The Energy Blend

Elixir contains 140mg of caffeine and 360mg of L-theanine. This combination provides a smoother, longer-lasting energy boost compared to caffeine alone. While caffeine typically lasts 4-6 hours with a noticeable peak and potential crash, L-theanine extends alertness and focus to 5-7 hours. It also reduces the intensity of the peak and the severity of the crash, delivering a more balanced and sustained energy experience.

Studies show that combining caffeine with L-theanine not only enhances focus and alertness but also improves cognitive performance and task efficiency. This synergistic effect helps maintain mental clarity and productivity without the jittery side effects often associated with caffeine alone.

 

Basically, people feel more focus, longer energy, and less jittery/anxious. 

Energy Blend - Caffeine + L-Theanine

Increases focus, Energy And Reduces anxiety & Jitters

Owen et al. (2008)

Found that the combination ofcaffeine and 100 mg L-theanine improved both speed and accuracy in attention-switching tasks and reduced susceptibility to distracting information, compared to caffeine alone, which only improved subjective alertness and accuracy on attention-switching tasks.

 

Kahathuduwa et al. (2017)

Demonstrated that the combination of caffeine and L-theanine significantly improved recognition visual reaction time (RVRT) and elicited larger N2-P300 ERP amplitudes compared to caffeine alone, indicating enhanced attention.

 

Haskell et al. (2008)

Reported that the combination of caffeine and L-theanine improved rapid visual information processing (RVIP) accuracy, mental fatigue ratings, and reaction times in various cognitive tasks, suggesting a synergistic effect on cognitive performance and mood.

 

Giesbrecht et al. (2010)

Found that a combination of L-theanine and caffeine significantly improved accuracy during task switching and self-reported alertness, compared to caffeine alone.
