Vitamin C is a very common vitamin that is often supplemented when following surgical procedures because it promotes collagen synthesis and healing of surgical incisions. When the body is deficient in vitamin C, it tends to cause wounds that do not heal easily. In addition, vitamin C can promote the absorption of iron, so in iron deficiency anemia, it is necessary to supplement iron on the one hand and vitamin C on the other hand. vitamin C can play a role in protecting sulfhydryl groups, which can prevent lipid peroxidation of cell membranes and protect cell membranes. Vitamin C enables the reduction of methemoglobin in red blood cells to hemoglobin, which is the body’s role in transporting oxygen. Vitamin C protects the role of vitamin A from oxidation and the amount of vitamin C needed by adults is about 60mg per day.
