Beyond Oranges: Fruits Packed with Vitamin C

When it comes to boosting your immune system, vitamin C is a key player. Even as oranges are often the first fruit that comes to mind, many other fruits contain significantly higher levels of this essential nutrient. Let’s explore some of the top vitamin C-rich fruits to incorporate into your diet.

Why is Vitamin C Important?

Vitamin C, likewise known as ascorbic acid, is crucial for a variety of bodily functions. The Mayo Clinic explains that it’s needed to form blood vessels, cartilage, muscle, and collagen in bones, and also helps the body absorb iron. It’s a powerful antioxidant that protects cells from damage caused by free radicals, potentially reducing the risk of chronic diseases.
