Vitamin D Blood Test

  • Worldwide, an estimated one billion people have inadequate levels of vitamin D in their blood, and deficiencies can be found in all ethnicities and age groups’ (Harvard School of Public Health, 2012). It is important to know your vitamin D level and supplement according to your individual needs.
  • Strong bones and muscles, mental fitness, prevention of osteoporosis and athletic performance are just a few of the benefits that are linked to healthy vitamin D levels in countless scientific studies.
  • Young adults, seniors, and women all especially need to keep their vitamin D level in mind because they are at higher risk.

  • Unfortunately, vitamin D deficiency can not be tasted’ or felt’. Therefore, it is important to test your levels regularly.

The cerascreen Vitamin D Test is a sample kit for at-home use. The test is used to determine your blood concentration of vitamin D and to monitor the level of 25-OH vitamin D. The Vitamin D Test includes a free return envelope and evaluation in our diagnostics laboratory as well as a detailed results report. Receive your results within one to two working days after sample arrival.

Vitamin D is a year-round issue

Due to diet and lack of sunlight, vitamin D concentration in many people is often less than 31 nanograms per millilitre (ng/ml) and thus below the minimum concentration recommended by physicians. On the other hand, experts in orthomolecular medicine recommend a healthy level of between 40 and 60 nanograms per millilitre as the target for optimal and preventive care.

One should check their vitamin D level several times a year!
Quickly and easily determine if and to what extent you lack the essential vitamin D!


The Cerascreen Vitamin D Test makes determining your vitamin D levels fast and easy. You send a few drops of blood from your fingertip to our specialised laboratory, where we take care of the professional analysis and individual evaluation. Based on the test results, our nutrition experts will determine your personal vitamin D supplementation plan.

Vitamin D is generally considered a feel-good vitamin and supports more than 30 important bodily functions. But since vitamin D is primarily formed by the skin’s direct exposure to sunshine, the vast majority of people are not sufficiently supplied with vitamin D! Additionally, many people have a nutritional condition that prevents them from absorbing and storing vitamin D properly.
