Purposive and convenience sampling were used to select three energy drinks for each brand, a total of 12 energy drinks were used. Two methods, iodometry and spectrophotometry were used to analyze caffeine in the samples. The comparative results of the study showed that, there were significant differences in levels of caffeine in drinks. The study also established that spectrophotometry results were higher while iodemetry results were lower, but all values were close range of the labelled container.
