A recent article in the NY Times discusses a new study (Oct. 2011) confirming the harmful effects of vitamin and mineral supplementation. Iron supplementation had the most harmful effects on mortality
A January 2009 editorial in The Journal of the National Cancer Institute noted that most studies of vitamins had shown no cancer benefits, but some had shown unexpected harms. Two studies of beta carotene found higher lung cancer rates, and another study suggested a higher risk of precancerous polyps among users of folic acid compared with those in a placebo group.
In 2007, The Journal of the American Medical Association reviewed mortality rates in randomized trials of antioxidant supplements. In 47 trials involving 181,000 participants, the rate of dying was 5 percent higher among the antioxidant users. The main culprits were vitamin A, beta carotene and vitamin E; vitamin C and selenium seemed to have no meaningful effect.
Ascorbic acid supplementation does not attenuate post-exercise muscle soreness following muscle-damaging exercise but may delay the recovery process.
Oral administration of vitamin C decreases muscle mitochondrial biogenesis and hampers training-induced adaptations in endurance performance
Antioxidants prevent health-promoting effects of physical exercise in humans: “Exercise increased parameters of insulin sensitivity (GIR and plasma adiponectin) only in the absence of antioxidants in both previously untrained (P < 0.001) and pretrained (P < 0.001) individuals.
