Vitamin A overdose



Introduction: Vitamin A overdose

Excessive Vitamin A intake usually occurs through consumption of large amounts of Vitamin A supplements. Vitamin A is used in the body for vision, immunity and bone and tissue growth and maintenance. Excessive Vitamin A use during pregnancy may increase the risk of birth defects. Vitamin A overdose can cause symptoms such as orange skin, blurred vision and nausea. Vitamin A toxicity can cause more severe symptoms such as growth retardation, hair loss and enlarged spleen and liver and even death. Retinol and beta carotene both belong to the Vitamin A family. The body automatically removes excess beta carotene so it is impossible to overdose on this type of Vitamin A.
