Turmeric, often touted as a natural panacea, may pose significant risks to liver health, particularly for those with genetic predispositions or when taken in large doses. According to experts, millions of Americans unknowingly put themselves at risk by taking unregulated herbal supplements like turmeric.
The story of Fernanda Thompson, who stopped taking turmeric after experiencing low white blood cells and an enlarged liver, highlights the potential dangers of these substances. A 2024 study estimated that 15.6 million Americans take compounds known to be toxic to the liver daily, with many being unaware of the risks.
Leading experts warn that herbal supplements can cause severe liver damage, including jaundice, abdominal pain, and even life-threatening outcomes like liver transplant or death. Dr. Robert Fontana’s research has found that 20% of cases of liver injury attributed to herbal and dietary supplements are linked to turmeric, ashwagandha, and green tea extract.
While some people may experience mild side effects, others may be at risk for more severe reactions due to genetic susceptibility factors. Dr. Alisa Likhitsup’s research suggests that 43% of cases of liver injury attributed to herbal supplements may be as high as the actual number.
To mitigate these risks, experts emphasize the importance of consulting a doctor before taking any supplement. “The mentality of relying on supplements to achieve a better and longer life is unscientific,” says registered dietitian Dr. Qianzhi Jiang. “Proper nutrition through diet is still the best way to maintain overall health.”
Fernanda Thompson’s experience serves as a reminder that even natural substances like turmeric can pose hidden dangers, and it’s crucial for consumers to prioritize caution when choosing supplements.
