Our body needs five major types of nutrients to maintain metabolism, including sugars, proteins, fats, vitamins and minerals. People who are starved for nutrients can adopt a method called “intravenous nutrition”, which uses nutritional preparation to replenish multiple nutrients in a short time through the peripheral intravenous nutrient drip. For intravenous nutrition, the types and concentration of the contents can be adjusted according to the individual’s physical condition. The contents of the injections include high units of vitamin C, vitamin B complex, lipoic ac, ginkgo biloba, zinc sulphate, glutathione, glutamine and other ingredients. By providing nutrients and antioxidant supplementation, it facilitates tissue circulation and increases oxygen content, accelerates metabolism and provides protection against free radicals.
