Identification of Genetic Risk Factors Associated With Herbal and Dietary Supplement-Induced Acute Liver Failure Using Whole Exome Sequencing Analysis.

Our assessment

This study investigated whether certain people have a genetic vulnerability to acute liver failure caused by herbal and dietary supplements. Researchers analyzed the complete genetic code (whole exome sequencing) of 23 individuals who developed HDS-induced acute liver failure. They compared these findings to genetic data from large population databases NIH ODS ↗. This is a very small study with only 23 cases, which means the results are preliminary and require much larger follow-up studies before any firm conclusions can be drawn.

How it works

The researchers looked for specific genetic variations that might make some people more susceptible to liver damage from supplements. Think of it like a genetic lock and key — certain genetic differences may make your liver cells more vulnerable to damage from supplement ingredients that are otherwise safe for most people. The study identified specific single-nucleotide polymorphisms (small genetic changes) that were more common in the liver failure patients compared to the general population NIH ODS ↗. What this means for you is that your genetic makeup may influence how your body handles certain supplements, though we don't yet know which specific genes are responsible.

Safety profile

Data not available. This study did not provide adverse event report counts from FDA data. The research focused on genetic analysis rather than cataloging side effects from supplements.

Our recommendation

Because this is a small study with only 23 participants, no change in current supplement practices is warranted based on these findings alone. However, the research reinforces that herbal and dietary supplements can cause serious liver injury in susceptible individuals. If you experience symptoms like yellowing of the skin or eyes, dark urine, or unexplained fatigue while taking any supplement, stop use immediately and consult a healthcare provider NIH ODS ↗. Always discuss supplement use with your doctor, especially if you have pre-existing liver conditions.
