Vitamin C supplementation for prevention and treatment of pneumonia
The Cochrane database of systematic reviews (2020) · Meta analysis · n=2774
We are uncertain of the effect of vitamin C supplementation on mortality due to pneumonia (RR 0.21, 95% CI 0.03 to 1.66; 1 study, 57 participants; very low-quality evidence).
Vitamin C supplementation in pregnancy
The Cochrane database of systematic reviews (2015) · Meta analysis · n=20038

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 3 RCTs in dental surgery patients. Effects were modest and one study showed dexamethasone was superior. Requires enteric-coated formulation for bioavailability.
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.
AI-estimated from published studies. Interpret as directional guidance.
Vitamin C has a higher evidence score (8/10 vs 4/10) and wins in 3 of 3 categories.
For speed up recovery, Vitamin C has a higher relevance score (75 vs 65).
No known interactions between Serrapeptase and Vitamin C have been documented in our database. However, always consult a healthcare provider before combining supplements.
