Carotenoids

Consume collard juice as a source of carotenoids yellow, orange and red pigment compounds including beta carotene, lutein and zeaxanthin. Your body breaks down beta carotene into vitamin A, then uses it to support red blood cell growth, promote cell development and nourish your immune system. Drinking just 2 ounces of collard juice provides all the vitamin A you need in a day, according to the Linus Pauling Institute. Collards also provide 2,734 micrograms of lutein and zeaxanthin. These compounds promote healthy vision, and might protect you from eye diseases such as age related macular degeneration.
