👉 An antioxidant is a substance that helps to protect cells and tissues from damage by scavenging free radicals, which are unstable molecules that can cause damage. These antioxidants include vitamins C, E, and K, as well as various compounds like polyphenols, flavonoids, and carotenoids. Antioxidants help to prevent oxidative stress in the body, which is a process where the body's cells become damaged by free radicals.
