Vitamin D: The Sunshine Vitamin

What is Vitamin D?

Vitamin D is a fat-soluble vitamin that plays a crucial role in maintaining healthy bones, immune function, and cardiovascular health. It is often referred to as the "sunshine vitamin" because it can be produced in the skin upon exposure to sunlight.

How Does Vitamin D Work?

Vitamin D from dietary intake or sun exposure requires two activation steps in the body. The first activation occurs in the liver, while the second activation occurs in the kidneys, allowing for regulation of calcium metabolism. However, vitamin D receptors are present throughout the body, in tissues such as the skin, cartilage, heart, prostate, bones, and intestines. This means that the second activation step also takes place in local tissues.

Benefits of Vitamin D

• Immune Function: Vitamin D enhances and regulates immune function by influencing the expression of cytokines, which are chemical messengers of the immune system.
• Cardiovascular Health: Vitamin D supports optimal cardiovascular function by modulating the growth and proliferation of heart cells and blood vessels.
• Cellular Function: Vitamin D enhances cellular function by inhibiting the release of proteins that can be detrimental to cell function.
