Supplements of the greatest interest for liver health include antioxidants like vitamin E and glutathione, polyphenols like resveratrol and curcumin, omega-3 fatty acids, and milk thistle.[1][2] There are also a number of dietary supplements that have been associated with liver damage, such as pyrrolizidine alkaloid-containing herbs, kratom, large doses of green tea extract, kava kava, black cohosh, and Garcinia cambogia.[3] The dosages at which these supplements reach hepatotoxic levels are unknown, and therefore, avoiding formulations that contain one or more of these ingredients can help to support liver health.
