Ácido ascórbico, commonly known as vitamin C, is a water-soluble vitamin essential for various bodily functions. It plays a crucial role in the synthesis of collagen, which is vital for skin, cartilage, and bone health. Additionally, it acts as an antioxidant, helping to protect cells from damage caused by free radicals. Humans cannot produce ácido ascórbico naturally, so it must be obtained through diet. Rich sources include fruits like oranges, kiwis, and strawberries, as well as vegetables such as bell peppers and broccoli. Adequate intake is important for maintaining a healthy immune system and overall well-being.
