About Beta Carotene:

　　Beta-carotene is the main safe dietary source of vitamin A. Vitamin A is essential for normal growth and development, immune system function, and vision.
　　Beta-carotene can quench singlet oxygen, a reactive molecule that is generated, for instance, in the skin by exposure to ultraviolet light, and which can induce precancerous changes in cells. Singlet oxygen is capable of triggering free radical chain reactions.
　　Beta-carotene has antioxidant properties that help neutralise free radicals – reactive and highly energised molecules which are formed through certain normal biochemical reactions （e.g. the immune response, prostaglandin synthesis）, or through exogenous sources such as air pollution or cigarette smoke. Free radicals can damage lipids in cell membranes as well as the genetic material in cells, and the resulting damage may lead to the development of cancer.
