Phytotherapy research : PTR (2025) · Meta analysis · n=1337
For HbA1c, silymarin was more effective than resveratrol (MD -2.08, 95%Cl -3.50 to -0.72) (P < 0.05).
Effects of different natural products in patients with non-alcoholic fatty liver disease-A network meta-analysis of randomized controlled trials
Phytotherapy research : PTR (2024) · Meta analysis · n=2509
The results of the network meta-analysis showed that artichoke leaf extract confers a relative advantage in reducing the aspartate aminotransferase (AST) levels (SUCRA: 99.1%), alanine aminotransferase (ALT) levels (SUCRA: 88.2%) and low-density lipoprotein cholesterol (LDL-C) levels (SUCRA: 88.9%).

The Cochrane database of systematic reviews (2017) · Meta analysis · n=9955
A complete case analysis (i.e. participants who completed the study) among trials investigating CDAD (31 trials, 8672 participants) suggests that probiotics reduce the risk of CDAD by 60%.
Based on multiple meta-analyses showing significant ALT/AST reduction. Effect size modest (SMD -0.67 to -0.9). Effectiveness assumes standardized 80% silymarin extract. Lower bioavailability forms may require higher doses.
Based on meta-analyses showing benefits for IBS and digestive symptoms. Effect sizes varied considerably between studies with low to very low certainty of evidence. Initial GI symptoms common when starting but typically resolve within 1-2 weeks.
