The Exogenous Antioxidants

One theory that was initially questioned was the proposal of Dr. Denhan Harman (1956) of the University of Nebraska. He was the first researcher to propose Free radicals (FR) as an important cause of cellular aging. Today this theory enjoys wide approval. FR are “disequili‐ brated” molecules that travel through our organism attempting to capture an electron of the stable molecules to obtain its electrochemical stability [1,2].
