Orange is often regarded as the major source of vitamin C, although other fruits and vegetables contain significant amounts as well. Citrus fruits such as grapefruits, lemons, and limes are well-known for their high vitamin C content. Bell peppers, kiwi, strawberries, and broccoli also contribute to daily vitamin C intake. This essential nutrient is vital for the growth and repair of tissues, as well as for the synthesis of collagen, aiding in wound healing. It also acts as an antioxidant, combating oxidative stress and boosting the immune system.
