According to Dr. Jacqueline Chan, increasing the surface of the skin exposed to the sun proportionately decreases the amount of time needed in the sun to produce the same amount of vitamin D. The duration of the sun exposure should be no more than about half the amount of time it takes for the skin to turn pink ( 38 ). Dr. Chan also says that in order to make vitamin D, "The sun must shine directly on skin without being blocked by sunscreen, glass and most plastics. Glass and most plastics block UVB, the part of the spectrum that converts pro-vitamin D3 but allow passage of UVA which contributes to skin cancer." ( 38 )

A 2008 study that was published in the American Medical Association's Archives of Internal Medicine was able to show that the risk of death from all causes can be decreased by 26 percent with vitamin D supplementation.  The study tracked 13,331 healthy people for nine years and correlated their causes of death and their vitamin D levels - it was found that those with the highest levels of vitamin D had a 26 percent lower chance of dying.  The researchers said "Our results make it much more clear that all men and women concerned about thier overall health should more closely monitor their blood levels of vitamin D, and make sure they have enough."

Certain people are more likely to have vitamin D deficiencies including: breast-fed infants, the elderly, people with dark skin tone, people living in latitudes far from the equator, those not eating a diet fortified with vitamin D, and those who are obese. In certain countries, clothing, for cultural dress or weather conditions can also limit the exposure to sunlight and thus to vitamin D. Even in sunny areas, those people who tend to work or play indoors, or wear sunscreen when outdoors, can have vitamin D levels that are too low.

Vitamin D is very important for strong bones. Calcium and phosphorus are essential for developing the structure and strength of your bones, and you need vitamin D to absorb these minerals. Even if you eat foods that contain a lot of calcium and phosphorus, without enough vitamin D, you can’t absorb them into your body. Vitamin D is important for general good health, and researchers now are discovering that vitamin D may be important for many other reasons outside of good bone health. Some of the functions of the body that vitamin D helps with include:
