ABSTRACT
Over the past three decades, a multitude of dietary supplements has flooded the market, many of which are marketed specifically to athletes. Such supplements often claim to boost athletic performance or to enhance the recovery process. Contamination can occur via the intentional addition of an adulterant, a relatively uncommon practice that can occur primarily with non-reputable sports supplement companies. Alternatively, substance impurity can occur when adulterants are added via cross-contamination. In this scenario, a potentially well-intentioned company can unwittingly contaminate an otherwise good product during production. Though third-party approved dietary supplements are generally considered safe for consumption by healthy adults, some supplements may not be appropriate for certain individuals or populations. Many of the dietary supplements found on the market today are purported to improve various parameters of health. Caffeine, a naturally occurring psychoactive compound, is one of the most popular ergogenic aids and has been studied extensively with regard to physical performance.
