The fruit known for having a lot of vitamin C is the orange. This citrus fruit is not only refreshing and delicious but also packed with nutrients, primarily vitamin C, which supports the immune system and promotes healthy skin. A medium-sized orange typically contains about 70 milligrams of vitamin C, exceeding the daily recommended intake for adults. In addition to vitamin C, oranges are a good source of fiber, folate, and antioxidants, making them a nutritious addition to any diet. Their sweet and tangy flavor also makes them a popular choice for juices and snacks.
