What Researchers Did
Researchers investigated if a 4-week daily supplementation of vitamins C and E could prevent oxidative stress induced by hyperbaric oxygen in 19 healthy men.
What They Found
Hyperbaric oxygen exposure decreased plasma vitamin C and antioxidative capacity, and increased lipid peroxides. While vitamin supplementation increased plasma vitamin C by 28% and vitamin E by 37%, it did not prevent the decrease in vitamin C and reduced glutathione, or the increase in lipid peroxides after hyperbaric oxygen exposure.
Canadian Relevance

Study Limitations
A limitation of this study is the small sample size of 19 healthy men, which may limit the generalizability of the findings.
