Vitamin D Monitoring Test

Easy at-home screening for Vitamin D deficiency

Vitamin D plays a crucial role in your physical well being — yet 40%¹ of Americans don’t get enough. This test allows you to monitor levels and detect deficiencies, which is especially important for older patients or people with gastrointestinal issues² such as celiac disease³.

This test accurately measures your Vitamin D levels

Vitamin D is an important vitamin that plays a role in bone density, insulin production and immune function. The 25-hydroxyvitamin D biomarker is the best way to screen for, and monitor vitamin D levels. We screen for vitamin D using an advanced dry-blood spot card that provides results that are as accurate as labs ordered by a doctor.

Common symptoms related to vitamin D deficiency

Many of the symptoms associated with Vitamin D deficiency are subtle in nature, making it difficult to detect without proper testing. The following indicators are signs you should get screened⁶,⁷,⁸:

Muscle pain

Hair loss

Impaired hearing


*If you are experiencing heart attack symptoms, please see a doctor immediately.

What is vitamin D Deficiency?

Vitamin D is a fat-soluble vitamin, and without sufficient levels, bones can become thin, brittle, or misshapen. The recommended amount of Vitamin D is not generally obtained by diet, but it can be made up for by exposure to sunlight and supplementation¹⁰. Low Vitamin D levels can cause fatigue, hair loss, muscle pain, and mood changes. Vitamin D works to help the body regulate and avoid these symptoms⁶,⁷,⁸.

Who should take a vitamin D home test?

Vitamin D deficiency generally affects older populations of people who do not get sufficient sun exposure or do not consume fortified foods. Gastrointestinal issues such as celiac disease can prevent Vitamin D from being absorbed by the intestines. The good news is that Vitamin D levels can be increased and within 9-12 months, most patients can return to appropriate levels.

What is vitamin D toxicity?

Vitamin D toxicity, also known as hypervitaminosis D, is the opposite of deficiency — occurring when you have excessive levels of the vitamin in your system. Though rare, this can cause serious health issues due to a buildup of calcium in the blood. Resulting symptoms can include nausea, vomiting, high frequency of urination, and a general feeling of weakness. Left untreated, dangerously high levels of Vitamin D can also lead to kidney and bone issues like calcium stones.

What’s the benefit of early testing?

Deficiency in vitamin D is associated with increased susceptibility to infection, so catching it early and making the necessary adjustments to lifestyle and nutrition can have strong preventative impact. Vitamin D levels have also been shown to strengthen your immune system¹⁰, helping to protect you from a number of common illnesses.

Vitamin D Monitoring Test FAQ's

What’s the normal range for vitamin D levels?

At least 25 ng/mL is in the normal level for 25-hydroxyvitamin D. However, too much vitamin d, above 60 ng/mL, can have adverse effects like nausea, vomiting or muscle weakness⁹,¹¹. If this test highlights that you are outside of the normal range of vitamin d levels, you can use the results report to engage a medical professional.

What will my results tell me?

The 25-hydroxyvitamin D biomarker is the best way to screen for and monitor vitamin D levels. Your results will tell you if you have low vitamin d, or if your vitamin d level is within the target range for adults. Based on these results, you will be able to see more clearly if you are deficient. Your results will help you talk to your physician about a treatment plan, which typically includes dietary changes, lifestyle improvements and supplementation.

Who should take this test?

Vitamin D is an important vitamin that supports bone density, insulin production and immune function. This test is ideal for those who:

  • Have osteoporosis or other bone-health problems
  • Work indoors and rarely spend time outside during the day¹
  • Have conditions that affect fat absorption, including celiac disease or weight-loss surgery¹²
  • Routinely take medications that interfere with vitamin D activity, including anticonvulsants and glucocorticoids
  • Adults that are age 60+¹,¹³
  • Are obese¹
  • Having a darker complexion¹

This test is also ideal for monitoring your vitamin d levels over time as you treat an existing deficiency.
