Diets rich in beta-carotene have been associated in studies with a lower incidence of some malignancies such as Hodgkin’s lymphoma and cancers of the bladder, cervix and lung. But rather than animal-based forms of vitamin A this protective effect is mostly linked to plant-based sources. It’s interesting to note that although vitamin A produced from plants may reduce the risk of cancer supplements may raise the risk of other malignancies such as lung cancer particularly in smokers.
3. Supports a Healthy Immune System

5. Supports Bone Health
Vitamin A is crucial for the formation and maintenance of bones in addition to calcium vitamin D and protein which are important nutrients for sustaining bone health. An increased risk of fractures is associated with low levels of vitamin A while appropriate intake may lower this risk. On the other hand, some research suggests that fractures could result from abnormally elevated vitamin A levels. There is probably more than one element that affects the intricate link between vitamin A and bone health such as the presence of vitamin D.
6. Promotes Healthy Growth and Reproduction
The appropriate growth of embryos during pregnancy and the health of the reproductive system depend on vitamin A. According to research on animals a vitamin A shortage can impact egg quality and sperm production leading to infertility in both males and females. This vitamin aids in the development of vital organs such as the heart, lungs and nervous system during pregnancy. Pregnant women are advised to avoid foods high in vitamin A, such as liver and some supplements as overindulging in this vitamin might result in birth abnormalities.
