The worldwide increasing prevalence of obesity has led to a corresponding increase in consumption of weight-loss dietary supplements. The limited de novo regulatory oversight and under-reported toxicity profile of these products reflect as a constellation of newer adverse events. We chronicle here the case of an otherwise healthy woman who developed ventricular fibrillation-related cardiac arrest secondary to the use of Hydroxycut and Metaboost preparations. Published medical literature has a handful of case reports associating these products with potentially life-threatening cardiac arrhythmias. The proposed hypothesis implicates ingredients of these diet aids to have proarrhythmogenic effects. Physicians should remain vigilant for possible cardiotoxicity associated with the use of dietary supplements. Individuals who are at risk of developing cardiac arrhythmias should avoid herbal weight-loss formulas, given the serious clinical implications. Additionally, this paper highlights the need for a proper framework to delineate the magnitude and scope of this association.
