Free Radicals Definition

Free radicals are unstable molecules that damage any tissue in the body they come in contact with.

This causes a cascade of tissue damage and inflammation. Inflammation itself generates even more free radicals.

Anti-oxidants such as glutathione, vitamin C, D, E and K, as well as many others, stabilize the free radicals and therefore stop the tissue damage, the cascade of damage and the resulting inflammation.

Congratulations! We are so happy to hear that!
