests are relatively inexpensive, although they have a slightly longer wait time for results. The brand's user-friendly packaging and directions make the whole testing experience fairly simple: You simply prick your finger with a lancet and send back your sample in a pre-labeled envelope. Your results will be delivered in a secure portal on the Everlywell app. A pre-recorded information video will help run through your results; however, it won't be personalized to your specific reading. Taking the results to your primary care physician is a great way to ensure you're actually understanding the next steps.

If you want a complete picture of your vitamin and mineral deficiencies, 5Strands is a great option. For only $66, your sample is tested against 80+ vitamins and minerals. The results will reveal only the nutrients you are deficient in, so you won't see any levels listed for those that are within "normal" range.

This brand is unique in that it requires just a few strands of your hair from your head rather than blood. The high-level technology uses bioresonance, which compares the light frequency of the hair sample to the electromagnetic frequencies of organic and inorganic matter.

Customer reviews are mixed on 5Strands, with the biggest complaint being that the report is very technical and hard to understand. The results give no context as to what an abnormal result means, so you will need to take your results to a health care specialist to translate (which we recommend in any case).

As a brand, Rootine prides itself on being a community of health enthusiasts. The company was founded by a working mom who wanted to dive deeper into the reasoning for her chronic fatigue.

This finger prick test includes vitamin B9, B12, D, hsCRP, and homocysteine (inflammation markers), providing solid insight into potential vitamin deficiencies. Rootine is the first brand to use a genetic assessment in its algorithm to better understand each individual's unique nutrient needs—and there's also professional coaching offered.
