Vitamin A supports the proper functioning of the heart, lungs, kidneys, and immune system. You want that, right? But a quarter of Americans consume less than half the recommended daily allowance (RDA) of vitamin A, which is already set too low by the US Food and Drug Administration. Many people mistakenly believe that they can get vitamin A from eating plants, especially carrots. Sorry, Bugs Bunny, but that’s not how it works. Plants don’t contain vitamin A; they contain beta-carotene, and the body is not very good at converting beta-carotene into vitamin A. The result is that some people develop vitamin A deficiency even while consuming far more beta-carotene than they require. Unless you eat a lot of liver or oysters, taking real, preformed vitamin A is a good idea, whether you are fasting or not. It can improve your immunity and even your sleep. I prefer 10,000 IU per day. (p. 186)
