11. Immunocal versus antioxidants. How is it different from taking vitamins C and E, for example? 

Vitamin C is a highly effective antioxidant working to lessen oxidative stress, neutralize pollutants and thus strengthen the immune system. In one trial, blood glutathione levels rose nearly 50% in healthy people after taking 500 mg of vitamin C per day for two weeks. Vitamin C raises glutathione by helping the body manufacture it. Vitamin E acts in a similar way as vitamin C - it recycles glutathione and depends on it itself for proper function and recycling as well. Vitamin E is essential as an antioxidant and provides protection for the cells against free radical damage. Its role is particularly important in protecting fats, cell membranes, DNA and enzymes against damage. This vitamin is crucial for the maintenance of a healthy immune system as it protects the thymus gland and circulating white blood cells.

Although vitamins C and E play a role in raising glutathione levels, they act as co-factors of glutathione production, not as the main source of it, and they depend on glutathione, the master antioxidant, for their own proper functioning.

Without the three precursors of Glutathione production - amino-acids glutamate, glycine and cysteine - cells cannot make glutathione, no matter how much vitamin C and E is available. Out of these three amino-acids cysteine is the most crucial because it is rare in foods in the form that can enter cells. Immunocal delivers this crucial precursor cysteine into the cell in the form ready for glutathione production. Immunocal is clinically proven to raise AND maintain optimal glutathione levels in blood serum and tissue.
