VDR (Vitamin D Receptor)

The Vitamin D Receptor (VDR) is a protein found inside our cells that acts like a switch. When vitamin D binds to VDR, it activates the receptor, allowing it to regulate the expression of genes involved in bone health, immune response, and other essential functions. Think of VDR as a messenger that interprets vitamin D signals and helps coordinate how our body responds to ensure proper maintenance, growth, and defense against illnesses. Proper functioning of VDR is vital for maintaining overall health, especially in bone strength and immune system regulation.
