In a normal, healthy individual eating a diet rich in vitamin C, we might expect adequate levels of vitamin C for normal cell functions. Any condition that would decrease these levels, such as smoking or chronic diseases, would therefore result in a decline in cell function. Of particular interest to our laboratory is the observation that vitamin C levels appear to decline in the elderly. This has been observed not only in human plasma, but also in plasma and tissues in rats, our model system. Why do vitamin C levels decline with age? The most straightforward answer is that vitamin C uptake declines with age. In other words, our bodies don't have the same capacity to absorb vitamin C, so vitamin C levels in the plasma and tissues become lower. This has been supported by a recent meta-analysis, which showed that the elderly had much lower plasma vitamin C levels than younger adults following a given dose of vitamin C. This suggests that vitamin C absorption in the gut declines with age. Vitamin C absorption is

Been treated for skin cancer and given yeast-derived organic selenium (200 µg selenium per day) or a placebo for several years, selenium had no significant effect on skin cancer reoccurrence, but showed a remarkably large effect on the occurrence of lung cancer (46% reduction), colon-rectum cancer (58% reduction), and prostate cancer (63% reduction). Clinical studies to further explore these findings are under way.

Studies in animals indicate that DHA is required for the normal development and function of the retina.

Zinc is a nutrient your body needs for many essential functions such as growth and development, maintenance of the body?s immune system, wound healing and appetite control. Recent research also suggests that zinc positively impacts cognitive function and behavior not only in early development, but throughout life.

The term "vitamine" was first proposed in 1912 by the Polish chemist Casimir Funk, in his landmark paper on vitamin theory, which synthesized existing research and paved the way for developments in the field..
