What antioxidants scavenge or quench what radicals?

Antioxidants are compounds that neutralize free radicals, which are unstable molecules that can cause cellular damage. Key antioxidants include vitamin C, which scavenges reactive oxygen species (ROS) like superoxide and hydroxyl radicals; vitamin E, which primarily protects cell membranes from lipid peroxyl radicals; and glutathione, which detoxifies a variety of reactive nitrogen species (RNS) and peroxides. Together, these antioxidants help maintain cellular health by mitigating oxidative stress.
