Taking 200 percent of the amount of Vitamin A you need in a day may result in vitamin A toxicity.This excess amount of vitamin A is stored in the liver, accumulates with time. Acute or chronic toxicity of vitamin A results in several complications such as damaged kidneys and liver, and also causes changes in vision.
When taking more vitamin A than you need in your body, it accumulates and leads to what is known as hypervitaminosis. Hypervitaminosis can be either acute toxicity or chronic toxicity depending on the period of taking the excess vitamin A. It is acute if it is over a small period of time and it is chronic if it is over a long period of time. This toxicity has symptoms of liver damage, increased pressure on the brain and sometimes causes death.
