Research demonstrates that a combination of 165mg of caffeine and 100mg of L-theanine can enhance alertness and cognitive performance by up to 20%, while reducing the likelihood of jitters and energy crashes. L-theanine promotes relaxation and mental clarity, effectively balancing the stimulant effects of caffeine. This evidence-based formulation provides a natural means to support sustained focus and mental acuity throughout the day.
