An object of the present invention is to provide an antioxidant composition that is effective in the living body against active oxygen species produced in the body. The present invention provides an antioxidant composition having the effect of suppressing three active oxygen species, i.e. hypochlorite radicals, hydroxyl radicals, and peroxynitrite radicals, with respect to active oxygen species produced in the body, the antioxidant composition comprising a mixture in which at least 20 mg of vitamin C (L-ascorbic acid or sodium L-ascorbate) as an agent to scavenge peroxynitrite active oxygen, and at least 2 mg of caffeic acid analogue compound(s), at least 10 mg of polyphenyol compound(s) or at least 1.5 mg of carotenoid compound(s) as an agent to scavenge hydroxyl radical active oxygen are combined with 100 mg of histidine-containing dipeptide, or sulfur-containing amino acids or analogues thereof obtained from animal extract as an agent for scavenging hypochlorite active oxygen.
