The fruit known for its high levels of vitamin C is the orange. Oranges are a type of citrus fruit that are not only refreshing and sweet but also packed with nutrients, particularly vitamin C, which is essential for immune function, skin health, and the synthesis of collagen. Beyond vitamin C, oranges also provide dietary fiber, antioxidants, and several other vitamins and minerals. This makes them a popular choice for those looking to enhance their nutrition while enjoying a tasty snack or incorporating them into meals and beverages.
