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.

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.
Vitamin C has a higher evidence score (8/10 vs 4/10) and wins in 2 of 3 categories.
For reduce inflammation, DHM has a higher relevance score (75 vs 65).
No known interactions between DHM and Vitamin C have been documented in our database. However, always consult a healthcare provider before combining supplements.
