There are many benefits of 1-2-Go that come from the individual ingredients and the synergy between them. While the main ingredients, l-theanine, theobromine, and caffeine, provide individual benefits, there are other advantages of using these ingredients together. Caffeine is a well known stimulant that many people consume daily; taking pure caffeine (caffeine andryhrous) may give you energy, however it is often coupled with negative side effects such as jitters, and over stimulation. L-theanine is an amino acid that is derived from green tea the provides cognitive benefits and stress relief. The combination of caffeine and l-theanine has been studied and is shown to improve alertness and reduce susceptibility to distraction. Like caffeine, theobromine is an alkaloid commonly found in chocolate and tea and both are considered as one of the primary reasons that chocolate and tea have cognitive enhancement benefits.
The dosage is dependent upon the individual, but most individuals should take the dose recommended on the bottle; this product contains about the same amount of caffeine as would be found in a cup of coffee. Individuals that do not consume caffeine regularly should avoid taking 1-2-Go in the evening so they do not impair their sleep. It is recommended that an individual take 1-2-Go at least 30 minutes before they need to focus.
The toxicity studies on caffeine demonstrate that it is relatively safe for human consumption; this is of course not without it limits because there are instances of caffeine overdose. A lethal dose of caffeine is said to be around 10 grams which is over 100 x times as much caffeine in a 1-2-Go capsule. L-theanine is Generally Recognized As Safe (GRAS) by the United States Food & Drug Administration. Finally, the amount of theobromine in a 1-2-Go capsule is less than one would find in an ounce of dark chocolate; it should be noted that theobromine is one of the primary reasons that dogs should not have chocolate (as they cannot metabolize the theobromine like a human).
