S-adenosyl-L-methionine (SAMe) is a naturally occurring compound involved in methylation reactions, transsulfuration, and aminopropylation in the body. Its role in liver health and detoxification is supported by moderate scientific evidence, particularly in the context of liver diseases such as cholestasis, cirrhosis, and non-alcoholic fatty liver disease (NAFLD). Several clinical trials and meta-analyses suggest that SAMe supplementation can improve biomarkers of liver function, including reductions in serum bilirubin and liver enzymes (ALT, AST, ALP), especially in patients with intrahepatic cholestasis and alcoholic liver disease. The proposed mechanism involves SAMe’s function as a methyl donor in the synthesis of glutathione, a key antioxidant critical for hepatic detoxification pathways.

However, while there is evidence for improvement in biochemical markers, the data on long-term clinical outcomes (such as mortality or progression to liver failure) are limited and somewhat inconsistent. Most guidelines do not recommend SAMe as a first-line therapy, but it may be considered as an adjunct in certain conditions, especially where standard therapies are inadequate or contraindicated.

In summary, the use of SAMe for liver detoxification is scientifically supported to a moderate degree, primarily based on its mechanistic role in hepatic biochemistry and some positive clinical trial results, but more robust, large-scale studies are needed to confirm its efficacy for broader liver detoxification or disease prevention.
