Berberine + Milk Thistle Combination for Liver Health

Research suggests that both berberine and milk thistle (silymarin) have been studied individually in the context of metabolic dysfunction-associated steatotic liver disease, formerly known as nonalcoholic fatty liver disease, with a 2025 systematic scoping review identifying them among the bioactive substances with a meaningful body of published evidence for liver-related outcomes. The review, which synthesized findings from 131 primary studies and 49 systematic reviews published between 2000 and 2023, found that silymarin and curcumin were the most extensively studied compounds, while berberine also appeared among the examined interventions, with outcomes measured including liver health markers, blood lipids, blood sugar, and body composition. However, direct evidence for a berberine and milk thistle combination specifically is not established by this review, which evaluated these substances largely as separate interventions rather than as a paired regimen. The authors noted considerable variability in study methods and findings across the literature, concluding that more rigorous and consistent research is needed before firm conclusions about clinical effectiveness can be drawn for any of the substances examined.
