Understanding Vitamin D

How Much Important is Vitamin-D?

Understanding the importance of Vitamin D, its role in the body, and why maintaining adequate Vitamin D levels matters.

Nuts and Bolts of Vitamin D

Vitamin D Basics

Why is Vitamin D Important?

Vitamin D, often described as the “Sun Vitamin”, has hormone-like activity and is involved in many important functions within the body.

  • Vitamin D3 is produced in the skin when it is exposed to ultraviolet radiation from sunlight.
  • Vitamin D can also be obtained through food and Vitamin D supplements.
  • A significant proportion of Vitamin D is produced through sunlight exposure, while the natural diet generally contains relatively little Vitamin D.
  • Vitamin D status therefore depends on sunlight exposure as well as dietary and supplemental intake.

Vitamin D Receptors

Vitamin D Receptors

Vitamin D receptors, also known as VDR, are found across many tissues and important organs throughout the body. They allow Vitamin D signals to influence cellular processes.

  1. 01

    Vitamin D receptors are widely distributed throughout the body's tissues and organs.

  2. 02

    These receptors enable cells to respond to Vitamin D signals.

  3. 03

    Vitamin D receptor signalling is involved in regulating functions across different tissues.
