Hypervitaminosis A refers to the toxic condition caused by an excessive amount of Vitamin A in the body. Since Vitamin A is fat-soluble, it is stored in the liver, and consuming it in high doses over time can lead to its accumulation and toxicity. There are two forms of Vitamin A: preformed Vitamin A (retinol and retinyl ester), found in animal products, and provitamin A (beta-carotene and other carotenoids), found in plant-based foods. Toxicity typically arises from excessive intake of preformed Vitamin A.
