Rationale Metabolic dysfunction-associated steatotic liver disease (MASLD) is a major public health challenge, with approximately 32.4% of adults globally diagnosed with the condition and a steadily increasing prevalence.
We calculated risk ratio (RR) for dichotomous data and mean difference (MD) for continuous data, both with 95% confidence intervals (CI).
For rare events, we used the Peto odds ratio (OR) and 95% CI.

Borderline
For HbA1c, silymarin was more effective than resveratrol (MD -2.08, 95%Cl -3.50 to -0.72) (P < 0.05).
For body mass index (BMI), curcumin was more effective than resveratrol (MD -1.27, 95%Cl -2.43 to -0.03) (P < 0.05).
Curcumin, resveratrol, silymarin, and berberine can effectively improve cardio-metabolic risk factors in T2DM, and different herbal phytochemicals have different clinical advantages.

According to the findings of this meta-analysis silymarin administration showed a significant reduction in AST (SMD [95% CI]: - 0.670 [- 0.931, - 0.408], p-value = 0.000), and ALT (SMD [95% CI]: - 0.912 [- 1.177, - 0.646], p-value = 0.000) levels.
While it had no statistically significant effect on ALP level (SMD [95% CI]: - 0.236 [- 1.929, 1.458], p-value = 0.159).
The subgroup analysis was also showed significant decrease in AST and ALT levels for patients with BMI less than 30, while silymarin treatment had no significant effects on AST and ALT levels in patients with BMI ≥ 30.

Liu H et al. · Phytotherapy research : PTR (2024)
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%).
Naringenin conferred an advantage in reducing triglyceride (TG) levels (SUCRA: 97.3%), total cholesterol (TC) levels (SUCRA: 73.9%), and improving high-density lipoprotein cholesterol (HDL-C) levels (SUCRA: 74.9%).
High-density catechins significantly reduced body mass index (BMI) levels (SUCRA: 98.5%) compared with the placebo.

In addition, silymarin attenuated liver injury as indicated by the decreased levels of ALT (SMD[95%CI]=-12.39[-19.69, -5.08]) and AST (SMD[95% CI]=-10.97[-15.51, -6.43]).
The levels of fatty liver index (SMD[95%CI]=-6.64[-10.59, -2.69]) and fatty liver score (SMD[95%CI]=-0.51[-0.69, -0.33]) were also decreased.
Liver histology of the intervention group revealed significantly improved hepatic steatosis (OR[95%CI]=3.25[1.80, 5.87]).

In management RCTs, the efficacy parameter was usually 50 % decrease or normalisation of liver enzymes, or survival rate in DILI-related ALF patients.
Niu H et al. · Pharmacological research (2021)
In management RCTs, the efficacy parameter was usually 50 % decrease or normalisation of liver enzymes, or survival rate in DILI-related ALF patients.
In conclusion, heterogeneity among studies in DILI case qualification and methodologic quality was evident, and the RCTs performed demonstrated limited efficacy of specific interventions.
International research networks are needed to establish a framework on RCTs design and therapeutic endpoints.

Compared with other interventions, there were significant differences decreasing AST and ALT levels when SIL was used alone.
SIL has positive efficacy to reduce transaminases levels in NAFLD patients.

Berberis aristate and Silybum marianum resulted in no statistically significant change in ALT (weighted mean differences (WMD): -0.39 mg/dl; 95% CI: -1.67 to 0.89, P = 0.55), and AST (WMD: -0.44 mg/dl; 95% CI: -2.02 to 1.14, P = 0.58).
We did not find any significant reduction in liver enzymes following BBR-silymarin consumption in adults.
Further clinical trials with high quality according to the challenges mentioned seem to be helpful to use BBR-silymarin as a supplement for improving liver function.

Overall, silymarin significantly reduced the occurrence of anti-TB DILI at week 4 [RR: 0.33, 95% CI (0.15, 0.75)].
In addition, silymarin exerted protective effect on liver function in patients undergoing anti-TB drugs [SMD = - 0.15, 95% CI (-0.24, -0.07), P < 0.001 (ALT); SMD =-0.14, 95% CI (-0.23, -0.06), P = 0.001(AST); SMD =-0.12, 95% CI (-0.20, -0.03), P = 0.008 (ALP)].
Silymarin led to similar AEs in placebo groups [OR: 1.09, 95% CI (0.86, 1.39), P = 0.47].

The present findings suggest that the coadministration of berberine and silymarin is associated with an advantageous improvement in lipid and glucose profile, suggesting the possible use of this nutraceutical combination in order to promote the cardiometabolic health.
Fogacci F et al. · Phytotherapy research : PTR (2019)
Quantitative data synthesis was performed using a random-effects model.
We identified five eligible RCTs, with 497 subjects overall included.
Still, the inconsistent results across the included RCTs require further clinical research to establish optimal dosage and duration.
Ranneh Y et al. · Nutrients (2024)
Most studies on silymarin showed a reduction in liver enzymes and lipid profile; however, no changes were observed in inflammatory cytokine levels.
The dietary supplementation of hesperidin and naringenin or green tea extract caused improvements in liver enzyme, lipid profile, and inflammatory cytokine, while genistein supplementation did not modulate blood lipid profile.
In conclusion, dietary supplementation of polyphenols could potentially prevent and ameliorate NAFLD.
Additional high-quality RCTs with longer durations are required to determine the clinical efficacy of SIL supplementation on renal and oxidative stress markers.
Mohammadi S et al. · Phytotherapy research : PTR (2024)
In addition, there was a nonsignificant decrease in serum levels of gamma-glutamyl transferase, malondialdehyde (MDA), total bilirubin, albumin (Alb), total antioxidant capacity, and blood urea nitrogen.
Sub-group analyses revealed a considerable decline in MDA and Alb serum values among SIL-treated participants with liver disease in trials with a longer duration (≥12 weeks).
These findings suggest that SIL may ameliorate certain liver markers with potential hepatoprotective effects, specifically with long-term and high-dose supplementation.

The methodological quality was low: only 23% of the trials reported adequate allocation concealment and only 46% were considered double blind.
MT versus placebo or no intervention for a median duration of 6 months had no significant effects on all-cause mortality (relative risk (RR) 0.78, 95% confidence interval (CI) 0.53-1.15), complications of liver disease, or liver histology.
Liver-related mortality was significantly reduced by MT in all trials (RR 0.50, 95% CI 0.29-0.88), but not in high-quality trials (RR 0.57, 95% CI 0.28-1.19).

Improvement of liver fibrosis stage (≥ 1) was observed with obeticholic acid 25 mg/day (OR 2.01, 95% CI 1.35-2.98), lanifibranor 1200 mg/day (OR 2.39, 95% CI 1.19-4.82) and silymarin (OR 4.54, 95% CI 1.18-17.43) in traditional meta-analysis.
The results of the comprehensive analysis suggested hypoglycemic drug therapy as an effective intervention for NAFLD, with or without diabetes mellitus.
A prioritized selection of TZDs, vitamin E plus pioglitazone, GLP-1 receptor agonists and FGF-21 analogue may be considered for NASH resolution.
