Vitamin A is a fat-soluble vitamin reported to facilitate eye, skin, immune system and other bodily functions and development. It was originally named "Fat-Soluble A", but renamed to "Vitamin A" in 1920.[4]
Vitamin A Deficiency and Toxicity
Vitamin A deficiency is very uncommon in the United States and other industrialized nations. Long-term deficiency may lead to dry eye and night blindness.[1,3]As it is a fat-soluble molecule, it's important to be highly aware of long-term accumulation and toxicity.[5]
Vitamin A is also antagonistic to vitamin D in animal models.[6]
Additionally, people with liver disease who also drink excessive amounts of alcohol may have a better chance of suffering liver damage from consuming vitamin A supplements.[1]
For these reasons, we express caution when discussing vitamin A supplements.
