About Vitamin D

Vitamin D fortifies the bones and plays supporting roles in the maintenance of your brain, pancreas, skin, muscles, reproductive organs and immune system. People between ages 19 and 24 need 10 mg every day and those 25 and older need 5 mg. If you spend enough time in the sun, you may not need any supplement. But if you're stuck inside that little cubby of an office for 80 or more hours a week and rarely emerge from your batcave on the weekend, you may want to look into getting some extra vitamin D.

Does the Sun give you vitamin D?

The RDA for this vitamin is rather low because your body is capable of making it with the help of sunlight. How do you get vitamin D from the sun? The body produces vitamin D from sunlight (specifically from the UVB band of ultraviolet light). Experts agree that moderate sun exposure is still the all natural, safest, most effective, and cost-free way to get your daily vitamin D. Also, the sun is needed to convert vitamin D into a form that the body can use.

The American Academy of Dermatology does not recommend getting vitamin D from sun exposure (natural) or indoor tanning (artificial) because ultraviolet (UV) radiation from the sun and tanning beds can lead to the development of skin cancer.
