Polyphenols as potential metabolism mechanisms regulators in liver protection and liver cancer prevention
Cell proliferation (2023) · Systematic review
This review systematically illustrates that various polyphenols, including resveratrol, chlorogenic acid, caffeic acid, dihydromyricetin, quercetin, catechins, curcumin, etc., improve metabolic disorders through direct or indirect pathways to protect the liver and fight liver cancer.
Flavonoids-mediated SIRT1 signaling activation in hepatic disorders
Life sciences (2020) · Systematic review
Additionally, molecular modeling simulations were applied to explore the potential binding mode of these flavonoids to SIRT1.
Metabolic mechanisms of Dihydromyricetin and strategies for enhancing its bioavailability: A recent review
Food chemistry (2025) · Systematic review

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
Conversely, the risk of term PROM was increased when supplementation included vitamin C and vitamin E (average RR 1.73, 95% CI 1.34 to 2.23; 3060 participants; two studies; I² = 0%).
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.
Evidence primarily from systematic reviews examining polyphenol hepatoprotective mechanisms rather than direct DHM clinical trials. Bioavailability limitations may reduce actual effectiveness. Conservative estimates given lack of specific dose-response studies.
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.
Both DHM and Vitamin C are closely matched — the best choice depends on your specific health goals.
For reduce inflammation, DHM has a higher relevance score (75 vs 65).
