Rating (out of 5): 2

Chlorogenic acid is a polyphenolic compound found in coffee, certain fruits, and vegetables. There is some emerging scientific evidence supporting its use for hepatic (liver) health, though this evidence is largely preclinical. Animal studies have indicated that chlorogenic acid may have hepatoprotective effects, such as reducing oxidative stress, lowering inflammation, and improving lipid metabolism in the liver. For example, rodent models of chemically induced liver injury have shown that chlorogenic acid administration can attenuate liver damage and markers of inflammation. Some mechanisms proposed include antioxidant activity, modulation of glucose and lipid metabolism, and anti-inflammatory effects.

However, human clinical data are limited. While some small studies suggest possible benefits in metabolic syndrome or non-alcoholic fatty liver disease (NAFLD), these findings are preliminary and not definitive. The majority of evidence is indirect, focusing on improved metabolic parameters rather than direct measures of liver function or disease outcomes. Chlorogenic acid is not widely recognized in traditional medicine specifically for liver support, so its use in this context is primarily based on modern research rather than longstanding practice.

In summary, while there is some scientific rationale and preclinical evidence for chlorogenic acid supporting the hepatic system, high-quality human studies are lacking. The current evidence base is modest, hence a rating of 2 out of 5.
