• Americans With Highest Blood Levels Of Vitamins C and E Have Lowest Mortality Rate

    Posted August 1, 2013: by Bill Sardi

    Researchers at Columbia University have published a definitive study showing Americans with the highest blood concentrations of vitamins C and E, particularly dietary supplement users, have the lowest over-all mortality rates and death rates from cancer.

    The study involved 16,008 adults in the Third National & Nutrition Examination Survey.  Blood levels of vitamin C were 48% higher and vitamin E 30% higher among supplement users.  The group with the highest blood concentration of vitamin C were 45% less likely to die of any cause; vitamin E 29% lower death risk compared to adults with the lowest blood concentration.  The highest blood concentration of vitamin C also resulted in a relative 60% reduced risk for cancer-related deaths.  The study was published in the July edition of Cancer Epidemiology, Biomarkers & Prevention (July 2013) and utilized blood concentration rather than imprecise surveys that ask adults what vitamins they consume in their diet and supplements.  It is assumed the vast majority of those adults exhibiting the highest blood concentration of vitamins were taking dietary supplements.  ©2013 Bill Sardi, Knowledge of Health Inc.
