L-ascorbic acid, commonly known as vitamin C, is a water-soluble vitamin that is essential for human health. It is a vital nutrient involved in the repair of tissue and the enzymatic production of certain neurotransmitters. L-ascorbic acid functions as an antioxidant, helping to protect cells from the damage caused by free radicals. It also plays a crucial role in the synthesis of collagen, which is important for the maintenance of skin, blood vessels, bones, and cartilage. Additionally, L-ascorbic acid enhances the absorption of iron from plant-based foods and supports the immune system. Humans cannot synthesize L-ascorbic acid endogenously, so it must be obtained through diet or supplements. Rich dietary sources of L-ascorbic acid include citrus fruits, strawberries, kiwi, bell peppers, broccoli, and spinach. A deficiency in vitamin C can lead to a condition known as scurvy, characterized by symptoms such as fatigue, swollen gums, joint pain, and poor wound healing.
