Vitamin C supplementation decreases training efficiency

There is considerable debate regarding the health effects of vitamin C supplementation. This brand new scientific study concludes that it decreases training efficiency because it prevents some key mitochondrial adaptations to exercise.

  

American Journal of Clinical Nutrition, Vol. 87,  No.1, 142-149, January 2008: Oral administration of Vitamin C descreases muscle mitochondrial biogenesis and hampers training-induced adaptations in endurance performance.

In my opinion, taking synthetic antioxidants regularly may not be wise. There's lots of hype about this powered by a multibillion-dollar supplement industry, so it's easy to get confused. I believe that research has shown quite clearly that although supplements may correct certain dietary deficiences, in the long run they simply cannot replace real food.
