The Claim
Oral supplementation with vitamins C and E during 10 weeks of resistance training in healthy young adults has no significant effect on increases in whole muscle cross-sectional area, myofiber size, or one-repetition maximum strength.
What the research says
Not yet evaluated
We are still looking at what the research says.
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 while doing 10 weeks of resistance training does not change how much muscle size or strength increases in healthy young adults.
See the scientific wording
Oral supplementation with vitamins C and E during 10 weeks of resistance training in healthy young adults does not significantly alter increases in whole muscle cross-sectional area, myofiber size, or one-repetition maximum strength, suggesting antioxidant intake does not impair overall muscle hypertrophy or maximal strength gains from resistance exercise.
Taking vitamin C and E supplements during strength training reduces the natural rise in reactive oxygen species after exercise. This reduction stops some of the chemical signals that normally fine-tune muscle protein breakdown and growth pathways, but it does not stop the overall buildup of muscle size or maximum strength because other pathways take over to maintain protein balance.
What the research says
1 studyTaking vitamin C and E pills while doing strength training didn’t stop people from getting bigger muscles or stronger, even though their muscles didn’t feel as strong for their size. So the supplements didn’t ruin their gains.
