Think about vitamin D when you’re catching up on summer rays. It’s sometimes called the “sunshine vitamin” because it’s produced in your skin in response to sunlight. Vitamin D is a fat-soluble (脂溶性的) vitamin in a family of compounds that includes vitamins D-1, D-2, and D-3. It can affect as many as 2,000 genes in the body.

Vitamin D has several important functions. Perhaps the most vital are regulating the absorption of calcium and phosphorous(磷), and promoting normal immune system function. Getting enough vitamin D is important for normal growth and development of bones and teeth, as well as improving resistance against certain diseases.

In addition to its primary benefits, research suggests that vitamin D may also play a role in:

reducing your risk of multiple sclerosis(多发性硬化), according to a 2006 study published in the Journal of the American Medical Association

decreasing your chance of developing heart disease, according to 2008 findings published in Circulation

helping to reduce your possibility of developing the flu, according to 2010 research published in the American Journal of Clinical Nutrition

regulating mood and warding off depression

losing weight or preventing heart disease

How do you get it? Your body produces vitamin D naturally when it is directly exposed to sunlight. A little can go a long way. All you need is 10 minutes a day of midday, pre-sunscreen sun exposure,especially if you have fair skin. Besides getting vitamin D through sunlight, you can also get it through certain foods and supplements to ensure adequate levels of the vitamin in your blood.
