Vitamin C, also known as ascorbic acid, is renowned for supporting the immune system. It plays a crucial role in various bodily functions, including the stimulation of white blood cell production, which helps the body fight off infections and diseases. Additionally, Vitamin C acts as an antioxidant, protecting cells from damage by free radicals and promoting healthy skin, cartilage, and blood vessels. As a water-soluble vitamin, it must be consumed regularly through diet, with rich sources including citrus fruits, berries, bell peppers, and leafy greens. Adequate intake is essential for overall health and well-being.
