Vitamin C is a water-soluble organic substance that cannot be synthesized by the body; therefore, it must be obtained from an individual's daily diet. Also known as ascorbic acid, it is involved in wound healing and collagen production by preventing iron-dependent oxidation of lysyl and prolyl hydroxylase. In human and animal studies on vitamin C defi ciency, ascorbate supplementation increased collagen synthesis and decreased polymorphonuclear neutrophil (PMN) chemotaxis [ 4 , 5 , 9 ]. High vitamin C levels are accumulated in granulocytes, mononuclear leucocytes, and platelets [ 28 ], and neutrophil polymorphonuclear leucocytes and macrophages contain an intracellular ascorbate concentration that is 10-40 times higher than that in the plasma [ 58 ]. Chapple and Matthews [ 19 ] summarized the following functions of vitamin C: (1) scavenging water-soluble peroxyl radicals; (2) scavenging superoxide and perhydroxyl radicals; (3) preventing damage mediated by hydroxyl radicals on uric acid; (4) scavenging hypochlorous acid; (5) decreasing heme breakdown and subsequent Fe 2+ release, thereby preventing Fenton reactions; (6) scavenging single oxygen and hydroxyl radicals; (7) re-forming α-tocopherol from its radical; (8) protecting against reactive oxygen species (ROS) released from cigarette smoke; (9) reducing C-reactive protein-mediated expression of monocyte adhesion molecules; (10) decreasing pro-infl ammatory gene expression through effects on the nuclear factor-κB transcription factor.Vitamin E, which comprises related compounds named tocopherols or tocotrienols, is a fat-soluble vitamin with primary function of antioxidation. It is essential for maintaining cell membrane integrity against lipid peroxidation by peroxyl
