The Claim
Acute supplementation with vitamin C and E has no significant effect on delayed onset muscle soreness or perceived exertion during or after endurance exercise in 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 vitamin C and E supplements shortly before or after long-distance running does not reduce muscle soreness or the feeling of effort in trained male runners aged 39–58.
See the scientific wording
Acute vitamin C and E supplementation does not significantly alter delayed onset muscle soreness or perceived exertion during or after endurance exercise in trained male runners aged 39–58 years, indicating that these antioxidants do not meaningfully reduce subjective muscle discomfort following prolonged running.
Taking vitamin C and E before running does not change how much muscle tissue is damaged or how the brain senses effort and soreness afterward, because the body's natural repair signals and nerve responses to fatigue are not affected by these supplements.
What the research says
1 studyThe study gave some runners vitamin C and E before a long run and others a fake pill — and both groups felt just as sore and tired afterward. So, the vitamins didn’t help reduce soreness or effort.
