What are antioxidants and what do they do?

Antioxidants are small molecules that protect the cell from cellular damage caused by free radicals.

Free radicals are atoms or groups of atoms that have an unpaired electron, and can be formed within the body by interactions with certain molecules and also environmental factors. Free radicals are highly reactive and can damage sensitive parts of your cells such as your DNA and your cell membrane. Free radicals can also self-propagate in chain reactions meaning that they can interact with other small atoms to form even more free radicals and so on.

Of course your body has a defence against these damaging agents, and that is where antioxidants come in. They are the good guys, which ‘scavenge’ free radicals by terminating their chain reaction and stop them damaging cellular components in their tracks.



By reducing damaging agents you facilitate the cell repair and regeneration required for good health. You can efficiently raise your antioxidant level by limiting the amount of heavily processed foods and eating a more diet rich in antioxidants or juicing, but this can be expensive and time consuming.
