What are antioxidants?

Antioxidants are compounds whose primary function is to protect our body from the molecules known as free radicals (among others) that cause oxidative stress. This oxidative damage is responsible for a major degenerative diseases of the circulatory system, cardiovascular disease, cataracts, premature ageing and cancer, all of which are now the main cause of death in our society.
Free radicals disrupt the smooth functioning of the cells of our body, attacking key structural components therefore, such as lipids and proteins in the cell membrane, and even DNA enzymes responsible for the operation and refurbishment cell.
