Antioxidants are essential molecules that protect our cells from damage caused by free radicals. Free radicals are unstable molecules that can damage DNA, proteins, and lipids, leading to a variety of health problems, including cancer, heart disease, and Alzheimer's disease. Antioxidants neutralize free radicals by donating an electron, which stabilizes the free radical and prevents it from causing damage.

There are two main types of antioxidants: endogenous antioxidants, which are produced by the body, and exogenous antioxidants, which are found in food and supplements. Endogenous antioxidants include glutathione, superoxide dismutase, and catalase. Exogenous antioxidants include vitamin C, vitamin E, beta-carotene, and selenium.
