Oxidative stress is caused by the presence of free radicals in the body produced as a result of metabolism.
-
Free radicals have an unpaired electron and therefore are chemically very active as they are always seeking an excess electron.
-
This makes them reduce the DNA, lipids, etc. in the body to obtain the electron.
-
Antioxidants, on the other hand, can prevent this by donating an electron without becoming unstable. Antioxidants are therefore a solution to oxidative stress.
-
Glutathione is an antioxidant that is produced by your body.
-
Glutathione supplements are also available.
-
Studies have shown that oxidative injury to neurons resulting from glutathione depletion can be remedied by the administration of both vitamin K1 and vitamin K2.
