|The anti-long-term health, but pro short term fat loss effects of vitamin C + E|
A couple of days ago, I wanted to cite the paper in a different context and took a closer look at the actual results (yeah, even I sometimes only read the abstract) and as it turns out,...
...the scientists left out some information, you may be interested in, ...
...even though it may not be relevant from a statistical perspective. How I know things about your interests?Based on the visitor statistics of the SuppVersity. I just have to take a brief look at them to know that the vast majority of you will be intrigued to hear that the "daily vitamin C and E supplementation" (1000mg vitamin C and 235mg vitamin E per day), although it may have "attenuated increases in markers of mitochondrial biogenesis following endurance training", led to an albeit non-significant, but highly conspicuous 60% increase in body fat reduction.

This does not mean that these effects on the body composition are "real", i.e. actually due to the provision of vitamin C + E. What it does mean, though is that the occurred, although there was no visible training effect on the mitochondrial capacity and thus in the absence of any visible / measurable training effects.
