I would like to personally thank Terence from Camp Sherman Oregon for sending in the following question. He asked is carrot juice a rich source of potassium? The answer to the question is yes, raw homemade carrot juice is a rich source of potassium. One solitary cup of raw homemade carrot juice contains roughly twenty percent of the daily recommended value of potassium. If you are interested in increasing the amount of potassium per cup, then simply juice your carrots along with one or two bananas. It should be noted that the amount of potassium stated in this answer only pertains to raw homemade carrot juice. Bottled or pasteurized carrot juice usually contains substantially less vitamins and minerals, unless of course it is vitamin fortified. We greatly appreciate Terence taking the time to submit this question to us. If you have any other carrot juice related questions, please drop us a note.
