01/ CAFFEINE AND L-THEANINE FOR CLEAN ENERGY AND NO CRASH

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.

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.”

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.

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.”

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.”

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.”

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.

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.

    Awesome Products
    I use the Natural Caffeine supplement. I usually take one pill in the morning before work and it gives me a steady jolt of energy, without the gitters that coffee gives. Great product overall.

    it works
    if you need to feel focused for a specific project I highly recommend this product, I used it in combination with CILTEP (2 capsules fasting) and it worked much better than just taking the CILTEP by itself.

    Amazing!
    I have focused energy and it lasts at least 5-6 hours. Taking 2 at one time is perfect for a work day.

    “fantastic supplement!
    Smart caffeine provides long lasting energy without the normal caffeine crash or jitters. Much easier to take a pill in the morning and another in the afternoon than drink coffee all day!”
