Being tired or drained is simply not fun, especially if you want your brain working at its highest performance level.

That's why caffeine is consumed by millions worldwide.  It's an efficient natural stimulant that is well tolerated by many people, and Caffeine can definitely give you a nice edge on your energy levels. Numerous studies have shown that Caffeine supplements increase energy and concentration. [1]  

But it's not the type of energy and concentration you want for productivity.

On its own, Caffeine is not a great cognitive enhancer. Users often experience a jittery or anxious mental state followed by a crash, especially in people that have built up a tolerance. Drinking a sugary coffee or energy drink doesn't provide the type of energy and concentration you need to get things done. That's why we include L-theanine (L-tay ah neen) in SMART CAFFEINE™.  It's a naturally occurring amino acid with benefits that include mental relaxation, reduced stress, improved working memory, enhanced learning, and perhaps most importantly, increased alpha brain wave activity. [2]

Independently, Caffeine and L-Theanine have somewhat polar effects on the mind and body. However when the two are combined the effects do not simply negate one another. Instead they work together very synergistically, allowing the user to fully benefit from the positive aspects of both compounds without the negative side effects. The energy and motivation from the Caffeine is harnessed and smoothed over with L-theanine. 

This Natural Stack provides a clear and focused energy feeling, rather than the short-lived stimulant rush of Caffeine by itself.

Many scientific studies have shown that SMART CAFFEINE's ingredients, Caffeine and L-theanine, have the following benefits when taken together; increased focus and alertness [3], improved cognitive function [4], enhanced short-term memory retention [5], more ability to ignore distractions [6], no overstimulation [7].

Quick Facts:

  • L-theanine and Caffeine is the #1 recommended beginner's Nootropic stack at the excellent r/Nootropics community on reddit.com.
  • L-theanine (y-glutamylethylamide) is found almost exclusively in the tea plant. Some teas have more than others. The average green tea drinker consumes about 20 mg of L-theanine a day. That's why people may feel relaxed, calm, and focused after drinking several cups of tea. However you would have to drink many cups of tea to reach most desired nootropic effects of L-theanine.

There have been many recent clinical trials conducted by various organizations proving that the combination of L-Theanine and Caffeine increases the ability to focus without the over stimulating effects of Caffeine alone:

A recent study on young adults discovered that "The combination of L-Theanine and Caffeine improves the cognitive performance and increases subjected alertness." [1]

The Cognitive Neurophysiology Laboratory in New York conducted testing for 4 days on volunteers from the age of 21 and 40 and found that "L-Theanine and Caffeine in combination affect human cognition as evidenced by oscillatory alpha-band activity and attention task performance." [2]

A study on the cognition and mood of healthy volunteers found that "The L-Theanine and Caffeine combination improved both speed and accuracy of performance of the attention-switching task, and reduced susceptibility to distracting information in the memory task. These results replicate previous evidence with suggests that L-Theanine and caffeine in combination are beneficial for improving performance on cognitively demanding tasks." [3]

In a detailed study, the researchers concluded that "The results support previous evidence that L-theanine and caffeine in combination can improve attention." [4]

A literature review from the School of Psychology in Australia stated that "L-theanine may interact with caffeine to enhance performance in terms of attention switching and ability to ignore distraction." [5]
