Taking 1000 mg of vitamin C and 235 mg of vitamin E daily keeps blood levels of these antioxidants high during and after workouts, ensuring they are present when muscles are most stressed and repairing.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
A meta-analysis would determine the typical plasma concentration profile of vitamin C and E after various dosing regimens during exercise recovery across populations.
A systematic review and meta-analysis of all pharmacokinetic studies measuring plasma vitamin C and E levels after oral doses of 500–2000 mg vitamin C and 100–500 mg vitamin E in healthy adults undergoing resistance training, with standardized sampling times (pre, post, 2h, 4h, 6h post-exercise).
An RCT could confirm that this specific dosing regimen reliably achieves target plasma levels in diverse populations.
A double-blind RCT with 60 healthy adults (30 young, 30 elderly) randomized to 1000 mg vitamin C + 235 mg vitamin E or placebo, with serial plasma sampling (pre, 1h, 3h, 6h, 24h post-supplement) during a resistance training session to quantify pharmacokinetic profiles.
A cohort study could track how plasma vitamin levels change over time with habitual supplementation during training.
A 6-month prospective cohort following 100 resistance-trained adults who self-report daily vitamin C/E supplementation, measuring plasma levels monthly during training sessions and correlating with training volume and diet.
A cross-sectional study could estimate average plasma levels in supplement users versus non-users during training.
A cross-sectional study measuring plasma vitamin C and E levels in 300 resistance-trained adults who either take or do not take daily supplements, sampled within 2 hours of their last training session.
A case report could document extreme or unusual plasma responses to this dosing regimen in an individual.
A case report describing plasma vitamin C and E concentrations over 24 hours in a single individual taking 1000 mg vitamin C and 235 mg vitamin E before and after resistance training, with detailed dietary and metabolic logs.
