                                Vitamin D toxicity, or hypervitaminosis D, is relatively uncommon but can be serious, with high levels of vitamin D leading to excessive calcium in the blood. The time it takes for vitamin D toxicity to clear can range from weeks to over a year, heavily depending on the severity of the overdose and how quickly treatment begins.
