Vitamin C & E Supplements Hinders Muscle Endurance?
(Ivanhoe Newswire) - Vitamins supplements are widely used, but a new study by the Norwegian School of Sport Sciences shows that taking some supplements, particularly Vitamins C and E, may slow down the improvement of muscular endurance.
In the 11-week study, 54 young men and women were randomly given either 1,000mg of Vitamin C and 235 mg of Vitamin E, or a placebo. After completing an endurance training program, the results showed that the production of new muscle only increased in the group without supplements.
The study leader, Dr. Goran Paulsen, said future studies are needed to determine the underlying mechanisms of these results, but he assumes the vitamins interfered with cellular signaling and blunted the expression of certain genes.
