Antioxidants<\/strong> \u2014 are molecules that protect the cells of our body from damage caused by free radicals. These radicals are formed as a result of normal metabolic processes or under the influence of harmful factors, such as ultraviolet light, pollution, smoking, stress, and poor diet. The level of antioxidants in the blood reflects the body's ability to resist oxidative stress, which is associated with the development of many chronic diseases \u2014 from cardiovascular to cancer.<\/p>\n

What does an antioxidant level test show?<\/strong><\/h2>\n

This test measures the total antioxidant capacity (TAC) in serum or plasma. It can be performed using different methods (e.g. FRAP, ORAC or TEAC), but the result is an estimate of the body's overall ability to neutralize free radicals. Levels of individual antioxidants, such as vitamins C, E, carotenoids, glutathione, selenium or enzymes such as superoxide dismutase, are often also assessed.<\/p>\n
