Abstract
Vitamin A is a commonly available supplement found naturally in many foods. While it is essential for numerous physiological processes, caution is required when supplementing at high doses, as excessive intake can result in vitamin A toxicity, which may present with hypercalcemia. We report a case of a patient who developed elevated calcium levels associated with excessive vitamin A consumption. This case highlights the importance of considering inappropriate vitamin A supplementation as a potential cause of hypercalcemia.
