Antioxidants are molecules that can help the body fight off harmful free radicals, which have been linked to health conditions like diabetes and cancer. They are found in many plant-based foods and are essential for the body to maintain a balance between free radicals and antioxidants. Some examples of antioxidants include vitamin C, vitamin E, beta-carotene, and flavonoids. They work by neutralizing free radicals, which can cause cell damage and lead to oxidative stress. Antioxidants are naturally occurring in many fruits and vegetables and are also available as dietary supplements
. Some substances that act as antioxidants in one situation may be pro- oxidants in another, and each antioxidant has unique chemical behaviors and biological properties
. High-dose supplements of antioxidants may be linked to health risks in some cases, so it's important to consume them in appropriate amounts
