Estimation of Caffeine and Vitamin B-Complex (Vitamin B2, B3, B5 and B6) Constituents of Selected Energy Drinks

Vitamins are important nutrients that are contained in food and carry out distinct and important bodily tasks that are required for sustaining good health. A xanthine alkaloid known as caffeine is widely distributed in natural plant sources such as coffee, cocoa beans, cola nuts, and tea leaves. Additionally, it is a raw material in several drinks. Its usage increases blood pressure, diuresis, blood sugar, generation of stomach acid and pepsin, plasma levels of fatty acids, cortisol, and epinephrine, intraocular pressure, and calcium loss, which causes bone loss. The phrase "energy drinks" refers to beverages that advertise that they will give you an energy boost, which has led to an increase in the popularity of "energy drinks" that include caffeine. The caffeine and vitamin B-complex concentrations of a few different energy drinks were tested and compared in this study project. Samples of ten (10) different energy drink brands were chosen at random from Nkwo Ogbe Market in Ihiala, and their caffeine and vitamin B1, B2, B6, and B12 concentrations were determined using a spectrophotometric technique. The findings revealed that caffeine concentrations varied from 1.11 mg/L to 2.13 mg/L, and that vitamin B1 in energy drinks had the lowest value (0.014 mg/kg). All samples of energy drinks had caffeine levels below the 400 mg/L benchmark set by the National Agency for Food and Drug Administration and Control (NAFDAC). In order to avoid negative consequences, it is important to monitor any decrease in intake of these beverages because other criteria, such as aspartame and sugar, were also often below the established levels.
