Product Description Vitamin C, also called ascorbic acid, is a water-soluble vitamin. Vitamin C participates in a variety of reactions in the body, such as participating in redox processes, and plays an important role in biological oxidation and reduction and cellular respiration. Vitamin C can resist the damage of free radicals to cells and improve human immunity. Some fruits and vegetables contain a lot of vitamin C, such as lemons, kiwis, cherries, citrus fruits, guava, green or red peppers, mustard greens, spinach, strawberries, grapes and tomatoes. However, vitamin C is extremely unstable and is easily destroyed during storage, processing and cooking. In addition, vitamin C is easily oxidized and decomposed.
