What is the normal level of vitamin D in the blood?

What does a high vitamin D level in the blood mean?

A high level of vitamin D in the blood is not common but may occur due to excessive intake of vitamin D or high exposure to sunlight. However, it is often a result of long-term use of vitamin D supplements./p>

The vitamin D blood test usually measures only 25-hydroxy vitamin D [25(OH)D], which is the main circulating form of vitamin D.

Vitamin D [25(OH)D] blood values are usually given in ng/ml but sometimes you can see these values in nmol/l following the International System of Units (SI). In case your values are in nmol/l you can convert them using this tool:

nmol/L

A high vitamin D [25(OH)D] level in the blood means:

  • Moderate vitamin D increase (50 - 100 ng/ml in adults):

    The vitamin D level in the blood is slightly elevated. Vitamin D is produced through sunlight exposure, so levels can be higher in certain groups, such as surfers or lifeguards.

    It is advisable to monitor these levels in future blood tests and consult your doctor if you are taking vitamin supplements./p>

  • Severe vitamin D increase (> 100 ng/ml in adults) :

    The vitamin D level in the blood is very high, and it is necessary to reduce it to avoid serious health problems./p>

    A severe increase in vitamin D may cause symptoms such as nausea, anorexia, weakness, and constipation.

    Values over 150 ng/ml are considered toxic and may lead to hypercalcemia (high calcium concentration in the blood), hypercalciuria (excessive calcium excretion in urine), and suppression of parathyroid hormone (PTH), along with their related complications.

Which factors can raise the vitamin D level in the blood?

A vitamin D [25(OH)D] level in the blood higher than normal may be a sign of the following diseases:

  • Excessive sun exposure
  • Vitamin D intoxication
  • Drugs

Which diseases can raise your vitamin D level in the blood?

A vitamin D [25(OH)D] level in the blood higher than normal may be a sign of the following diseases:

  • Williams syndrome

    What can I do to lower the vitamin D level in the blood?

    Most cases of excessive vitamin D concentration in the blood are related to inappropriate use (such as unlicensed or poorly formulated supplements) or abuse of vitamin D supplements. If this is the case, you should stop taking vitamin D supplements, and if your doctor considers it necessary, reduce your dietary calcium intake.
