There is scientific debate about how much vitamin D people need each day and what the optimal serum levels should be to prevent disease. In industrialized countries, doctors are seeing the resurgence of rickets, the bone-weakening disease that had been largely eradicated through vitamin D fortification. Worldwide, an estimated 1 billion people have inadequate levels of vitamin D in their blood, and deficiencies can be found in all ethnicities and age groups. NHANES data found that the median intake of vitamin D from food and supplements in women ages 51 to 71 years was 308 IU daily, but only 140 IU from food alone (including fortified products). Many people may not be meeting the minimum requirement for the vitamin. The UL for vitamin D for adults and children ages 9+ is 4,000 IU. UL: The Tolerable Upper Intake Level is the maximum daily intake unlikely to cause harmful effects on health. RDA: The Recommended Dietary Allowance for adults 19 years and older is 600 IU daily for men and women, and for adults >70 years it is 800 IU daily. The Recommended Dietary Allowance for vitamin D provides the daily amount needed to maintain healthy bones and normal calcium metabolism in healthy people.

Also, people with darker skin tend to have lower blood levels of vitamin D because the pigment (melanin) acts like a shade, reducing production of vitamin D (and also reducing damaging effects of sunlight on skin, including skin cancer). Vitamin D production in the skin is the primary natural source of vitamin D, but many people have insufficient levels because they live in places where sunlight is limited in winter, or because they have limited sun exposure due to being inside much of the time. Both are also naturally occurring forms that are produced in the presence of the sunвЂ™s ultraviolet-B (UVB) rays, hence its nickname, вЂњthe sunshine vitamin,вЂќ but D2 is produced in plants and fungi and D3 in animals, including humans.

Vitamin D supplements are available in two forms: vitamin D2 (вЂњergocalciferolвЂќ or pre-vitamin D) and vitamin D3 (вЂњcholecalciferolвЂќ). For most people, the best way to get enough vitamin D is taking a supplement because it is hard to eat enough through food. Many of the bodyвЂ™s organs and tissues have receptors for vitamin D, which suggest important roles beyond bone health, and scientists are actively investigating other possible functions.ДЇew foods naturally contain vitamin D, though some foods are fortified with the vitamin. Also, laboratory studies show that vitamin D can reduce cancer cell growth, help control infections and reduce inflammation. It is a fat-soluble vitamin that has long been known to help the body absorb and retain calcium and phosphorus both are critical for building bone. Vitamin D is both a nutrient we eat and a hormone our bodies make.
