A study published in the Journal of the American Medical Association (JAMA) in November cast doubt on whether long-term supplementation with vitamins E or C could decrease the risk of major cardiovascular events among men. However, a US scientist representing the Natural Products Association points to flaws in the study’s design that could have skewed results. "On the second page of the study, it references nine pooled studies that when using 700 mg per day of vitamin C showed a 25% reduction in the occurrence of cardiovascular disease (CVD); yet this study only used 500 mg per day. Why wasn’t the 700 mg amount used when that has been correlated with a reduction in occurrence in prior studies?" questions Daniel Fabricant, PhD. Fabricant also points out that intake of the antioxidant nutrients from the diet was not controlled and "would most certainly confound the study."
