Caffeine, a methylxanthine alkaloid, is perhaps the most widely consumed stimulant in the world, found in various foods of plant origin such as coffee, cocoa beans, tea leaves, guarana berries, and kola nuts. Other caffeine-containing products include sports and energy drinks and foods, food supplements and over-the-counter headache medications. When ingested, caffeine has numerous physiological and neurological effects, including diuresis, central nervous system stimulation, and insomnia. It acts as an antagonist of adenosine receptors, increases the release of adrenaline and endorphins, and reduces the perception of effort and fatigue during exercise.
Excessive consumption of caffeine from various sources, including caffeinated beverages, can have significant adverse effects such as severe hypertension, cardiac arrhythmias, seizures, and even death. The combination of caffeine with other stimulant substances can also significantly increase its effects.
Because caffeine is found in a variety of coffee, tea, and cocoa products, only beverages to which caffeine has been added, such as food supplements and energy drinks, must be labeled with the amount of caffeine the beverages contain. Caffeine-containing food supplements marketed as energy boosters or weight loss aids are widely available in numerous retail stores.
Valid quantitative analysis is required to ensure the quality and credibility of the labeled content. We offer quantification of caffeine in a variety of food supplements, beverages and foods using the validated HPLC-UV method.
After sample delivery you will receive your analysis results in 3 to 5 business days.
