Abstract
BACKGROUND

Pre-workout supplements (PWS) are advertised as popular wellness products, despite several “fat burners” being linked to hepatotoxicity. OxyShred thermogenic fat burner (OxyShred) is a PWS that has been rising in popularity and contains several hepatotoxic ingredients, including Garcinia cambogia. We present the first report of acute liver failure attributed to OxyShred use.

CASE SUMMARY

A 31-year-old woman with hypertension and obesity began using OxyShred as a PWS. After nine weeks, she was admitted with fatigue, emesis, and jaundice and found to have acute hepatocellular liver injury, which progressed to liver failure requiring transplantation.

CONCLUSION

Physicians should carefully screen for PWS use, caution against unregulated use, and advocate for increased regulation of herbal supplements.

Core Tip: Pre-workout supplement (PWS) use has grown rapidly with the expanding fitness market, yet many products contain poorly regulated herbal ingredients linked to liver injury. Multi-ingredient supplements cause most herb-related hepatotoxicity, and consumers often assume they are regulated despite minimal oversight. OxyShred thermogenic fat burner (OxyShred), a popular PWS, includes several agents associated with liver damage. A healthy 31-year-old woman developed acute liver failure requiring transplantation after eight weeks of consistent OxyShred use. This case highlights the risks of unregulated supplements, the need for physician inquiry about PWS use, and the importance of stronger federal requirements for safety evidence and ingredient transparency.
