Camille sent us the following question. How much beta-carotene does raw carrot juice contain? Raw carrot juice contains 1000% of the daily recommended value of vitamin A, which is in the form of beta-carotene. This organic substance is a red or orange colored pigment found not only within carrots, but also in a whole host of other fruits and vegetables. Plant carotenoids such as beta-carotene are the main source of vitamin A consumed as food. Carrot juice is by far the richest source of beta-carotene, however it is also abundant in yams, spinach, kale, sweet potatoes, mangoes, edible roots, and other leafy vegetables. It's important to limit the amount of beta-carotene in your diet, as over exposure to it has been linked with toxicity and cancer. I would like to thank Camille for sending us this question, and encourage our web guests to continue sending in other questions related to carrot juice.
