The recognition and treatment of hypervitaminosis A.
The increasing incidence of vitamin A toxicity is related to vitamin A supplementation for unfounded reasons. This article describes the common symptomatology of vitamin A toxicity, including hypercalcemia, hepatomegaly, and dermatological and neurological effects. Retinol supplements, but not carotene supplements, become toxic when free retinol circulates. Responsibilities of health professionals include questioning vitamin use when taking health histories, educating themselves with scientifically based nutritional studies and applying RDAs (recommended daily allowances) when advising clients.
