Vitamin D Deficiency

Vitamin D deficiency , or hypovitaminosis D , most commonly results from inadequate sunlight exposure in particular sunlight with adequate ultraviolet B rays. It can also worsen osteomalacia and osteoporosis in adults, leading to an increased risk of bone fractures. Ultraviolet B rays from sunlight is a large source of vitamin D. Fatty fish such as salmon , herring , and mackerel are also sources of vitamin D. Milk is often fortified with vitamin D and sometimes bread, juices, and other dairy products are fortified with vitamin D as well.
Vitamin D helps your body absorb calcium. Calcium is one of the main building blocks of bone. Vitamin D also has a role in your nervous, muscle, and immune systems. You can get vitamin D in three ways: through your skin, from your diet, and from supplements. Your body forms vitamin D naturally after exposure to sunlight.
Vitamin D is an extremely important vitamin that has powerful effects on several systems throughout your body 1. Unlike other vitamins, vitamin D functions like a hormone, and every single cell in your body has a receptor for it. It's also found in certain foods such as fatty fish and fortified dairy products, though it's very difficult to get enough from diet alone.

Recent evidence for the nonskeletal effects of vitamin D, coupled with recognition that vitamin D deficiency is common, has revived interest in this hormone. Vitamin D is produced by skin exposed to ultraviolet B radiation or obtained from dietary sources, including supplements. Persons commonly at risk for vitamin D deficiency include those with inadequate sun exposure, limited oral intake, or impaired intestinal absorption. Vitamin D adequacy is best determined by measurement of the hydroxyvitamin D concentration in the blood. Average daily vitamin D intake in the population at large and current dietary reference intake values are often inadequate to maintain optimal vitamin D levels. Clinicians may recommend supplementation but be unsure how to choose the optimal dose and type of vitamin D and how to use testing to monitor therapy.

Vitamin D deficiency: Symptoms, causes, and prevention
Vitamin D deficiency — when the level of vitamin D in your body is too low — can cause your bones to become thin, brittle or misshapen. Vitamin D also appears to play a role in insulin production and immune function — and how this relates to chronic disease prevention and cancer — but this is still being investigated. Although the amount of vitamin D adults get from their diets is often less than what's recommended, exposure to sunlight can make up for the difference. For most adults, vitamin D deficiency is not a concern. However, some groups — particularly people who are obese, who have dark skin and who are older than age 65 — may have lower levels of vitamin D due to their diets, little sun exposure or other factors.
