Immune system antioxidants role

Phosphorus, vitamin D, and calcium are all needed for bone health (Huth et al., 2006) and selenium has a role in the immune and antioxidant systems and in DNA synthesis and repair. Zinc is necessary for DNA repair, cell growth, gene expression, and is an essential part of some enzymes and metalloproteins. Magnesium has been implicated in the prevention of CVDs (Haug et al., 2007). For example, it is known that calcium, phosphorus, and magnesium may mediate beneficial effects on... 

As noted previously, Zn has an important role in numerous critical biochemical processes, including immunity. In addition to the positive effects of Zn supplementation, various antioxidant vitamins have been shown to stimulate the immune system. Thus, supplementation of elderly individuals with a combination of vitamins A, C, and E showed significant improvement in the following cell-mediated responses (P12) (a) increased total number of circulating T-cells (b) increased the number of helper (CD4+) T-cells (c) increased helper-to-cytotoxic cell ratio (CD4+ to CD8+) and (d) increased total number of lymphocytes in response to phytohemagglutinin. Others (M12), in a double-blind, placebo-controlled study of an elderly group supplemented with vitamin E, demonstrated (a) increased... 

Vitamin E Vitamin E (a-tocopherol) functions as an antioxidant that promotes normal formation of red blood cells and normal function of the nervous and immune systems. The main dietary sources of vitamin E are vegetable oils normally, it is possible, unless people consume a very low-fat diet, to obtain amounts of vitamin E intake from foods that are sufficient to prevent signs of deficiency. However, vitamin E is a commonly consumed supplement, likely because of its hypothesized role in decreasing risk of CVD, prostate cancer, and various other chronic diseases.
