An antioxidant, or also called a radical scavenger, can interrupt the chain reactions of free radicals and in this way prevent cell damage and thus also diseases. Free radicals are oxygen-containing molecules that are dangerously unstable because they are missing an electron in their chemical structure. In their “search” for the missing electron, free radicals act extremely aggressively. The next best intact molecule in the body is simply “robbed” of the required electron. This “electron theft” is called oxidation. If the oxidations in the body’s cells exceed a tolerable level, so-called oxidative stress occurs. The cells are damaged, which can lead to various diseases. This is where antioxidants come in, because they give up one of their electrons “voluntarily” and thus protect the cells. The most antioxidant substances include vitamins, minerals, trace elements, enzymes and secondary plant substances.
