Abstract
There has been a recent resurgence of media attention and research on the topic of Vitamin D due to an increased prevalence of deficiency. Thus leading to the question, is the current Daily Recommended Intake (DRI) enough? This review will be examining evidence based research articles in the scientific literature (peer reviewed) regarding the adequacy of current recommendations for Vitamin D intake to maintain normal levels in the blood and the recommended intake to restore deficient levels of Vitamin D to normal range. Additional detailed background information on the mechanisms of the activation of Vitamin D, effects of Vitamin D deficiency, measurements of Vitamin D status in the blood, and the current recommendations for Vitamin D intake is also discussed. The literature review indicates that the current DRI (5ug/d or 200 IU) to maintain normal levels is not sufficient and does in fact needs to be increased to 800-1000 IU (20 ug-25 ug). Once Vitamin D deficient, there were conflicting recommendations in the scientific literature as to the dose needed and the length of treatment to restore blood levels back to normal. Further research is indicated regarding this topic.
