If you’re like most Americans, you probably down a daily multivitamin or take turmeric pills from time to time. About 58% of U.S. adults 20 and older, including 64% of women and 51% of men, reported consuming a dietary supplement in the past 30 days, according to the 2017–18 National Health and Nutrition Examination Survey. A 2024 poll from the Council for Responsible Nutrition (CRN), a dietary supplement trade association, suggests usage is even higher, with 75% of U.S. adults 18 and older taking dietary supplements.
Nearly all users in the CRN survey (91%) said supplements are essential to maintaining their health—which is why it’s so troubling that supplement-spurred liver damage is skyrocketing. A 2022 study published in the journal Liver Transplantation found that drug-induced acute liver failure tied to herbal and dietary supplements had increased eightfold from 1995 through 2020. What’s more, herbal and dietary supplements account for roughly 20% of liver toxicity cases nationwide, according to 2017 research published in the journal Hepatology.
