Why Choose Smart Caffeine with L-Theanine from Natural Stacks?
Smart Caffeine is a nootropic dietary supplement formulated with natural coffee and green tea ingredients designed to support alertness without the negative side effects associated with drinking coffee making it ideal for helping you navigate challenging tasks whether they’re mental or physical.
The 2:1 combination of caffeine and L-Theanine (derived from green tea) results in a state of focus and enhanced attention whilst remaining relaxed and calm. Essentially, it provides all of the advantages of caffeine but removes the coffee jitters, the energy trough and potential anxiety that can come with drinking coffee making it the perfect solution for when you need a boost in your professional life or social circle.
Various studies have been carried out on the benefit of combining caffeine and L-Theanine which have shown that it can increase our ability to focus without the overstimulation associated with caffeine on its own.
A recent Netherlands study found that “The combination of L-Theanine and Caffeine improves cognitive performance and increases subject alertness.” and that the combination “helps to focus attention during a demanding cognitive task.”
In a similar study, The Cognitive Neurophysiology Laboratory in New York conducted testing for 4 days on volunteers from the age of 21 and 40 and concluded that the combination of L-Theanine and Caffeine positively affect human cognition and caused measurable increases in alpha brain waves – important brain waves associated with both alertness and calmness.
L-Theanine has been shown to reduce the negative side effects that caffeine can have on the body such as jitters and caffeine slumps that result in fatigue making it the perfect leveller for Smart Caffeine.
