    form of vitamin D measured in blood to assess status

    25-Hydroxyvitamin D, also known as 25(OH)D or Calcifediol, is a form of vitamin D that is measured in the blood to assess a person's vitamin D status. It is produced in the liver from vitamin D3 (cholecalciferol) and is a crucial indicator because it reflects the total amount of vitamin D from both dietary intake and sunlight exposure.
