Vitamin D, 1, 25-Hydroxy Test results are positively correlated with DNA methylation. DNA methylation is a mechanism used by cells to regulate gene expression. Vitamin D3 supplementation increases DNA methylation in a dose-response manner in persons with vitamin D deficiency.
Maternal vitamin D status plays a role in determining DNA methylation state in the germline of successive generations. Detection of methylation changes in the unexposed second-generation demonstrates that maternal vitamin D depletion can have long-term effects on the epigenome of subsequent generations. 
Vitamin D, also known as the sunshine vitamin, is produced by the body as a response to sun exposure; it can also be consumed in food or supplements.

Vitamin D has multiple roles in the body, helping to:

    • Maintain the health of bones and teeth.
  • Support the health of the immune system, brain, and nervous system.
  • Regulate insulin levels and aid diabetes management.
  • Support lung function and cardiovascular health.
  • Influence the expression of genes involved in cancer development.
Vitamin D is actually not a vitamin.

Despite the name, vitamin D is considered a pro-hormone and not actually a vitamin. Vitamins are nutrients that cannot be created by the body and therefore must be taken in through our diet. However, vitamin D can be synthesized by our body when sunlight hits our skin. It is estimated that sensible sun exposure on bare skin for 5-10 minutes 2-3 times per week allows most people to produce sufficient vitamin D, but vitamin D breaks down quite quickly, meaning that stores can run low, especially in winter.

Recent studies have suggested that a substantial percentage of the global population is vitamin D deficient.

General Use

Rule out vitamin D deficiency

Methodology

Immunochemiluminometric assay (ICMA). This assay is performed on the DiaSorin LIAISON® instrument in multiple laboratories throughout LabCorp. This highly automated test measures both D2 and D3 together and reports a total 25-hydroxy vitamin D.
