Sharp Rise in Turmeric-Linked Liver Accidents
In keeping with a brand new examine printed in The American Journal of Drugs, researchers from the Drug-Induced Liver Harm Community (DILIN) recognized ten confirmed circumstances of turmeric-associated liver harm between 2011 and 2022. Whereas the quantity could seem small, the severity and patterns of the accidents make these findings important.
Listed here are the important thing statistics:
- 8 out of 10 sufferers have been girls
- 9 out of 10 have been White
- The median age was 56 years, starting from 35 to 71 years
- 9 of the ten confirmed a hepatocellular sample of liver damage, just like that seen in hepatitis
- 5 sufferers have been hospitalized, and 1 affected person died from acute liver failure.
- 7 of seven dietary supplements examined contained turmeric, and 3 additionally contained piperine
- 7 sufferers carried the HLA-B*35:01 gene, and 2 have been homozygous, giving an allele frequency of 0.450, in comparison with simply 5.6–6.9% within the common inhabitants
These numbers spotlight a possible genetic and chemical vulnerability that had largely gone unnoticed.

Why Turmeric Would possibly Not Be as Innocent as It Appears
The Position of Piperine: Too A lot of a Good Factor?
Turmeric’s energetic compound, curcumin, is poorly absorbed by the human physique by itself. To spice up its effectiveness, many complement producers add piperine, derived from black pepper. This compound can enhance absorption by as much as 2,000%, however can also amplify poisonous results on the liver.
Of the dietary supplements analyzed on this examine, three contained piperine—elevating the likelihood that this frequent enhancer could play a job in liver sensitization or harm.
Genetic Threat: The HLA-B*35:01 Connection
The examine additionally revealed a outstanding genetic sample. The HLA-B*35:01 allele, beforehand related to inexperienced tea extract-induced liver harm, was present in 7 out of 10 turmeric-injury sufferers. Two sufferers have been homozygous, which means they inherited the gene from each dad and mom.
To place that into perspective, solely about 6% of the final inhabitants carry this allele—in comparison with 45% on this examine cohort. This putting distinction strongly factors towards a genetic predisposition that would make turmeric dietary supplements harmful for some people.

What the Accidents Seemed Like
Sufferers sometimes developed signs similar to jaundice, belly ache, fatigue, and nausea inside weeks to some months of beginning turmeric dietary supplements. Lab work revealed elevated liver enzymes, and liver biopsies in 4 sufferers confirmed proof of acute hepatitis or blended cholestatic-hepatitic damage, typically with eosinophil infiltration—a marker of allergic or immune-mediated harm.
One affected person sadly died of acute liver failure, whereas 5 others required hospitalization. The rest improved after stopping turmeric dietary supplements, however not with out present process a battery of exams and, in some circumstances, receiving immunosuppressive remedy.
Why This Issues Now
Turmeric is extra standard than ever. From wellness influencers to well being meals cabinets, it is seen as a cure-all for every part from joint ache to digestive points. However in contrast to prescription medicines, natural dietary supplements aren’t tightly regulated. This implies their composition, focus, and purity can differ extensively, even between batches of the identical model.
The present findings function a wake-up name for customers and well being professionals. All examined dietary supplements within the examine contained turmeric, however none warned of attainable liver dangers. And people with piperine—generally marketed as a profit—would possibly really pose a hidden hazard.
Don’t Ignore the Dangers of “Pure” Treatments
Turmeric, whereas helpful for a lot of, is not risk-free. This examine highlights that liver damage—although uncommon—can happen, particularly in genetically inclined people or these utilizing high-dose, enhanced-absorption formulations.
When you’re utilizing turmeric dietary supplements and develop signs like yellowing of the pores and skin or eyes, darkish urine, unexplained fatigue, or belly ache, don’t dismiss them. Discontinue use and search quick medical consideration.
Much more importantly, discuss to your physician earlier than beginning any complement. Ask whether or not you is perhaps in danger—and whether or not you really want it in any respect.
