Vitamin C post training of little benefit?

Realize this is on endurance athletes, but still relevant if you compare for instance to a glycogen depeltion workout.

Abstract
The aim of the present study was to investigate the effect of vitamin C with or without carbohydrate consumed acutely in beverages before and during prolonged cycling on immunoendocrine responses. In a single blind, randomized manner six healthy, moderately trained males exercised for 2.5 h at 60% VO2max and consumed either placebo (PLA), carbohydrate (CHO, 6% w/v), vitamin C (VC, 0.15% w/v) or CHO+VC beverages before and during the bouts; trials were separated by 1 wk. CHO and CHO+VC significantly blunted the post-exercise increase in plasma concentrations of cortisol, ACTH, total leukocyte, and neutrophil counts and limited the decrease in plasma glucose concentration and bacteria-stimulated neutrophil degranulation. VC increased plasma antioxidant capacity (PAC) during exercise (P < 0.05) but had no effect on any of the immunoendocrine responses (P > 0.05). CHO+VC increased PAC compared to CHO but had no greater effects, above those observed with CHO alone, on any of the immunoendocrine responses. In conclusion, acute supplementation with a high dose of VC has little or no effect on the hormonal, interleukin-6, or immune response to prolonged exercise and combined ingestion of VC with CHO provides no additional effects compared with CHO alone.

The primary impetus for taking vitamin C after a workout is to combat oxidative stress caused by strength training, as mentioned in the abstract. Vitamin C has plenty of general benefits, but I don't think there were any solid grounds for expecting other effects specific to the PWO timeframe.

i remember reading some studies that showed hi dose oral Vit C blunted the release of cortisol in response to excercize

Yep, my conclusion also. Kind of disheartening, I have always been an advocate of Vit. C pwo. Oh well, we learn. I was hoping supercompensation of antioxidants as well at this time.
