What is Vitamin C
Vitamin C, also known as ascorbic acid, is a water-soluble vitamin that is widely found in a variety of fruits and vegetables, such as citrus fruits, strawberries, kiwifruit, tomatoes, green peppers and green leafy vegetables. It cannot be synthesized in the human body and must be obtained through daily diet or nutritional supplements. Vitamin C has many important physiological functions. First of all, it is a powerful antioxidant, which can help eliminate free radicals in the body, slow down cell oxidative damage, delay the aging process, and enhance the body's immunity. Secondly, vitamin C is involved in the synthesis of collagen, which is essential for the health of skin, blood vessels, bones and connective tissues, helping to heal wounds and maintain the integrity of tissue structure. In addition, vitamin C can also promote the absorption of iron, especially help to improve the bioavailability of iron in plant foods and prevent iron deficiency anemia. It also participates in many metabolic reactions in the body, supports the normal function of the nervous system, and helps reduce fatigue and improve mental state. Long-term lack of vitamin C may lead to scurvy, manifested as bleeding gums, skin ecchymosis, joint pain, decreased immunity and other symptoms. Therefore, maintaining adequate vitamin C intake is important for maintaining overall health. According to nutrition recommendations, adults should consume the right amount of vitamin C every day, and a balanced diet can usually meet the body's needs.
