The Claim
Acute supplementation with 1000 mg of vitamin C and 235 mg of vitamin E before endurance exercise has no significant effect on exercise-induced muscle damage as measured by creatine kinase levels in endurance-trained male runners aged 39–58 years.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Taking 1000 mg of vitamin C and 235 mg of vitamin E before a long run does not lower the level of creatine kinase in the blood, which is a marker of muscle damage, in male runners aged 39–58 who regularly train for endurance events.
See the scientific wording
Acute supplementation with 1000 mg of vitamin C and 235 mg of vitamin E before endurance exercise does not significantly reduce exercise-induced muscle damage, as measured by creatine kinase levels, in endurance-trained male runners aged 39–58 years, suggesting that this antioxidant regimen does not protect against muscle cell disruption following prolonged running.
Taking vitamin C and vitamin E before running does not stop the physical tearing of muscle cell membranes that happens when muscles are stretched and contracted hard for a long time, so muscle proteins leak into the blood at the same rate whether or not the vitamins are taken.
What the research says
1 studyThe study gave runners vitamins C and E before a long run and found they didn’t help reduce muscle damage compared to those who took a fake pill. So, taking these vitamins before running doesn’t protect your muscles.
