Summary

Vitamin D insufficiency is an increasing trend in the United States. According to the NHANES data collection there was a near doubling of patients with vitamin D deficiency in 10 years. Vitamin D deficiency is associated with several adverse outcomes such as increased fractures, certain microbial diseases, cardiovascular diseases, and metabolic dysfunction. The increasing prevalence of vitamin D deficiency has been attributed to the increasing prevalence of obesity. Several studies have shown that obese patients have lower 25-OH vitamin D (25-OHD) levels compared to nonobese patients and obese patients require more vitamin D compared to nonobese patients. The most commonly prescribed medication to replete vitamin D deficiency is oral ergocalciferol. To date, no prospective trials have been published to evaluate a standard protocol in the treatment of vitamin D insufficiency in adults.
