Abstract
A 26-year-old male was presented to a military treatment facility in Afghanistan shortly after taking a weight-lifting supplement called Jack3d with a severe headache and was subsequently found to have suffered a Dejerine-Roussy variant right thalamic hemorrhagic stroke. Jack3d active ingredients include geranamine, schizandrol A, caffeine, beta-alanine, creatine monohydrate, and L-arginine alpha-ketoglutarate. A literature search revealed case reports suggesting some of the constituent ingredients may predispose to stroke and hemorrhage and also revealed a substantial paucity of data existed regarding schizandrol A, a herb used in traditional eastern medicine. The product has no readily apparent disclaimer or warning regarding the risks or lack of data regarding the components. Jack3d is sold as a nutritional supplement and is therefore not subject to same FDA regulation and scrutiny that a pharmaceutical receives. The potential adverse effect was reported to the FDA via MedWatch in accordance with the recently passed Dietary Supplement and Nonprescription Drug Consumer Protection Act.
