Clinical vignette: A 68-year-old woman consults you after a recent bone mineral density screening revealed osteopenia, total hip T score of –1.8. Further evaluation shows her only other abnormal lab value is a serum 25-hydroxyvitamin D [25(OH)D] level of 13 ng/ml (normal 30–80). You find no evidence of malabsorption. What vitamin D supplement regimen should you recommend to reduce her risk of fractures?

Usage data is cumulative from February 2019 through February 2020.
Usage information is collected from two different sources: this site (JCI) and Pubmed Central (PMC). JCI information (compiled daily) shows human readership based on methods we employ to screen out robotic usage. PMC information (aggregated monthly) is also similarly screened of robotic usage.
Various methods are used to distinguish robotic usage. For example, Google automatically scans articles to add to its search index and identifies itself as robotic; other services might not clearly identify themselves as robotic, or they are new or unknown as robotic. Because this activity can be misinterpreted as human readership, data may be re-processed periodically to reflect an improved understanding of robotic activity. Because of these factors, readers should consider usage information illustrative but subject to change.
