Vitamin D is an important nutrient that plays a number of important roles in the body. It is needed for proper growth and development of bones and teeth, and it helps the body absorb calcium, which is necessary for healthy bones. Vitamin D is also important for the immune system and can help reduce the risk of certain diseases such as osteoporosis, cancer and multiple sclerosis. It can also help regulate blood pressure and improve muscle function.

This test detects a possible vitamin D deficiency or whether you have normal or elevated vitamin D levels. It gives you insight into your values and whether any symptoms you experience may be due to vitamin D deficiency. By testing yourself, you get a good insight into your values if you need to make any changes in your lifestyle to increase or decrease your levels of vitamin D.

Vitamins and minerals are essential nutrients that the body needs to maintain normal function, energy metabolism and immune function. They play a central role in everything from blood formation and bone health to hormone production and nerve function. Vitamin and mineral analyses are performed on the blood to identify any deficiencies or imbalances. They can provide important information about nutritional status and help optimize health through personalized dietary and supplement recommendations.

To activate your referral, simply follow the instructions that you will receive via email after completing the purchase. The email contains an activation code, by clicking on the link in the email you enter the flow to fill in any information, activate the referral and select reception in the sample answer service zample.

Before the sampling

  • Rest for 15 minutes in place on the sampling unit.
  • Bring valid identification.

The referral is available digitally at the sampling unit after you activate it, follow the instructions you receive via email. Here you can read our guidelines before taking samples.

Common symptoms of vitamin D deficiency include fatigue, weak muscles, joint and bone pain, depression, and a weakened immune system. A blood test can provide a clear answer to your vitamin D levels and whether you need supplements or changes to your habits.

The blood test measures the level of 25-hydroxyvitamin D (25(OH)D) in the blood, which is the form that best reflects the body's vitamin D levels. The test is taken through a simple venous blood sample, and you do not need to fast beforehand.

Optimal levels of 25(OH)D in the blood are usually between 100–175 nmol/L but can vary. Values ​​below 50 nmol/L are often considered a sign of deficiency, while levels above 220 nmol/L may indicate an excess, especially when supplementing.

Yes, taking too much vitamin D through supplements can lead to vitamin D poisoning with symptoms such as nausea, high blood calcium levels and kidney problems. The recommended daily intake should not be exceeded without medical advice.

The answer is highly individual, but during the summer most people get enough vitamin D from the sun in the north, but during the autumn and winter supplements are recommended to maintain a healthy level. Note that the need is individual and a blood test will help you determine if supplements are needed year-round.

The speed at which vitamin D levels rise depends on initial deficiency, supplement dosage, and individual absorption. With daily recommended doses, levels typically begin to improve within a few weeks, but it can take 2–3 months to reach optimal levels. In some cases, higher initial doses are used for faster correction, always under medical supervision.

Yes, research shows that vitamin D plays an important role in brain function and can influence mood. Low vitamin D levels have been linked to feelings of sadness and an increased risk of depression, especially in winter. Adequate vitamin D intake may support mental well-being and reduce symptoms like fatigue and low energy.

Long-term vitamin D deficiency reduces the body’s ability to absorb calcium, leading to weaker bones and an increased risk of osteoporosis. Children may develop rickets, while adults are at risk of osteomalacia (soft bones). Other symptoms include fatigue, muscle weakness, and a weakened immune system, making you more susceptible to infections.
