What is Vitamin D?

Vitamin D is a fat-soluble vitamin that is naturally present in very few foods, added to others, and available as a dietary supplement. It is also produced endogenously when ultraviolet rays from sunlight strike the skin and trigger vitamin D synthesis.

Vitamin D Deficiency

Naturally our bodies produce the necessary Vitamin D needed. However, this production only happens when our skin is exposed to sufficient sunlight and only under the right conditions. The right sunlight is also dependent upon several factors including season, geographic latitude, time of day, cloud cover, and sunscreen. Finding that ideal situation is difficult and not practical, which is why so many people are Vitamin D deficient.

Vitamin D deficiency, which is often seen in post-menopausal women and older Americans, has been associated with greater incidence of hip fractures. In a review of women with osteoporosis hospitalized for hip fractures, 50 percent were found to have signs of vitamin D deficiency. Daily supplementation with 20 800 IU of vitamin D may reduce the risk of osteoporotic fractures in elderly populations with low blood levels of vitamin D. The Decalyos II study examined the effect of combined calcium and vitamin D supplementation in a group of elderly women who were able to walk indoors with a cane or walker. The women were studied for two years, and results suggested that such supplementation could reduce the risk of hip fractures in this population.

Rickets and osteomalacia are classic vitamin D deficiency diseases. In children, vitamin D deficiency causes rickets, which results in skeletal deformities. In adults, vitamin D deficiency can lead to osteomalacia, which results in muscular weakness in addition to weak bones. Populations who may be at a high risk for vitamin D deficiencies include the elderly, obese individuals, exclusively breastfed infants, and those who have limited sun exposure. Also, individuals who have fat malabsorption syndromes (e.g., cystic fibrosis) or inflammatory bowel disease (e.g., Crohn's disease) are at risk.

Older Americans (greater than age 50) are thought to have a higher risk of developing vitamin D deficiency. The ability of skin to convert vitamin D to its active form decreases as we age. The kidneys, which help convert vitamin D to its active form, sometimes do not work as well when people age. Therefore, some older Americans may need vitamin D from a supplement.

It is important for individuals with limited sun exposure to include good sources of vitamin D in their diets. Homebound individuals, people living in northern latitudes such as in New England and Alaska, women who cover their body for religious reasons, and individuals working in occupations that prevent exposure to sunlight are at risk of a vitamin D deficiency. If these individuals are unable to meet their daily dietary need for vitamin D, they may need a supplement of vitamin D.

Vitamin D Benefits

Vitamin D is an important part of a healthy diet. New benefits of this vitamin are being discovered every day, but many people still do not receive enough vitamin D to reap the wonderful benefits it can provide to their health.

Vitamin D is most famous for its contribution to joint and bone health by helping the body absorb calcium. It has been shown that people who take in enough vitamin D are less likely to suffer from osteoporosis and joint pain. This vitamin can also slow the affects of arthritis and lessen back pain in many individuals. Studies have shown that vitamin D can also prevent certain types of cancer.

Vitamin D is one of the only vitamins produced naturally by the body. However, in order for the body to produce vitamin D, it has to be exposed to an adequate amount of sunlight. Generally, an hour per week is more than enough, but surprisingly, many people are still not exposed to enough sun to produce beneficial amounts of vitamin D. Also, studies have shown that as we age, we tend to produce less vitamin D even with adequate sun exposure. These are the primary reasons why many adults have to monitor their diets to make sure they are taking in enough vitamin D.

While it is important to have enough vitamin D in your diet, it is possible to take in too much vitamin D. This often happens when a person receives a good amount of sun exposure and consumes many foods that contain moderate amounts of vitamin D, but also continues to take a vitamin D supplement. For this reason, it is important to discuss with your doctor whether or not you require a vitamin D supplement as part of your diet.
