TLDR
It is suggested that vitamin D deficiency is unlikely in the two seasonal subpopulations of noninstitutionalized adolescents and adults that can be validly assessed in NHANES III and that insufficiency occurred fairly frequently in younger individuals, especially in the winter/lower latitude subsample.About:

Journal ArticleDOI
Estimation of optimal serum concentrations of 25-hydroxyvitamin D for multiple health outcomes
Heike A. Bischoff-Ferrari,Edward Giovannucci,Walter C. Willett,Thomas Dietrich,Bess Dawson-Hughes +4 more
TL;DR: Evidence from studies that evaluated thresholds for serum 25(OH)D concentrations in relation to bone mineral density, lower-extremity function, dental health, and risk of falls, fractures, and colorectal cancer suggests that an increase in the currently recommended intake of vitamin D is warranted.
Journal ArticleDOI
High prevalence of vitamin D inadequacy and implications for health.
TL;DR: The purposes of this article are to examine the prevalence of vitamin D inadequacy and to review the potential implications for skeletal and extraskeletal health.

The Role of Vitamin D and Calcium in Type 2 Diabetes. A Systematic Review and Meta-Analysis
TL;DR: Evidence from trials with vitamin D and/or calcium supplementation suggests that combined Vitamin D and calcium supplementation may have a role in the prevention of type 2 DM only in populations at high risk (i.e. glucose intolerance).
Journal ArticleDOI
Serum 25-hydroxyvitamin D levels and risk of multiple sclerosis
TL;DR: The results of this study suggest that high circulating levels of vitamin D are associated with a lower risk of multiple sclerosis.
Journal ArticleDOI
Hypovitaminosis D is associated with insulin resistance and β cell dysfunction
TL;DR: A positive correlation of 25(OH)D concentration with insulin sensitivity and a negative effect of hypovitaminosis D on beta cell function are shown, which are at higher risk of insulin resistance and the metabolic syndrome.

Effect of Calcium and Vitamin D Supplementation on Bone Density in Men and Women 65 Years of Age or Older
TL;DR: In men and women 65 years of age or older who are living in the community, dietary supplementation with calcium and vitamin D moderately reduced bone loss measured in the femoral neck, spine, and total body over the three-year study period and reduced the incidence of nonvertebral fractures.
Journal ArticleDOI
Influence of season and latitude on the cutaneous synthesis of vitamin D3: exposure to winter sunlight in Boston and Edmonton will not promote vitamin D3 synthesis in human skin.
TL;DR: The dramatic influence of changes in solar UVB radiation on cutaneous vitamin D3 synthesis is quantified and the latitudinal increase in the length of the "vitamin D winter" during which dietary supplementation of the vitamin may be advisable is indicated.
Journal ArticleDOI
Vitamin D supplementation, 25-hydroxyvitamin D concentrations, and safety
TL;DR: The assembled data from many vitamin D supplementation studies reveal a curve for vitamin D dose versus serum 25-hydroxyvitamin D [25(OH)D] response that is surprisingly flat up to 250 microg (10000 IU) vitamin D/d.

Melissa K. Thomas,Donald M. Lloyd-Jones,Ravi Thadhani,Albert C. Shaw,Donald J. Deraska,Barrett T. Kitch,Eleftherios C. Vamvakas,Ian M. Dick,Richard L. Prince,Joel S. Finkelstein +9 more
TL;DR: Hypovitaminosis D is common in general medical inpatients, including those with vitamin D intakes exceeding the recommended daily allowance and those without apparent risk factors for vitamin D deficiency.
