Carrots(07 of12)
Open Image ModalThe humble carrot is popular for a reason other than its great taste: it's full of beta-carotene, which our bodies turn into vitamin A. They're also a good juice base because their natural sweetness can help to mask stronger-tasting ingredients like kale or wheatgrass. (credit:Shutterstock)
Wheatgrass(08 of12)

Lemon(09 of12)
