TY - JOUR T1 - Risks of the ‘Sunshine pill’ – a case of hypervitaminosis D JF - Clinical Medicine JO - Clin Med SP - 311 LP - 313 DO - 10.7861/clinmedicine.18-4-311 VL - 18 IS - 4 AU - Sebastien Ellis AU - Georgios Tsiopanis AU - Tanuj Lad Y1 - 2018/08/01 UR - http://www.rcpjournals.org/content/18/4/311.abstract N2 - Vitamin D is a fat-soluble vitamin essential for calcium homeostasis and bone health. Vitamin D toxicity or hypervitaminosis D is extremely rare. We describe the case of a 73-year-old man who presented with life-threatening hypervitaminosis D and hypercalcaemia resulting from self-medicated doses of vitamin D supplements. This case, alongside other global case reports, highlights the potential dangers of unlicensed vitamin D replacement. We discuss the evidence for vitamin D replacement and remind readers of the current guidance on daily intake and supplementation. ER -
