This study investigates the caffeine content in fourteen different local carbonated and energy drink brands, utilizing UV spectrophotometry for rapid and accurate caffeine quantification. The results reveal a significant variation in caffeine concentrations across the samples, with the energy drink XL(I) exhibiting the highest concentration at 520 µg/ml, while the Tender coconut drink contained the lowest at 52.37 µg/ml. Additionally, the findings indicate that imported soft drinks generally contain higher caffeine levels than their domestic counterparts. These measurements are compared to the Recommended Daily Intake (RDI) for caffeine, providing insights into the potential consumption patterns of caffeine in soft drink products.
