Smart Caffeine is a highly effective combination of L-theanine and Caffeine. L-theanine is a natural amino acid found in green tea that removes the undesirable side effects of caffeine, creating long-lasting energy and attention without jitters, anxiety, or a crash.
The benefits include:
Increased focus and alertness
Improved cognitive function
Enhanced short-term memory retention
More ability to ignore distractions
No overstimulation
Smart Caffeine creates a relaxed yet alert state that is ideal for focusing and thinking clearly.
Smart Caffeine is a natural nootropic stack made from coffee and green tea to support a relaxed but alert state that is ideal for productive, focused activity - mental or physical.
The energy and motivation from the Caffeine is harnessed and smoothed over with L-theanine. The result is a focused energy state with improved cognitive function [14] that’s perfect for creative or analytical work. Best of all, there’s no jitters, no crash and no anxious feelings. [15]
Thousands of people use Smart Caffeine every day as a study aid, pre-workout, energy drink replacement or whenever they need a lift.
There have been many recent clinical trials conducted by various organizations proving that the combination of L-Theanine and Caffeine in our same 2:1 ratio increases the ability to focus without the over stimulating effects of Caffeine alone:
A recent study from The Netherlands confirmed that "The combination of L-Theanine and Caffeine improves the cognitive performance and increases subject alertness." and that the combination "helps to focus attention during a demanding cognitive task." [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 positively affect human cognition and caused measurable increases in alpha brain waves - the brain waves associated with alertness. [2]
A UK-based study published in Nutritional Neuroscience found that the combination of L-Theanine and caffeine improved both speed and accuracy of performance when switching between tasks (multi-tasking) and reduced susceptibility to distractions during a memory task. The researchers summarized: "These results replicate previous evidence which suggests that L-Theanine and caffeine in combination are beneficial for improving performance on cognitively demanding tasks." [3]
A Dutch study gave participants L-Theanine and caffeine in the same 2:1 ratio that Smart Caffeine contains, the asked the participants to complete 2 attention tasks at 10 and 60-minutes after ingestions. The researchers stated that "The results support previous evidence that L-theanine and caffeine in combination can improve attention." [4]
A review of multiple studies published by the School of Psychology in Australia concluded that "L-theanine may interact with caffeine to enhance performance in terms of attention switching and the ability to ignore distraction; this is likely to be reflective of higher-level cognitive activity." [5]
New research from Korea has shown the amino acid L-Theanine (commonly found in tea) inhibits the excitatory effects of caffeine (you'll be less jittery) and "low doses of L-theanine can partially reverse caffeine-induced reductions in Slow Wave Sleep (the transition from wakefulness to sleep); however, effects of L-theanine on caffeine-induced insomnia do not appear to increase dose-dependently."
L-Theanine can reduce jittery effects of caffeine and helps prevent sleeplessness caused by caffeine consumption. [6]
Another study from neuroscience labs here in the US found that L-Theanine in combination with caffeine had positive effects on both tonic (background) and phasic (event-related) cognition.
In this study, participants were dosed placebo, caffeine only and caffeine + L-Theanine. The participants that received the combination of caffeine + L-Theanine demonstrated significantly greater increases in mental performance than both the caffeine-only and the placebo groups. [7]
Take a serving of 1-2 capsules whenever focused energy is desired. Avoid use in the evening. Total daily dosage should not exceed 6 capsules.
SMART CAFFEINE™ can be taken daily, however we advise taking 1-2 days off per week (weekends for example).

Better than you regular caffein!
Works amazing! I get a huge boost of energy without a crash and it lasts for hours!
Smart Caffeine so far has been one of the best energy supplements I've purchased.
I bought this with my first order of Magtech for kicks. i had no idea what a great supplement it turned out to be. See my Magtech review for more details. I use it for targeted situations, like karate belt tests or for night work. ( I am in IT ) . It does not make you jittery, just very focused. My college kids found it and used it to study and take their finals. They aced them! ( granted they are 4.0 students anyway) still they are going to use it for all their tests next semester! I am going to have to hide it or buy more!
