Vitamin C for Immune Function

Greg Potter

There have been remarkably competent and influential advocates of the positive effects of consuming high doses of vitamin C. Of these, Linus Pauling stands out, not only because he won the Nobel Prize but also because he was so adamant that vitamin C can treat many health problems.
