Despite its name, vitamin D is not a regular vitamin. It's actually a steroid hormone that you get primarily from either sun exposure or supplementation, and its ability to influence genetic expression that produces many of its wide-ranging health benefits.
Researchers have pointed out that increasing levels of vitamin D3 among the general population could prevent chronic diseases that claim nearly one million lives throughout the world each year. Incidence of several types of cancer could also be slashed in half.
Vitamin D also fights infections, including colds and the flu, as it regulates the expression of genes that influence your immune system to attack and destroy bacteria and viruses.
More health benefits of Vitamin D:
- Regulating absorption of calcium & phosphorous
- Important for normal growth & development of bones and teeth
Vitamin D-ficiency can be caused by:
- Pollution
- Sunblock
- Spending more time indoors
- Working longer hours in offices
- Living in big cities where tall buildings block sunlight
Because of these factors, it is sometimes necessary to get your Vitamin D from other sources, like supplements or fortified foods.
