About Vitamin A
Vitamin A is a fat-soluble antioxidant that protects your cells against damaging free radicals and plays other vital roles in the body. However, it is potentially more dangerous than most other vitamins because it can build up to toxic levels. For this reason, it should be used with caution.
It has long been assumed that beta-carotene supplements taken at nutritional doses are a safer way to get the vitamin A you need. However, while this may be true in general, beta-carotene also appears to present some risks. See the full Beta-Carotene article for more information.
Vitamin A is an essential nutrientómeaning you must get it in the diet.
We get vitamin A from many foods, in the form of either vitamin A or beta-carotene. Liver and dairy products are excellent sources of vitamin A. Carrots, apricots, collard greens, kale, sweet potatoes, parsley, and spinach are good sources as well.
Warning: Pregnant women should not take vitamin A supplements. Instead they should take beta-carotene.
