In brief, antioxidants are substances that protect the body's cells against free radicals released by oxidation processes in the body.

The aggressive free radicals attack the cells and cause premature ageing, arteriosclerosis, a weakened immune system and cancer.

 

The most important antioxidants are flavonoids, vitamins A, C and E, as well as the trace elements selenium, zinc, manganese, iron and copper.

 

Tea leaves, green leafy vegetables and the outer layers of plants contain antioxidants.
