The main source of vitamin C is found in fruits and vegetables, particularly citrus fruits like oranges, lemons, and grapefruits. Other excellent sources include strawberries, kiwi, bell peppers, broccoli, and Brussels sprouts. Vitamin C, also known as ascorbic acid, is essential for overall health as it helps in the growth and repair of tissues, supports the immune system, and acts as an antioxidant to combat free radicals in the body. Since the body cannot produce or store vitamin C, it is crucial to consume it regularly through a balanced diet, ensuring all health benefits are obtained.
