What can happen if too much vitamin A is consumed?
“Hypervitaminosis A” (from the Greek “hyper”—too much) causes symptoms such as loss of appetite, blurred vision, headache, muscle soreness, loss of hair, redness and peeling of the skin. A healthy non-pregnant adult may safely consume up to 10 times the RNI for this vitamin. Pregnant women should limit supplementation to 8,000 IU/day. The recommended amounts of vitamin A from a mixed diet together with supplements of 8,000 IU/day are considered well within the safety margin for this vitamin.
