What Does Vitamin D Do in the Body?

<image4>

Vitamin D is a key nutrient that does many important things in our bodies. It’s not just for bones; it affects many other body functions too.

Vitamin D Metabolism and Activation

Vitamin D starts its journey in our bodies when we eat it or make it in our skin from sunlight. It first gets changed in the liver to 25-hydroxyvitamin D [25(OH)D]. This is the main form that circulates in our blood.

Then, it goes to the kidneys, where it turns into its active form, 1,25-dihydroxyvitamin D [1,25(OH)2D], or calcitriol.

Key steps in vitamin D metabolism include:

• Hydroxylation in the liver to form 25(OH)D
• Renal conversion to the active form, 1,25(OH)2D
• Regulation by parathyroid hormone (PTH) and fibroblast growth factor 23 (FGF23)

Cellular Mechanisms of Action

The active vitamin D, 1,25(OH)2D, works by binding to the vitamin D receptor (VDR) in many cells. This binding starts a chain of signals inside the cell that changes how genes work.

The VDR is a nuclear receptor that controls the transcription of target genes. When it binds to 1,25(OH)2D, the VDR teams up with the retinoid X receptor (RXR) and moves to the nucleus. There, it helps control the genes involved in many body processes.

Gene Expression Regulation

Vitamin D has a big impact on gene expression, affecting cell growth, differentiation, and death. It helps keep tissues healthy and prevents diseases by controlling gene expression.

Some key areas where vitamin D influences gene expression include:

1. Cell cycle regulation
2. Apoptosis and cell survival
3. DNA repair mechanisms
4. Immune response modulation

Understanding how vitamin D works at a molecular level helps us see its importance for health and disease prevention.

Different Forms of Vitamin D: D2 vs D3
