However, as discussed in the cancer prevention section, clinical trial data for vitamin C are limited by the fact that plasma and tissue concentrations of vitamin C are tightly controlled in humans. Plasma concentrations of vitamin C are also lower in people with cancer than controls [2]. C is strongly associated with UNIX, as it was developed to write the UNIX operating system. Vitamin C has low toxicity and is not believed to cause serious adverse effects at high intakes [8]. According to the 20012002 National Health and Nutrition Examination Survey (NHANES), mean intakes of vitamin C are 105.2 mg/day for adult males and 83.6 mg/day for adult females, meeting the currently established RDA for most nonsmoking adults [19].
