Vitamin C, also known as ascorbic acid, is a water-soluble vitamin essential for various bodily functions. It plays a crucial role in the growth and repair of tissues, helps in the production of collagen, and acts as an antioxidant, protecting cells from damage caused by free radicals. This vitamin is commonly found in fruits and vegetables, particularly in citrus fruits like oranges and lemons, as well as in kiwis, strawberries, and bell peppers. A deficiency in vitamin C can lead to scurvy, characterized by symptoms such as fatigue, gum disease, and skin issues.
