Description

Nadeem Akhtar and fellow members of a United States Pharmacopeia expert committee report a 2026 safety review of turmeric and curcuminoid supplements after scattered reports of liver injury. The committee routinely watches the literature for ingredients in USP monographs and launched a full evaluation to decide whether turmeric products need a caution on their labels.

Animal studies showed liver harm only at high doses of powder or extract, and the many human trials of these supplements reported no organ toxicity or serious events. Published injury cases usually appeared after one to four months of use, often alongside other medicines, and they generally cleared once the supplement stopped. Rare liver failure has occurred, though. The committee recommends a cautionary label advising people with liver history to consult a practitioner and to stop and seek care if symptoms such as jaundice appear.
