Enhanced Vitamin C Delivery: A Systematic Literature Review Assessing the Efficacy and Safety of Alternative Supplement Forms in Healthy Adults
Nutrients (2025) · Systematic review
Most studies (77%) had a low risk of bias.
Based on meta-analyses showing significant reductions in IL-6, TNF-α, and CRP. Effect sizes were modest with WMD of -2.48 for IL-6 and -0.86 for TNF-α. Conservative effectiveness reflects variable study quality and heterogeneity between trials.
Based on 3 meta-analyses of sepsis patients. One study showed RR 0.60 for mortality reduction, but another showed increased risk (RR 1.21). Evidence quality rated as low to very low. Effect limited to intravenous administration in critically ill patients.
