Dietary and Herbal Supplements Linked to Liver Damage
1. Turmeric
Turmeric is a popular dietary supplement for managing arthritis, digestive problems, and liver disease. However, some evidence suggests that turmeric supplements may damage the liver. Supplements with black pepper may cause additional harm since this enhances turmeric absorption.
A 2023 study showed an increase in turmeric-induced liver injuries in the U.S. The researchers examined data from the U.S. Drug-Induced Liver Injury Network between 2004 and 2022. Only ten cases of turmeric-related liver injuries were reported, but six of these occurred since 2017.
2. Green Tea
Green tea supplements have been marketed as weight loss and cancer-fighting agents. Consuming too much of a specific compound in green tea – epigallocatechin gallate (EGCG) – may harm the liver.
"Regular tea drinking, about 3 to 5 cups per day, does not pose the same risk, as dietary intake provides much lower levels of EGCG," said Caroline Susie, a Dallas-based registered dietitian and spokesperson for the Academy of Nutrition and Dietetics.
3. Ashwagandha
Some people take ashwagandha for stress relief or to support overall health. There have been reports of ashwagandha-related liver injuries in the U.S.
"The precise toxic threshold is unknown, but reported cases involve high-dose extracts rather than traditional root powders," Susie said.
While high-dose extracts may cause harm, low dietary intake of ashwagandha is generally safe. It is essential to speak with a trusted healthcare provider before taking ashwagandha, especially if you have a history of liver disease. Taking ashwagandha with other supplements might cause interactions and increase the risk of liver damage.
Conclusion
The study highlights the importance of being aware of the potential risks associated with certain dietary and herbal supplements. It is crucial to consult with a healthcare provider before taking any supplement, especially if you have a history of liver disease. Additionally, be cautious when taking multiple supplements together, as this may increase the risk of liver damage.
