                                According to the National Institutes of Health, vitamin D toxicity can lead to gastrointestinal distress, including significant changes in stool. This is because excessive vitamin D elevates calcium levels in the blood, a condition called hypercalcemia, which disrupts normal digestive function. Understanding if and how vitamin D changes stool requires examining the impact of both deficiency and excessive intake on the digestive system.
