The Claim
Acute vitamin C and E supplementation has no significant effect on post-exercise jump performance or muscle-tendon stiffness 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 vitamin C and E supplements right after running does not change how high a runner can jump or how stiff their muscles and tendons become after exercise.
See the scientific wording
Acute vitamin C and E supplementation does not significantly improve or impair post-exercise jump performance or muscle-tendon stiffness in endurance-trained male runners aged 39–58 years, indicating that this antioxidant regimen does not meaningfully alter neuromuscular recovery after prolonged running.
Taking vitamin C and E after running does not change how the muscles and tendons respond to force or how the nerves activate the muscles the next day, because the body's natural repair processes are not disrupted by these vitamins at the doses used.
What the research says
1 studyTaking vitamin C and E before a run didn't help or hurt how high the runners could jump or how stiff their legs felt the next day — both groups with and without vitamins performed the same.
