The Claim
Acute supplementation with vitamin C and E has no significant effect on blood lactate response during 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 a long run does not change the level of lactate in the blood during the run in trained male runners aged 39–58.
See the scientific wording
Acute vitamin C and E supplementation does not significantly affect blood lactate response to endurance exercise in trained male runners aged 39–58 years, indicating that this antioxidant regimen does not alter metabolic stress or anaerobic threshold during prolonged running.
Taking vitamin C and E before running does not change how much lactic acid builds up in the blood because the muscles still produce lactic acid at the same rate and the body still removes it at the same speed, no matter what antioxidants are present.
What the research says
1 studyThe study gave some runners vitamin C and E before a run and others a placebo, then checked their blood for lactic acid. Both groups had the same amount of lactic acid after running, so the vitamins didn’t change anything.
