VITAMIN D

Vitamin D is also known as the sunshine vitamin for ages. And it’s indeed the sunshine of your health because it targets more than one area of your body’s health. Vitamin D plays a vital role in bones and teeth, the immune system, brain health, and regulating inflammation.
In this article, we will cover the types of vitamin D, its role and sources, and what happens to the body when people do not get enough of these vitamins.

VITAMIN D

Vitamin D is a fat-soluble vitamin that is important for good health. It is responsible for strong bones and teeth. It helps your body absorb calcium, one of the main building blocks for strong bones. Together with calcium, vitamin D helps protect your body from developing osteoporosis.
As I have mentioned above the word “sunshine” for Vitamin D is quite appropriate because as the name suggests its production can be triggered by exposure to sun. Apart from this vitamin D can also be obtained from red meat, egg yolks, and fatty fish like tuna and mackerel.

TYPES OF VITAMIN D

There are two forms of vitamin D, which are D2, also known as ergocalciferol, and D3, also known as cholecalciferol.

VITAMIN D3

According to the National Institute of Health’s Office of Dietary Supplements, researchers are not sure yet if one is better than the other for human health as both Vitamin D2 and Vitamin D3 play the same role in the body, but are different in molecular structures.

How much daily vitamin D should one take?

Based on the Dietary Reference Intakes (DRIs) developed by expert committees of NASEM, the recommended intake of Vitamin D for different age groups and genders are as follows:

NOTE: In case of pregnancy and lactation period in women between 14-18 years, it recommends 15 mcg (600 IU) and 15 mcg (600 IU). Whereas, in women between 19 and 50 years age group, it suggests 15 mcg (600 IU) and 15 mcg (600 IU).
