How much vitamin D should I take?
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?
