Vitamin A (Retinol) daily dose

Vitamin A plays a role in healthy vision, bone and tissue growth, and reproduction. It also helps regulate your immune system, which prevents and fights infections.
Although your body can convert plant sources of beta carotene into vitamin A, animal sources of vitamin A are better absorbed. So, if you’re a vegetarian who relies on fruits and vegetables to meet your daily vitamin A requirements, you need to eat at least five daily servings of these foods. Vitamin A deficiency is rare in the United States, but people with certain diseases, such as celiac disease, Crohn’s disease or pancreatic disorders, may have trouble absorbing the vitamin and need supplements. Dietary intake studies
suggest an association between diets rich in beta carotene and vitamin A and a lower risk of some types of cancer. However, if too much vitamin A is stored in the body, it may increase the risk of birth defects, liver abnormalities and reduced bone mineral density — which could lead to osteoporosis. Research has also found that beta carotene, taken in supplement form, can be dangerous. In several recent studies, smokers and former smokers who took beta carotene had an increased risk of lung cancer. It’s not possible, however, to get too much beta carotene from foods.
