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

A high value of vitamin D in the blood is not common, but may be seen in case of a high intake of vitamin D or a high exposure to the sunlight. However, many times it is due to an excessive long-term use of supplements containing vitamin D.

The vitamin D blood test usually measures only the 25-hydroxy vitamin D [25(OH)D] that it 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:


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 a bit high. Vitamin D is produced by exposure to sunlight. As a result, it can be increased in some groups such as surfers or lifeguards.

    It is advisable to monitor the level in future blood tests and visit your doctor in case you are taking vitamin supplements.

  • 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 in order to avoid serious health problems.

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

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

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:

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