Orange juice may be the go to drink for vitamin C, but new research shows that other fruit juices may contain just as much. Using a new, more accurate method of measuring vitamin C, scientists found that some brands of apple juice, and even grape and pineapple juice, contain levels of vitamin C that are as high  or higher than those in orange juice. If you are not an orange juice fan, or just want more variety, you can switch it up a little and still get your vitamin C.
