5 Facts About Vitamin D That You May Not Know

Posted by Rifki Hakim Tuesday, 15 January 2013


Vitamin D is an essential nutrient that is used to strengthen bones and prevent osteoporosis. Vitamin D is found in some foods such as salmon, milk, and eggs. Even so, there are many factors that influence the level of vitamin D in the body. Here are some things you do not know about vitamin D :

1. Place
The lower the climate of the region, the less sunlight reaching the earth's surface. For that, you will not get a lot of vitamin D from the sun if you live in a climate low. Not only that, the sun also can not give much vitamin D if you are wearing thick.

2. Air Condition
Researchers at Harvard Medical School said that the carbon particles from the burning of fossil fuels could destroy UVB rays in the air. But they also said that pollution causes the ozone hole can increase the production of vitamin D.

3. Use sunscreen
You can not get vitamin D from the sun if you use sunscreen. However, if the sunscreen is not used much, so vitamin D from the sun can still enter. It would be nice if used sunscreen during the daytime, to block the adverse effects of sunlight. While in the morning, you can sunbathe and get vitamin D without using sunscreen.

4. Skin color
Melanin is the substance that makes the skin look darker. This substance makes the skin does not absorb UVB sun rays. So if it takes a lot of vitamin D from the sun, people with darker skin need more time in the sun.

5. Weight
Body fat absorbs vitamin D, but could not remove it if it is needed. It makes people who are overweight have lower levels of vitamin D compared to those with normal weight. Not only that, the more a person gets older, the effects of vitamin D on the skin will decrease.

Those are some things you may not know about vitamin D and the factors that influence on your body. Hopefully this info is useful for the visitors. :)
