In the recent years, an increasing number of caffeinecontaining beverages’ consumers have been reported due to the overpopulation and long and inconvenient working hours (Jahrami et al., 2020). Caffeine is an alkaloid that naturally synthesizes in the leaves of tea, seeds of coffee and fruit of cocoa and kola trees, or added to the energy drinks.
