5 Best At-Home Vitamin D Tests

5 Best At-Home Vitamin D Tests

About 41.6 percent of people have a vitamin D deficiency, with the highest rate seen in Black (82.1 percent) and Hispanic populations (69.2 percent).

Vitamin D helps maintain strong bones and muscles. Still, research shows vitamin D is important for more than just the health of your muscles and bones. A vitamin D deficiency may be associated with an increased risk of heart disease, diabetes, autoimmune disease, and cancer.

Thankfully, testing your vitamin D levels is relatively easy. Keep reading to learn about five of the best at-home vitamin D tests to help you find fast, easy, and accurate answers to whether your vitamin D is in a healthy range.

A vitamin D test tells you how much vitamin D is in your bloodstream. Both the vitamin D you eat and naturally produce from sun exposure start as the inactive form. Later, the liver and kidneys convert 25-hydroxyvitamin D (25-OH D) into the biologically active form, 1,25-dihydroxyvitamin D.

Most vitamin D tests measure the total amount of 25-OH D in your blood because it has a longer half-life than 1,25-dihydroxyvitamin D. These tests can tell you if there’s too much or too little vitamin D in your body.

A vitamin D test can determine whether you have a vitamin D deficiency or excess levels in your body.

You may have excess vitamin D levels if you’re taking large doses of vitamin D supplements. Vitamin D deficiency is more common. People who are at a higher risk of developing a vitamin D deficiency include:

  • people with limited sun exposure
  • older adults
  • people with chronic kidney disease or liver disease
  • people with a history of bariatric surgery
  • people with conditions affecting the intestines, such as Crohn’s disease or gastric cancer

Many people with a vitamin D deficiency don’t experience any symptoms. However, a healthcare professional can identify the following signs of a vitamin D deficiency:

  • low calcium levels
  • overactive parathyroid
  • fragile bones
  • muscle twitching and weakness
  • fatigue
  • rickets, which may develop in children

If you’ve had a vitamin D deficiency in the past, talk with your healthcare professional about whether at-home tests can help with monitoring your vitamin D levels, or if monitoring is needed at all. Your healthcare professional can also help determine what frequency of testing may be needed.

There’s a lot to consider when it comes to choosing an at-home vitamin D test. To select the best, we reviewed available research, customer experiences, price, and each company’s process.

Are at-home vitamin D tests accurate?

User error is always a possibility with at-home tests, so it’s important to follow the instructions provided carefully. Overall, at-home vitamin D tests are as accurate as traditional lab tests.

How often should I test my vitamin D levels?

If you have a vitamin D deficiency, testing your levels 3 months after beginning treatment may help you and your healthcare professional determine if the plan is working or if it should be adjusted.

Otherwise, if your vitamin D levels typically fall within the recommended range, testing them twice a year — in the spring and again in the fall — can alert you to any changes and help ensure they continue to stay within a healthy range.

There isn’t much research available on the benefits of screening for vitamin D deficiency, so it’s best to speak with your healthcare professional first before trying an at-home test.

What are appropriate vitamin D levels?

Most vitamin D tests measure the total amount of 25-OH D in your blood.

According to the Office of Dietary Supplements, normal 25-OH D levels range from 20 nanograms per milliliter (ng/mL) to 50 ng/mL. Levels below 12 ng/mL are typically associated with vitamin D deficiency.

How can I increase my vitamin D level?

You can increase your vitamin D levels by spending time in the sun, eating foods with vitamin D, or taking supplements containing vitamin D.

Foods high in vitamin D include:

Vitamin D is an important micronutrient for your health, as it plays a role in bone and immune health. Many people with vitamin D deficiency don’t experience any symptoms. So, testing your vitamin D levels may help maintain your health.

An at-home test is a convenient way to monitor your vitamin D levels. Note that there isn’t much research available on the benefits of screening for vitamin D deficiency.

Before ordering a test, it’s important to speak with your healthcare professional to determine if testing is needed and, if so, how often. Your healthcare professional can also recommend any at-home testing options and advise you on your results and how to best treat a vitamin D deficiency.
