Big effect
Vitamin C plus E slashed a key marker of oxidative damage by 1 µg/L in a meta-analysis — but the effect came from the pair, not C alone.
This is among the first meta-analyses to examine the combined effect of vitamins C and E on lipid peroxidation, so the finding is promising but still early — replication in larger, more diverse populations will be needed before we can say the combo reliably delivers this drop.
Lipid peroxidation is a process where free radicals damage cell membranes, and higher levels are linked to chronic disease. In a pooled analysis of 17 trials with 965 participants, taking 250–1000 mg of vitamin C together with vitamin E reduced this damage by about 1 µg/L on average. However, the results apply to the combination, not vitamin C by itself, and the evidence base is still thin.
Where this fits in the evidence
This is among the first studies we've indexed on Vitamin C for Reduced Lipid Peroxidation — treat it as an early signal until more research accumulates.
