Medical researchers have linked turmeric supplements to rare cases of drug-induced liver injury, identifying 15 specific instances among patients. One individual in the studied group died after experiencing symptoms including fatigue, nausea, and jaundice.

Why it matters

The findings highlight potential health risks associated with increasingly popular herbal supplements. Researchers suggest that certain additives like piperine may increase liver exposure to these products.

A study of 10 turmeric-linked cases identified that 7 patients carried the HLA-B*35:01 gene, while 3 of the products consumed contained piperine. Symptoms typically manifested within 84 days of starting supplement use.

The players

American College of Gastroenterology

This professional organization representing specialists in digestive diseases presented the 15 case studies on liver injury.

US Drug-Induced Liver Injury Network

This research network tracks cases of liver damage suspected to be caused by medications or dietary supplements.

The details

Researchers found that patients aged 49 to 64 experienced liver injury after taking turmeric, with clinical studies indicating a potential link to specific genetic markers. Of the 345 supplement-related liver injury cases documented in the US Drug-Induced Liver Injury Network, 10 were specifically attributed to turmeric.

Timeline

  1. The first turmeric-linked liver injury cases occurred in 2011.

  2. The majority of identified liver injury cases began in 2017.

  3. Turmeric became the fourth-highest-selling herbal supplement in 2020.

  4. A clinical research study on liver injury was published in October 2022.

  5. New research was presented at a gastroenterology meeting on September 18, 2026.

Health Landscape

This research follows the established monitoring protocols of the US Drug-Induced Liver Injury Network's surveillance of dietary supplements. It marks a significant update to the scientific understanding of how specific herbal additives contribute to liver injury.

Individuals taking turmeric supplements should monitor for symptoms such as jaundice, fatigue, or nausea. Those with specific genetic markers may face an increased risk, making it essential to discuss supplement use with a healthcare provider.

The takeaway

While turmeric is a common herbal supplement, its potential to cause rare liver damage necessitates caution for consumers. Understanding the specific additives and individual genetic risks can help individuals make more informed decisions about their dietary routines.
