In an 11 week trial recently published in The Journal of Physiology, researchers at the Norwegian School of Sport Sciences in Oslo assessed the effect vitamin C and E have on exercise endurance. 54 participants received either 1,000 mg of vitamin C plus 235 mg of vitamin E or placebo and they exercised up to four times a week. Researchers found no difference in performance between the two groups. However, those who took vitamin C and E seemed to produce less of a specific mitochondrial marker in their muscle cells, which suggests of a decrease endurance. What are your thoughts about this study? What are your typical recommendations to patients looking to enhance their exercise endurance?
