As vitamin A is fat-soluble, disposing of any excesses taken in through diet is much harder than with water-soluble vitamins B and C. As such, vitamin A toxicity can result. This can lead to nausea, jaundice, irritability, anorexia (not to be confused with anorexia nervosa, the eating disorder), vomiting, blurry vision, headaches, muscle and abdominal pain and weakness, drowsiness and altered mental status.

Answer 2

Hypervitaminosis A, or vitamin A toxicity can occur in the short, or long term use. Short term toxicity can present with cracked dry skin, nausea, fatigue, headache, dizziness, and swelling of the brain. If the toxicity occurs from taking vitamin over a longer period of time you may see all of the above along with psychiatric changes, anorexia, coma, bone and joint pain, and even hip fractures.
