Does beta-carotene destroy cancer cells?
These carotenoids also increase carcinogen-metabolizing enzymes and stimulate self-destruction of abnormal cells. The body uses beta-carotene and alpha-carotene to form vitamin A, which helps protect against cancer through the immune system and expression of genes that regulate cell growth.
What is a serious problem with beta-carotene supplements?
