People who are exposed to tobacco products and smoke require substantially larger doses of the antioxidant vitamin C since it protects delicate blood components from harm.
Antioxidants are chemicals that inhibit oxidation, a chemical reaction that can lead to the generation of free radicals. Examples of antioxidants include the carotenoids beta-carotene, lycopene, lutein, and zeaxanthin as well as the vitamins C and E, selenium, and these carotenoids. Polymerization and other chain reactions may result from this. These defences are referred to as "antioxidants," and they work by readily distributing free radicals electrons without themselves converting into electron-scavenging compounds. This fact sheet provides background information on antioxidants, a summary of the scientific research on antioxidants and health, and recommendations for more reading. Inorganic compounds called antioxidants reduce the harm that free radicals inflict to the body. Free radicals are extremely reactive chemicals that can either be formed by the body naturally during regular metabolic processes or consumed from the outside by exposure to toxins and other contaminants, for example.
