Vitamin D receptor (VDR)

The Vitamin D receptor (VDR) is a protein found in many cells of the body that acts like a switch to turn genes on or off. When vitamin D binds to VDR, it activates this switch, helping regulate processes like calcium absorption for healthy bones, immune function, and cell growth. VDR is essential for maintaining overall health, as it ensures the body responds properly to vitamin D levels. Without functioning VDR, the benefits of vitamin D may be diminished, leading to issues like weakened bones or immune problems.
