Energy drinks are increasingly consumed due to their perceived ability to enhance physical and mental performance. However, concerns remain regarding their stimulant composition and acidic nature. This study quantitatively determined the concentrations of caffeine, taurine, and titratable acidity in six commercially available energy drink brands sold in Abuja Nigeria namely Predator, Fearless, Climax, Monster, Red Bull, and Power Horse. Caffeine and taurine were determined using High-Performance Liquid Chromatography coupled with Ultraviolet detection (HPLC-UV), while titratable acidity was determined using standard acid–base titration methods. The results showed that caffeine concentrations ranged from 129.14 ± 0.74 to 2186.66 ± 5.95 mg/L, with Climax recording the lowest level, while Power horse had the highest. Taurine concentrations varied between 59.16 ± 0.94 and 378.75 ± 0.83 mg/L, with Fearless exhibiting the highest taurine content and Climax showing the lowest concentration. Titratable acidity values ranged from 5.24 ± 0.20 to 9.77 ± 0.56 g/100 mL, indicating varying degrees of acidity among the samples, with Power Horse and Monster showing relatively higher acidity levels. The low standard deviation values recorded demonstrate the precision and reliability of the analytical methods employed and the observed variations in caffeine, taurine, and acidity among the energy drinks highlight the need for continuous quality assessment and regulatory monitoring to ensure consumer safety. This study provides baseline scientific data on the chemical characteristics of energy drinks and supports the need for stricter regulatory oversight, improved labeling, and increased public awareness regarding energy drink consumption.
