Vitamin C is also known as ascorbic acid. Ascorbic acid is an essential nutrient required for the proper functioning of the body. It is a water-soluble vitamin that acts as a powerful antioxidant, protecting cells from damage caused by free radicals. Ascorbic acid is found in a variety of fruits and vegetables, particularly citrus fruits like oranges and lemons. It plays a key role in the synthesis of collagen, a protein necessary for healthy skin, blood vessels, and connective tissues. It also aids in the absorption of iron and supports the immune system. It is important to consume an adequate amount of vitamin C through diet or supplementation as the body cannot produce it on its own.
